35+ Scary Movies Based on True Stories

Horror movies are already scary enough, but these scary movies based on true stories up the creepiness volume very, very high.

Horror movies are already scary enough, but watching a scary movie based on a true story turns the creepiness volume up very, very loudly.

For the purposes of this article, it’s necessary to explain the difference between a movie based on a true story and one inspired by a true story. If it’s based on a true story, you can expect it to faithfully follow the details of what happened. But as you might notice, several of the movies below were inspired by real life elements. There are also creators who intentionally obscure which parts of their films are fictional.

Horror director Tobe Hooper started the “based on a true story” trope by marketing his movie The Texas Chainsaw Massacre (1974) as based on a real crime when the plot didn’t resemble any real crime at all and merely took some inspiration from the murderer and necrophile Ed Gein. More than a successful marketing ploy, Hooper said he was inspired to market his film based on a lie because he felt lied to by the U.S. government about then recent events like Watergate and the Vietnam war. In real life American families were sitting down to watch the evening news and seeing violent video footage of war for the first time in history and were becoming aware they weren’t getting the full story about what they were seeing. In The Texas Chainsaw Massacre not only is the villain wearing a man mask (conveying the idea that the real horror isn’t paranormal or coming from outer space, it is literally “man-made”) but we have no idea what information we can trust, just like in life outside of the movie.

These horror films are all the more horrifying because in some way they are based on reality, not just imagination. Here are all the best scary movies based on true stories, and the story behind the story.

The Exorcist (1973)

Linda Blair’s character in The Exorcist was inspired by a real-life story of a boy who died in the midst of multiple exorcisms.

One of the most successful horror movies of all time, and one that could reasonably be cited as one of the reasons for the “Satanic Panic” of the 1980s, was inspired by the real-life tale of a boy from Maryland who was named “Roland Doe” to protect his real identity.

Extremely odd things started happening as Roland reached adolescence in the late 1940s: scratching sounds in the basement, beds suddenly shaking, the sudden smell of excrement filling the room, etc. A student who shared a class with Roland recalls one incident:

“The desk was shaking and vibrating extremely fast and I remember the teacher yelling at him to stop and I remember he kind of yelled back ‘I’m not doing it!”

Just as in The Exorcist, things escalated from there. Roland’s parents gave up hope that his condition was medical and instead turned to the Catholic Church for an exorcism. He went through dozens of exorcisms.

Years later, notes where found in the St. Louis institution where the exorcisms were performed, graphically detailing the events as they happened. Author William Peter Blatty became privy to the notes. He changed the main character from a boy to a girl, wrote a novel called The Exorcist, and the rest is history.

The Exorcist was a huge commercial success, becoming one of the most popular movies of all time with people waiting in long lines just to see the film based on word of mouth. After seeing the movie some viewers became dizzy, vomited, developed insomnia, and even had miscarriages. A new term, cinematic neurosis, was coined to describe the phenomena. The film also created a “Satanic Panic” that is responsible for the death of at least one mentally ill girl whose parents were convinced she was demonically possessed.

The Town That Dreaded Sundown (1976)

The “Phantom Killer” or “Phantom Slayer” was a masked killer and a real person near Bowie County, Texas.

In the spring of 1946 a masked killer stalked, murdered, and terrorized people in the twin cities of Texarkana, Texas and Texarkana, Arkansas. Within a 10-week time span, the killer assaulted eight people, murdering five of them. Like the Zodiac killer, most of the murders took place near lover’s lanes.

The media referred to these killings as the “The Texarkana Moonlight Murders,” and Charles B. Pierce’s The Town That Dreaded Sundown retells the story on the silver screen. The two people who survived attacks by the Phantom could only describe him as about 6 feet tall and wearing a pillowcase with eye holes cut out. The name of the movie refers to the hysteria the area went into with so many murders in such a short amount of time. Police investigated over 400 suspects, but the identity of the Phantom Killer remains unknown.

The Town that Dreaded Sundown is heavily fictionalized. For instance, the infamous “trombone” scene was scripted for morbid entertainment value, there is no evidence that the Phantom killed anyone this way. The closest link to reality is that one of the victims was playing a saxophone in a band the night she was killed. The movie also has a series of strange moments of comic relief.

