25 Best Horror Movies Based on True Stories
The Amityville Horror (1979)
Horror fans were captivated when Stuart Rosenberg released The Amityville Horror, a chilling movie based on a true story. Set in Long Island, the tale begins with the grisly mass murder at 112 Ocean Avenue. On Nov. 13, 1974, Ronald DeFeo Jr. fatally shot his parents, Louise and Robert Sr., along with his siblings, Dawn, Allison, Marc, and John, leaving an entire family slain. This tragic event laid the foundation for a legend that would go on to haunt the box office and spawn a series of films and books.
When the Lutz family moved into the infamous home in 1975, their 28 days of experiences reportedly included supernatural harassment by malevolent spirits. Stories of hauntings and bizarre occurrences dominated the public imagination, with skeptics debating the claims. Nevertheless, the movie became a surprise hit, remaking the concept of a possessed house for the American middle class. The flick inspired countless sequels, influenced iconic works like Poltergeist and Paranormal Activity, and redefined how real estate could become the backdrop for enduring tales of terror.
The movie’s legacy is inseparable from the cultural fascination with haunted spaces and spooky happenings. Despite sceptics who have long discredited parts of the story, the chilling atmosphere and unsettling narrative continue to captivate audiences. This unique blend of alleged paranormal events, crime, and human fear ensures that The Amityville Horror remains an iconic piece of scary storytelling, proving why it became a landmark in the horror genre.
The Conjuring (2013)
Directed by James Wan, it is inspired by the real-life events involving Ed and Lorraine Warren, a famous pair of paranormal investigators. The film portrays their investigation into the supernatural occurrences at the Perron family’s home in Rhode Island in 1971. This haunted farmhouse, located at 1677 Round Top Road, was said to be plagued by malevolent spirits. The Warrens, who are well known as demonologists, played a key role in the story, although the real-life Perron family had some doubts about their involvement. The Warrens were not originally a part of the family’s experience but were brought in due to the escalating paranormal activity.
The film blends classic horror tropes and jump scares, making it a standout in the genre. Patrick Wilson and Vera Farmiga star as the Warrens, reprising their roles in the sequels, Conjuring 2 (2016) and The Conjuring: The Devil Made Me Do It (2021). The film draws from the Warrens’ previous case and has inspired a broader universe of films, including the Annabelle series. Though the story is based on real-life events, it takes creative liberties for dramatic effect, mixing horror with suspense to create a chilling experience. Roger and Carolyn Perry’s terrifying tale has now become the cornerstone of the horror franchise, captivating audiences worldwide.
The Exorcist (1973)
The 1974 debut of The Exorcist continues to frighten audiences to this day, with its chilling premise based on the real-life case of 14-year-old Roland Doe. In 1994, it was reported that Roland was possessed by a sinister force, leading to a series of exorcisms performed by priests. During the ritual, Roland even ripped off a mattress spring and threw it at one of the priests, an act that left behind red scratches spelling out the name “LOUIS.” The mystery surrounding his possession and the strange circumstances surrounding his case remain a source of fascination for many. It’s a story of grief-stricken parents, a spiritualist aunt, and the use of a Ouija board that spirals into a terrifying experience.
The real-life inspiration for the movie started when Roland, after his aunt’s passing, began experiencing bizarre events, such as water mysteriously dripping from the walls and his bed moving. His family sought the help of Catholic priests like Father E. Albert Hughes, who first tried an exorcism in February 1949. The exorcism was performed in Maryland before Roland was sent to St. Louis for further help from Father Walter H. Halloran and Rev. William Bowdern. After months of rituals, it was reported that the devil had left him. Years later, Roland, whose true identity was Ronald Edwin Hunkeler, became a NASA engineer and helped with the 1969 moon landing, only revealing his true identity after he died in 2020.