A remake of the film was made in 2014, and the 1976 version is screened in Texarkana every year on Halloween.

The Texas Chainsaw Massacre (1974)

Sally Hardesty being terrorized in this 70s serial-killer film.

It’s impossible to call this classic film “real.” It’s a work of fiction more or less through and through. That said, some inspiration for the character of Leatherface comes from a real-life murderer/body snatcher, Ed Gein, also known as the Butcher of Plainfield or the Plainfield Ghoul.

The film’s main killer, “Leatherface,” was fictional, but in real life, Ed Gein made masks and other wares out of human bodies. Director Tobe Hooper also says his film was inspired by Texas killers Elmer Wayne Henley and Dean Corll, who lured and slaughtered boys near Houston in the early 1970s. Hooper’s writing partner, Kim Henkel, said he saw a news interview with Elmer Wayne that laid the foundation for Texas Chainsaw‘s cannibal family: “He had this conventional morality at that point. He wanted it known that, now that he was caught, he would do the right thing. So this kind of moral schizophrenia is something I tried to build into the characters.”

Eaten Alive (1976)

Roberta Collins in Eaten Alive (1976).
Eaten Alive has gone by many other titles, including Death Trap, Horror Hotel, and Starlight Slaughter.

Eaten Alive (1976) is a campy exploitation film directed by Tobe Hooper. The movie is about the owner of a run-down hotel in Texas who murders and/or feeds people to his pet crocodile. The owner, Judd (Neville Brand), and the basic premise of Eaten Alive were inspired by a man named Joe Ball whose real crimes grew to urban legend status in parts of Texas.

According to Texas Monthly, After prohibition ended, Joe Ball opened a tavern in the small town of Elemdorf, Texas (near San Antonio). Ball’s tavern was known locally because of its rowdy clientele, and also because of the live alligators Ball kept in a pool out back. A main attraction at the tavern was feeding time for the alligators, and Ball would sometimes throw in live cats and dogs to please his audience.

Multiple disappearances of women in Ball’s life (who either worked for him or were romantically involved with him) led police to begin investigating Ball… at which point he committed suicide. Ball is known to have killed two women. No evidence was ever found that Ball fed anyone to his alligators, but the rumors spread and grew over the years regardless. Though many of the women who supposedly disappeared from Ball’s life were eventually found to be alive, some were never located. As casual as Ball seemed to be about killing, it’s entirely possible there is a lot of truth the rumors.

The Amityville Horror (1979)

A true horror story that happened in New York state according to the Lutz family.

The truest horror story that happened in the home at 112 Ocean Avenue in Amityville, NY is that on November 13, 1974 Ronald DeFeo, Jr. shot and killed his parents, brothers, and sisters, annihilating his entire family while they slept. DeFeo confessed to the murders but pled insanity during his trial. An insanity plea involves not whether the defendant experiences mental health issues, but whether they were, at the time of the crime, unaware that the crime was wrong. As part of DeFeo’s confession involved telling police how he discarded evidence, he was clearly aware that what he had done was wrong. He was convicted of six counts of second degree murder and died in prison in March 2021.

One year after the DeFeo murders, George and Kathy Lutz bought the house and moved in with their three children. The Lutz family fled the Amityville home in the middle of the night 28 days later after experiencing an increasingly malevolent haunting. The family claims they saw glowing red eyes, experienced sudden levitation, and saw objects fly around the room. George Lutz says he kept waking up at 3:15AM—the time the DeFeo murders happened. The Lutz family story was immortalized in the best-selling Jay Anson book The Amityville Horror and subsequently made into the 1979 film starring James Brolin and Margot Kidder. There are now over 30 films based on the Amityville haunting and the story is likely responsible for one of the highest grossing horror franchises of all time, The Conjuring, which follows paranormal investigators Ed and Lorraine Warren.

Many people have come forward to debunk the Amityville haunting including the priest the Lutz family say blessed the home and the subsequent owners who could not verify the damage described in the book. In 1979, the lawyer who represented Ronald DeFeo Jr. in his murder trial, William Weber, told People “I know this book is a hoax. We created this horror story over many bottles of wine.”

After decades of silence, Daniel Lutz—who was in his teens when the family lived there—came forth with a documentary called My Amityville Horror (2013) and insisted it had all happened: “I was possessed by a spirit I couldn’t get rid of on my own. I just wanted somebody to believe me. It has been in my dreams my whole life.”

The Entity (1982)

This movie tells the tale of assault and parapsychology.

The Entity (1982) is inspired by the 1974 case of Doris Bither, a mother of four who alleged that the ghosts of three men were sexually assaulting her. Bither was studied by doctoral students in parapsychology at University of California, Los Angeles, and the case became known as “the Entity haunting.” It’s probably not a coincidence that this event took place at the height of The Exorcist‘s popularity.

The movie takes many liberties and is a generally well-received horror/thriller movie from the 80s. On closer inspection, despite the sexual violence, it is also a rather feminist tale with an incredibly powerful female lead played by Barbara Hershey.

Poltergeist (1982)

Carol Anne (Heather O’Rourke) sees a ghost and a creepy doll sits by her in Poltergeist.

Steven Spielberg created the story used for Poltergeist (1982), and Tobe Hooper directed the collaboration. Spielberg says he conceived of the idea as a sequel to his film, Close Encounters of the Third Kind (1977). This time, rather than danger coming from the skies, an idyllic suburban family home was the source of terror.

This cult classic is based on the real story of James Herrmann and Lucille Hermann of Long Island, New York in 1958. The Herrmann family reported real poltergeist activity when they moved into a new home, such as bottle caps “popping” off of the bottles at random and bookshelves falling over for no reason. Inviting a priest to bless the house only made matters worse. When Lucille was asked if she had watched The Poltergeist movie, she had a chilling response: “I never saw Poltergeist. I felt I had my own nightmare.” It’s one thing to watch a scary movie; it’s a whole different thing when your actual life is one.

At the time, real human skeletons were cheaper to procure than plastic ones.

In a case of real life imitating art imitating real life, some people consider Poltergeist to be a cursed movie. Heather O’Rourke who played Carol Anne died at just age 12 from complications of a bowel obstruction. Dominique Dunne who played Dana died at age 22 when her ex-boyfriend strangled her to death. Her ex, John Sweeney, served only three years and seven months for her murder. Part of the Poltergeist curse may be due to Steven Spielberg’s insistence on using real human skeletons during filming.

A Killer in the Family (1983)

This movie is based on the Tison v. Arizona case from Arizona in 1978.

This made-for-television movie is based on a true story where a father convinces his three sons to help break him and his cellmate out of prison. They do. Incredibly, at the time inmate’s families were allowed picnics with them. The sons brought a cooler filled with sawed off shotguns and revolvers.

After escaping, things spiral completely out of control, and the prison-break story turns into even more crime, including a killing spree. The real name of the father that started all of this is Gary Tison, and the local Arizona newspaper has an in-depth explanation of his life and crimes.

A Nightmare on Elm Street (1984)

Genocide in Cambodia inspired this frightful monster of dreams.

For casual horror fans, it might come as surprise that this 80s horror-thriller from Wes Craven was inspired by an actual event and a particularly disturbing moment in world history in Southeast Asia after the Vietnam War. After the end of the Cambodian Civil War in the 1970s, the Communist Party of Kampuchea took control of the country and killed over a million people under the rule of Pol Pot. The locations where this genocide was done are known as “The Killing Fields” — and Craven was inspired by a family that escaped them to the United States, but one of their children ended up still having horrible dreams about being murdered.

Wes Craven explains in his own words in a 1999 interview with Robert J. Emery:

The history of A Nightmare on Elm Street is kind of interesting. I read a newspaper article in the LA Times about an immigrant, a recent immigrant, to the United States. A young man who had complained to his parents about severe nightmares. I think they were from Cambodia, and he was assured that nightmares were not that unusual, he shouldn’t be so afraid. He started staying up and refusing to sleep. The family became very concerned, and they sought the help of a doctor. The doctor prescribed sleeping pills. The young man apparently took them, and in the end it turned out he did not—he was taking them and putting them aside. He had a coffee pot in his room after a while to stay awake, and nobody knew quite what to do. At one point, he was downstairs watching television in the middle of the night and he fell asleep. And his family noticed, finally, that he was asleep, and they brought him up to his bed. The whole family went to bed themselves, thinking, “Thank God, finally he’s sleeping.” Then they heard screams an hour later, ran into his room, and he is thrashing in his bed. By the time they got to him, he was dead…

What makes this true story even creepier, and unbearably morbid, is that many of the young men that fled Cambodia during the genocide also experienced the same psychological terror, which was later classified as Sudden Unexplained Nocturnal Death Syndrome (SUNDS). This is likely the newspaper clipping that Craven read in the early 80s.