The Exorcism of Emily Rose (2005)
The film The Exorcism of Emily Rose is one of the most unsettling horror movies based on true stories, loosely inspired by the real-life tragedy of Anneliese Michel, a young German woman who died after undergoing an exorcism. In 1975, Anneliese began experiencing seizures and hallucinations, which her Catholic parents believed were signs of possession. Seeking help, they turned to two priests, Father Arnold Renz and Father Ernst Alt, who performed over 70 exorcism sessions in an attempt to save her.
Sadly, the young woman succumbed to malnutrition and dehydration, leading to the parents and priests being charged with negligent homicide. Director Scott Derrickson adapted this chilling real-life event into a blend of psychological thriller, demonic horror, and courtroom drama. This real scary movie features a stellar cast including Laura Linney, Campbell Scott, Tom Wilkinson, and Jennifer Carpenter, vividly portraying the harrowing events that unfolded in Bavaria, West Germany.
The story delves into Emily Rose’s suffering from schizophrenia and epilepsy, her belief in possession, and her insistence on exorcism. It also explores the subsequent court case, where faith was debated against facts. All involved were found guilty but received lenient sentences. This harrowing tale, rooted in reality, is a haunting example of the consequences of faith, science, and desperation intertwined.
The Texas Chain Saw Massacre (1974)
Released in 1974, The Texas Chain Saw Massacre quickly became one of the most disturbing horror films ever made. The story is centered around the chainsaw murderer known as Leatherface, a character who is loosely inspired by the life and crimes of the real-life killer Ed Gein. Gein, also known as the Butcher of Plainfield or Plainfield Ghoul, was infamous in the 1950s for exhuming corpses from graveyards and making keepsakes from their bones and skin. This twisted behavior deeply influenced the creation of Leatherface, whose menacing, basement-dwelling presence in the film creates an unforgettable terror.
The film’s original concept draws parallels between serial killer Ed Gein and Leatherface’s chilling acts of killing and wearing faces. Leatherface’s history of wearing women’s clothes only adds to the unsettling atmosphere, echoing Gein’s disturbing habits. Set in the rural Texas landscape, the Chainsaw Massacre is not just about a murderer but also about disturbing imagery and a character that terrorizes a group of unsuspecting travelers.
As the real danger sets in, the audience is forced to witness the gruesome aftermath of Leatherface’s acts, further emphasizing the disturbing nature of this iconic film. The reports from critics and fans alike only add to its legendary status in horror film history, ensuring that the Texas Chainsaw Massacre remains an enduring classic of the genre.
The Strangers (2008)
In 2008, Bryan Bertino’s film The Strangers shocked audiences with its terrifying portrayal of a home invasion. The story is inspired by a combination of real-life violent crimes and murders, including the infamous acts of the Manson Family and the 1981 Keddie Cabin Murders, where four people were brutally killed by three masked assailants in a small California resort town.
Like many other chilling events, this one remained unsolved as the murderers were never apprehended. Bertino’s film combines this grim history with elements of his childhood, recalling how he was once spooked by strangers who knocked on his door while he was home alone. Though the strangers were just thieves in the process of stealing from vacant homes, the unsettling encounter left a lasting mark on him, which he later used as inspiration for the movie.
Recently, it was announced on Sept. 13 that The Strangers would be getting a reboot, with Madelaine Petsch set to star and Renny Harlin directing. The film, produced by Lionsgate, promises to bring fresh tension and terror to a new generation of horror fans. The Strangers continues to be a thrilling example of how real-life events, from Sharon Tate’s tragic death to the Keddie Cabin Murders, can blend into the amalgamation of horror cinema. The fear of being watched by strangers is universal, and this film taps into that unsettling feeling, leaving viewers haunted long after the credits roll.