Child’s Play (1988)

Chucky is a haunted doll rumored to be based on an old folk legend.

Remember that evil — but also kind of comical — killer doll Chucky? That little guy was possibly inspired by a real-life haunted doll, Robert the Doll. In the 1900s a young boy, Eugene Robert Otto, was given a doll. Just like Chucky, the doll ended up terrorizing the child and other children that would inherit it. Now it’s in a museum and advertised as a doll suffering from demonic possession.

The staff where the doll is held in Key West report strange things around it like Robert’s facial expression changes, hearing demonic giggling, and some have even seen Robert put his hand up to the glass.

As you can see, Robert the Doll does not really look like Chucky, but this is the doll where the whole Child’s Play/Chucky horror franchise possibly started. Series creator Don Mancini has never confirmed the rumors, instead referencing killer dolls in movies and on TV like the Zuni fetish doll from Trilogy of Terror (1975) and Talky Tina from The Twilight Zone, as well as the craze surrounding Cabbage Patch Kids, as inspirations. Additionally, David Sloane, author of a book on Robert the Doll, outright refuted the claims that Chucky is based on Robert in an interview for Florida Weekly. Regardless, the eerie parallels make for a fun story.

Dead Ringers (1988)

This movie is based on two famous/rich identical twins that were creepy and suffered mysterious deaths.

Dead Ringers (1988) is a creepy David Cronenberg film is based on two real people: Stewart and Cyril Marcus, identical twin gynecologists who practiced together in New York City. In Cronenberg’s version of the story, the two twins share women, trade places during surgery, and exhibit other creepy behavior. Think of this movie as American Psycho (2001) meets the television Show Nip/Tuck, but with twins. Cronenberg’s version is fictionalized, however, the strange ending where the twins isolate more and more from society and die through what seems to be a drug overdose or barbiturate withdrawal is based on reality. That said, Stewart and Cyril Marcus in real life were bizarre people, and some who knew them say the truth about these twins might be stranger than Cronenberg’s fiction.

The twins practice as renowned gynecologists.

Here is how one woman describes her experience with the twins in real life.

In the summer of 1975, a pair of forty-five-year-old twins, their bodies gaunt and already partially decomposed, were found dead at a fashionable Manhattan address in an apartment littered with decaying chicken parts, rotten fruit, and empty pill bottles. The bodies were those of Cyril and Stewart Marcus, doctors who had apparently died, more or less simultaneously, as the result of a suicide pact.

Like many people, I was shocked by the information. Two things contributed to my astonishment. One was the men’s twinship, the doubleness that had given them a mutual birth date and now a mutual death date as well. Another was the men’s prominence; they had been among New York City’s most well-known obstetrician-gynecologists.

You can read the rest of the story at The Line Up. Here also is the original New York Times article about their death.

The Silence of the Lambs (1991)

Buffalo Bill was based on a real person.

The primary villain in Silence of the Lambs (1991)—Jame “Buffalo Bill” Gumb—was inspired by not only Ed Gein, but also Philadelphia serial killer Gary Heidnik, who lured people in his van, brought them home to murder them, and kept their body parts in his refrigerator. Buffalo Bill was also loosely based on Ted Bundy. Buffalo Bill made clothes out of human skin just like Gein, kept sex slaves in his basement like Heidnik, and lured them using fake plaster casts just like Ted Bundy.

Mugshot of the real life serial killer Gary Heidnik.

The relationship between Clarice Starling and Hannibal Lector is also based in reality. The real life Behavioral Science Unit of the FBI, as seen in the movie and on shows like Criminal Minds and Mindhunter, does exist and the FBI has interviewed serial killers to better understand how their minds work. One inspiration for the relationship is Bob Keppel, an FBI agent who interviewed Ted Bundy in the hopes he could help with the search for the Green River killer. The character of Jack Crawford in The Silence of the Lambs is based on John Douglas, the original “mindhunter” himself.

Fire in the Sky (1993)

Fire in the Sky: a disturbingly real UFO encounter.

Fire in the Sky (1993) is based on, not inspired by, a story in Arizona from the mid-1970s that sounds unbelievable, but was corroborated by several sources. You can find all the details in a book by Travis Walton that explains his encounter with a UFO in 1975. He and about a half-dozen other members of a road crew were dazzled by a yellow light in the sky that upon further examination was a UFO. When the object struck Travis with a light beam and appeared to kill him, the other members fled.

Instead of being killed, though, Travis was discovered five days later—naked, shaking, and a dozen pounds lighter. He claims to have been taken aboard the spaceship.

Disturbingly, all the other members of the road crew—who, returning to town without Travis, were initially suspected of murdering Travis and concocting this story to save themselves—passed polygraph tests.

The Untold Story (1993)

The Untold Story was followed by two unrelated sequels. The Untold Story 2 (1998) is not based on true events, but The Untold Story 3 (1999) does contain elements of true crimes.

On August 4 1985, ten people, all members of the family of a man named Zheng Lin, were stabbed and strangled to death inside a Chinese restaurant in Macau. Lin owned the restaurant, called the Eight Immortals, and he owed a significant gambling debt to a man who had fled Hong Kong years prior because of another gambling related murder. The killer, Huang Zhiheng, claimed the Zheng Lin and his family had left the country, and he reopened the Eight Immortals restaurant just a few days after the murders. Zhiheng ran the business for months before police finally arrested him. Media coverage of the horrific crime and its aftermath gave rise to an urban legend in which people claimed that Zhiheng used the bodies of the Lin family in the pork buns sold at the restaurant.

In 1993, highly acclaimed actor Anthony Wong starred in The Untold Story (1993), a movie based on the Eight Immortals murders. Wong plays Wong Chi Hang (an alternate spelling of Huang Zhiheng) as a creepy and deranged man with a terrifying temper. The movie seems to depict the killings rather accurately, getting the basic details on screen while sensationalizing the story with disturbing violence and a whole lot of gore. The movie also focuses on the team of police investigating the murders. The antics of the police add quite a lot of humor to the film which makes the violence feel even more unnerving.

Scream (1996)

The opening scene mirrors the conversation that inspired Kevin Williamson to write the script.

Scream isn’t based on a pair of high school killers tormenting their classmates, but it is based on a true story. In August 1990 the city of Gainesville, Florida went into a hysteria as a serial killer committed a series of especially gruesome murders over the course of four days. The Gainesville Ripper was eventually caught and revealed to be a man named Danny Rolling who also murdered a family in Shreveport, LA.

In 1995, writer and struggling actor Kevin Williamson was housesitting in Los Angeles when he caught an episode of the tabloid news show Turning Point about the Ripper. Alone in an unfamiliar home, Williamson tried to distract himself by calling a friend. Their conversation turned to horror and which scary movies they liked best. Williamson hung up the phone and wrote 18 pages about a woman talking on the phone with a killer about scary movies. That became the opening scene of Scream.

The Mothman Prophecies (2002)

The director admits that it the film was really more inspired by true events than depicting actual historical things that happened.

The marketing for The Mothman Prophecies heavily emphasized that the film was based on true events. How real was it, though? Particularly given this is a movie about a mysterious creature that make phone calls and can predict the future?

Well, there really is an urban legend about a being called the Mothman that is told in Point Pleasant, West Virginia. However, no actual evidence proves that this paranormal entity exists. According to folklore, the Mothman is a humanoid creature with glowing red eyes and a 10-foot wingspan. It was first seen in Point Pleasant on November 15, 1966. After a local bridge collapsed on December 15, 1967, killing 46 people, the Mothman sightings ceased.

In 1975 John Keel popularized the Mothman for the rest of the world in his book The Mothman Prophecies. This book is the basis for the 2002 film.

Open Water (2003)

The actors filmed the move in the Bahamas and used real sharks, whereas Jaws (1975) used a mechanical shark.