The Warrens declared the home to be overrun by demons, an experience that profoundly affected the Snedeker family. These real-life events became the inspiration for the chilling movie The Haunting in Connecticut, one of the most actually scary films based on true events.

The couple, tourists visiting Australia’s Great Barrier Reef on Jan. 25, 1998, faced a terrifying and mysterious nightmare.
Though experts debate whether the couple met the same fate as depicted in the film, their disappearance remains unsolved. Filmmaker Chris Kentis crafted a gripping premise inspired by their ordeal, where a couple is stranded in the ocean, vulnerable to relentless sharks. This film is one of the most genuinely scary movies, capturing a primal fear of being abandoned in an endless, hostile sea.
The Lonergans’ tragedy is brought to life with unflinching realism, using real-life sharks and filming in the ocean itself. The tension builds as the characters battle both psychological despair and the constant threat of predators.

Scream (1996)
The 1996 original slasher film Scream redefined the horror genre by blending suspense with self-aware humor. Among the most notable true horror movies based on true stories, this iconic franchise drew inspiration from the chilling Gainesville, Florida, mutilations. These real-life events involved the brutal murders of young people in a local community, creating a sense of terror that shook the area.

Annabelle (2014)
The real-life story of Annabelle is as chilling as any horror movies based on true stories, including the films in The Conjuring franchise, which began in 2013. According to renowned paranormal investigators Ed and Lorraine Warren, the cursed doll, resembling a Raggedy Ann, was gifted to a young nurse. Soon after, a series of mysterious events unfolded, including a traumatic experience involving her boyfriend. Seeking answers, the nurse and her friends, Donna and Angie, contacted a medium, who claimed the doll was inhabited by the spirit of a deceased 7-year-old girl named Annabelle Higgins. Initially thought to be benevolent, the Warrens later revealed that the doll was controlled by a demonic entity seeking a human host.
The Warrens conducted an exorcism and relocated the haunted doll to their Occult Museum in Monroe, Connecticut, locking it in a glass case with a chilling warning: “Positively do not open.” Though the stories surrounding the doll remain unverified, they have inspired generations of horror enthusiasts. With appearances in Annabelle (2014), Annabelle: Creation (2017), and Annabelle Comes Home (2019), the doll’s legend endures, blending unsettling supernatural occurrences with captivating cinematic storytelling. This story remains a cornerstone of horror movies based on true stories.
Borderland (2007)
Borderland is a freaky indie film that stands out among horror movies based on true stories by taking inspiration from real events in the late ’80s on the Mexican border. In Tamaulipas, a group of drug-dealing occultists, known as narcosatanists, carried out ritual human sacrifices. The film, starring Rider Strong and Sean Astin, follows the chilling story of three friends who travel to Mexico to celebrate their college graduation but unknowingly stumble into a dangerous cult. This crime is loosely inspired by the life of Adolfo Constanzo, an American-born serial killer and cult leader, whose dark practices in Mexico City attracted followers and terrorized the region.
Dramatizing the widely publicized abduction and murder of a University of Texas medical student in 1989, Borderland brings horrifying realism to the screen, making it a standout among horror movies based on real life stories.

The film vividly brings this eerie legend to life, making the story even more terrifying as the characters face the overwhelming power of this sinister force.
The Rite (2011)
The Rite is among the most chilling scary movies based on true events, drawing inspiration from the book The Rite: The Making of a Modern Exorcist by Matt Baglio.

On November 5, 1975, Walton, a logger, claimed he was abducted by extraterrestrials while traveling back to Snowflake, Arizona, with his colleagues. According to Walton, he was taken aboard an alien spacecraft, subjected to strange examinations, and then left on the side of an Arizona highway.

Tobe Hooper delivered one of the most iconic horror movies based on true stories with Poltergeist.