Shark movies are a dime a dozen, but Open Water is a unique shark-attack movie because it is inspired by a real story and two real people, Thomas Joseph Lonergan and Eileen Cassidy Lonergan. The married couple were on a scuba-diving excursion off Cairns in Australia. The tour company made a mistake and left without them, leaving the couple to fend for themselves in the open water. The couple was never found, and their cause of death is still unknown. They could have suffered a shark attack, which is how this film sees it.

Watch a clip and see real sharks circle the actors.

Speaking of real things, all the sharks used in Open Water were real, and the actors interacted with real sharks in all scenes. As National Geographic noted, while we have a shark fear frenzy in the media, there really aren’t that many actual shark events. There is a sequel Open Water 2: Adrift that claims to be inspired by real events, but it’s not; it was based on the short story “Adrift” by Japanese author Koji Suzuki.

The Exorcism of Emily Rose (2005)

The Exorcism of Emily Rose is inspired by the actual story of Anneliese Michel.

This story of an exorcism is inspired by real events that happened to Anneliese Michel, a young German woman who died of dehydration and malnutrition after a period of about 10 months during which 67 exorcisms were performed on her. Tragically, it is most likely Anneliese Michel was only experiencing mental health issues.

Anneliese was born in Germany in 1952 into a devoutly Catholic household. She was diagnosed with depression and epileptic psychosis at age 16 in 1968 and was unsuccessfully treated in psychiatric institutions. By 1972, she was suicidal. The next year, The Exorcist came out.

Anneliese experienced seizures and hallucinations, she growled, and she had “violent reactions” to religious objects. Then she started seeing “devil faces” and hearing voices telling her she’d rot in hell. She claimed to be possessed by Lucifer, Cain, Judas, Nero, and Hitler. In 1975, two priests started performing exorcisms on Anneliese. These horrifying sessions were recorded, and you can still listen to audio of them. Finally, after 67 exorcisms, she died of dehydration and malnutrition in 1976 at the age of 24.

Wolf Creek (2005)

Wolf Creek (2005).
The name of the mining site where most of the film takes place at, “Navithalim Mining Co.,” is a reference to real-life killer Ivan Milat (with each name spelled backwards).

Though the script for Wolf Creek (2005) wasn’t initially based on any true stories, writer Greg McLean added elements from real crimes and killers during rewrites. The movie is about a trio of backpackers who try to escape from a serial killer after being taken captive in the Australian Outback. While the events in the film aren’t based on a specific case, a series of murders in New South Wales, Australia serves as a foundation.

Between 1989 and 1993, Ivan Milat killed at least seven (and up to 20) backpackers. One man who escaped Milat, Paul Onions, has stated that Milat picked him up as a hitchhiker, asked him probing questions, then attempted to tie him up at gunpoint. It is likely Milat followed this same pattern with all of his victims before taking them to the deep woods to kill them. Milat’s modus operandi is strikingly similar to the killer in Wolf Creek, Mick Taylor.

Additionally, the character of Mick is partially inspired by another Australian killer, Bradley John Murdoch. In July of 2001, Murdoch stopped a pair of tourists, Peter Falconio and Joanne Lees, who were traveling along the Stuart Highway in Australia. Lees managed to escape after being tied up at gunpoint by Murdoch, but the body of Falconio, who was presumed to have been shot out of sight from Lees, was never found. Just like Milat’s crimes, Murdoch’s crime is echoed in Wolf Creek even though the film is not a direct adaptation of the real events.

The Girl Next Door (2007)

The Girl Next Door is based on a real murder that occurred in October 1965 in Indianapolis, Indiana.

This movie depicts an atrocious true story of child abuse and murder. Here is the real backstory explained:

Sylvia Marie Likens (January 3, 1949 – October 26, 1965) was an American teenager who was tortured and murdered by her caregiver, Gertrude Baniszewski, many of Baniszewski’s children, and several of their neighborhood friends. This abuse incrementally lasted for three months before Likens died from her extensive injuries and malnourishment on October 26 in Indianapolis, Indiana.

The torture and murder of Sylvia Likens is widely regarded by Indiana citizens as the worst crime ever committed in their state and has been described by a senior investigator in the Indianapolis Police Department as the “most sadistic” case he had ever investigated in the 35 years he served with the Indianapolis police.

The movie itself is a somewhat accurate portrayal of what happened and is very difficult to watch, though it is of course highly dramatized. For more information on what happened here after you watch the movie, consider reading John Dean’s nonfiction book House of Evil: The Indiana Torture Slaying, which goes into more detail about this case of true crime.

Black Water (2007)

Full trailer for this swampy animal horror film based on a real event.

Black Water (2007) is a creature feature based on a real-life animal attack in Australia. Through suspenseful storytelling, set in the mangrove swamps of northern Australia, the movie gives a dramatic retelling of a crocodile attack. A British newspaper describes the actual event the movie is based on thusly: “It began as a fun day out quad-biking in the Australian outback. But it ended in disaster – with one young man killed by a crocodile and his two friends perched all night in a tree while the predator circled below.” Creepy stuff, aye?

The Strangers (2008)

The strangers wore masks, unlike Bertino’s inspiration.

Writer/director Bryan Bertino says he was inspired to write The Strangers based on a creepy childhood experience where someone came to the door and asked for someone who didn’t live there (similar to the “Is Tamara home?” scene in the movie). Later, Bryan learned that several homes in his neighborhood were robbed and he believes he talked to someone who was casing his home. Bertino says elements of the Manson family murders were also the basis of his script, especially the idea of people wanting to murder strangers “for no reason.”

Vacancy (2007)

The couple discovers they are in a trap.

Vacancy (2008) follows an unhappy couple as they stop at a dilapidated roadside motel in the middle of nowhere. While the story of discovering the motel owner is part of a snuff film ring is totally made up on not based on any particular real-life case, there is a real story of a motel owner who created crawlspaces in the ceiling above the rooms for him to watch his guests. Famous journalist Gay Talese published a letter from such a motel owner who said he spied on his guests for over 15 years.

The Haunting in Connecticut (2009)

The family performs a séance to try to understand why their home is haunted.

Supposedly based on the “real life” Snedeker haunting in Southington, Connecticut, Ed and Lorraine Warren say the house used to be a mortuary and the former owners were necromaniacs. Carmen Snedekker has told the story of her family’s time in a haunted house on the TV show A Haunting and Paranormal Witness. However, others say that the Warrens were grifters who made up stories to sell books.

Like the real story, the trouble in the movie starts when a family moves into a new home, but pretty much everything in this haunted house movie is fictional. The home’s current owners say there is no evidence it was ever used as a mortuary or a funeral home, and they haven’t experienced anything paranormal at all. In fact, they say the worst thing about the house is the trespassers who try to get close to see “ghosts” from the movies.

The Haunting in Connecticut 2 (2013)

The Haunting in Connecticut 2 (2013).
A girl has visions of her home’s violent history.

A standalone sequel to The Haunting in Connecticut, The Haunting in Connecticut 2 (2013) is actually about a haunting at the Wyrick house in Ellerslie, Georgia. After moving into a new home in rural Georgia, a girl begins to have visions of the property’s gruesome past. Later, they learn their home was once part of the Underground Railroad.

The Sacrament (2013)

The Sacrament (2013).
Based on Jim Jones, the cult’s leader is called “Father.”

Ti West wrote and directed this found footage movie that is a fictionalized version of a VICE documentary gone wrong. Two journalists and their photographer friend travel to do a story on a remote religious cult named Eden Parish. While the film is set in the present day, it is based on the Jonestown massacre in 1978 in which 909 members of the Peoples Temple Agricultural Project died along with United States Congressman Leo Ryan at the direction of cult leader Jim Jones.

Like Jonestown, the major plot point is the cult member’s inability to leave Eden Parish both because of the remoteness of its location and because of pressure from cult leaders. The presence of the journalists drives the paranoid cult leader to initiate a mass suicide by way of drinks mixed with cyanide. Armed men shoot members who refuse to commit suicide.

The Conjuring (2013)

Real paranormal investigators look into a home haunting.

Ed and Lorraine Warren were a pair of paranormal investigators who consulted on the Amityville Horror case. They also attached themselves to this other real-life case that involved an allegedly haunted farmhouse in Rhode Island that was occupied by the Perron family. To this day, Lorraine Warren insists the haunting was real:

The things that went on there were just so incredibly frightening. It still affects me to talk about it today.

Andrea Perron, the oldest of five girls, later came forward to say that The Conjuring took some liberties with what actually happened, but that she had personally encountered a demon called Bathsheba:

Whoever the spirit was, she perceived herself to be mistress of the house and she resented the competition my mother posed for that position.

As it turns out, a woman named Bathsheba Sherman had lived in the house in the mid-1800s. What are the odds?

Annabelle (2014)

Annabelle’s opening scene alludes to the Manson Family and the Tate-LaBianca murders.

Following the success of The Conjuring (2013), another movie based on Ed and Lorraine Warren’s paranormal investigations was made. In real life Ed and Lorraine did investigate a haunted doll named Annabelle, and the doll became a famous draw to the couple’s now-closed occult museum. However, the story told in the Annabelle movie is almost a prequel to the “real” story of a nursing student and her roommate who were terrorized by a Raggedy Ann doll they named Annabelle and is also lightly inspired by the Manson family.

You can read the full origin story of Annabelle here.

The Conjuring 2 (2016)

One girl in particular is singled out by the poltergeist.

This Conjuring film is based on one of the most famous hauntings of all time, the Enfield Poltergeist. The Enfield case occurred when a single mother and her four children moved into a welfare house in England. Two of her daughters began experiencing paranormal activity after using a ouija board in the home.

This “based on a true story” movie is interesting because within the film, disproven aspects of the haunting are addressed with the children characters saying that the hauntings were real but they exaggerated parts of it in order to be taken seriously and receive help.

My Friend Dahmer (2017)

This biographical horror film tells the story of serial killer Jeffrey Dahmer.

This odd autobiographical film is based on a 2012 graphic novel by a cartoonist named John “Derf” Backderf. Backderf knew Jeffrey Dahmer in high school and goaded him to perform a series of pranks that were half-done in friendship and half-done as bullying. It details how Jeffrey’s mind fell apart and he lapsed into severe alcoholism after his parents got divorced. And it ends with Jeffrey picking up a hitchhiker and asked him if he wanted to drink a few beers—this wound up being his first real-life murder victim.

Extremely Wicked, Shockingly Evil and Vile (2019)

Zac Efron plays Ted Bundy in this movie.

This Netflix Original tells the story of one of America’s most horrific serial killers, Ted Bundy. The film, which was written by Michael Werwie, uses the memoir of Ted Bundy’s longtime girlfriend, Elizabeth Kendall, as its primary source material. That book is called The Phantom Prince: My Life with Ted Bundy, and you can buy it on Amazon to give the film more context on what is dramatized and what is real. It also includes chilling photos of Elizabeth and her daughter’s life with Ted. The movie is quite disturbing and does a good job of showing what it would be like to be a young single mother involved with a predator like Ted Bundy.

The Conjuring 3: The Devil Made Me Do It (2021)

The trial in the movie was resolved in a similar fashion to the real-life trial.

This movie is about a famous case the Warrens consulted on which was the first time someone tried to create a defense based on demonic possession in U.S. history. After the Glatzel family moved into a new house, they began to experience a haunting. During an exorcism, family friend Arne “Cheyenne” Johnson asked the demon to possess him, rather than the 8-year-old boy who was being afflicted. Months later Johnson murdered his landlord in a crime he claims not to remember.

Things Heard & Seen (2021)

A murder trial relating to the real-life case that inspired Things Seen & Heard is set for late 2022.

This Netflix original stars Amanda Seyfried as an artist who abandons New York City in the 70s in favor of an idyllic country town so her husband can teach at a local community college. Not only is the script based on a best-selling book, All Things Cease to Appear by Elizabeth Brundage, but that book is also based on a true story. Author Elizabeth Brundage wrote it when she, much like Seyfried’s character, moved to upstate New York from the city. In her small town, Brundage discovered the story of a former resident named Cathleen Krauseneck. Cathleen was a 29-year-old mother who stayed home to care for her to a 3-year-old girl while her husband worked to support the family. Her husband says he came home from work all day and discovered an axe buried in his wife’s head, meaning their 3-year-old was alone all day with the body.