The story centers on the Hermann family, who experienced violent hauntings after their home was reportedly built on a Native American burial site. Strange occurrences, such as objects moving on their own and popping bottles, prompted the family to seek help from paranormal investigators.
The infamous Seaford poltergeist case gained national attention when Life Magazine detailed over 70 mysterious incidents between February 3 and March 10, 1958. The eerie events included items like shampoo, bleach, and holy water inexplicably spilling from their containers, and furniture toppling without cause. Despite efforts from a priest, the hauntings escalated, forcing the family to flee. As one of the most enduring true scary films, Poltergeist masterfully combines fact and fiction, creating a cinematic experience that continues to haunt audiences decades later.
A Nightmare on Elm Street (1984)
Wes Craven’s A Nightmare on Elm Street is one of the most iconic horror movies based on true stories, drawing eerie inspiration from a real-life tragedy. The film’s chilling premise stems from the story of a young boy who died in his sleep after suffering terrifying night terrors. The boy’s family, having escaped the horrors of Cambodia’s killing fields, found refuge in the U.S., but his haunting nightmares persisted. Desperate to avoid sleep, he stayed awake for days, only to succumb when he finally gave in to exhaustion.
This tragic incident, combined with reports of 26 young Southeast Asian refugees dying from mysterious nightmares in 1981, became the foundation for Craven’s story. The horrifying idea of nightmares leading to death birthed Freddy Kruger, a killer who preys on victims in their sleep. Released in 1984, the film transformed nightmares into a terrifyingly real experience, cementing Freddy as a cultural icon. As one of the most unsettling true scary films, A Nightmare on Elm Street remains a masterpiece of the genre, turning real-life fears into an unforgettable cinematic horror. Few horror movies about true stories have captured the fragility of the human psyche as effectively as this legendary slasher.
The Birds (1963)
Alfred Hitchcock’s The Birds, released in 1963, is a bizarre and absurd film that still holds growing influence in the horror genre. Inspired by Daphne du Maurier’s short story, the movie centers around a coastal town in California, specifically Capitola, where birds suddenly begin attacking people. This eerie event was inspired by real-life events that took place in 1961.
In Monterey Bay, birds started dive-bombing homes and cars, and their actions became more erratic, causing mania. Scientists later discovered that the strange behavior was due to toxic algae in the birds’ environment, which led to amnesia, disorientation, and even seizures. The cause of this terrifying incident remained unknown at the time, but the real-life inspiration made Hitchcock’s depiction of attacking seagulls and flocks seem all the more menacing.
Despite its goofiness at times, Hitchcock’s film remains an unforgettable piece of cinema. Over time, its influence has grown, though some critics still compare it to other films like The Blob or The Day of the Triffids. Hitchcock’s portrayal of nature turning against man, with birds attacking without reason, seems almost ludicrous when viewed from today’s perspective, but it nonetheless captures the audience’s attention. Researchers reported in 2011 that the strange behavior was caused by toxin-making algae in birds. This discovery further enhanced the enigma surrounding The Birds, demonstrating how life can mimic art in unexpected ways.
Winchester (2018)
The 2018 film Winchester delves into the chilling tale of Sarah Winchester, a story that remains one of the most intriguing horror movies based on true stories. Played by Helen Mirren, Sarah is portrayed as a grieving widow haunted by the spirits of those killed by the Winchester rifle, her late husband’s invention. After the tragic loss of her husband and infant daughter, Sarah relocated to San Jose, California, where she constructed the infamous Winchester Mystery House. This labyrinthine mansion features hundreds of rooms, staircases leading nowhere, and mysterious doors, all said to be part of her effort to appease vengeful spirits.
While the supernatural elements of the story add to its allure, the true scary films inspired by the house also touch on historical truths, such as the aftermath of the 1906 San Francisco earthquake, which led to rapid repairs and bizarre architectural choices. The mansion, with its 160 rooms and countless eccentric features, remains a fascination for ghost hunters and skeptics alike. Few true scary movies capture the blend of myth, mystery, and history as effectively as Winchester, a film that transforms Sarah’s quest for peace into an unforgettable cinematic experience.
Stuck (2007)
The horror movie Stuck brings to life one of the most unsettling real story horror movies ever adapted for the screen. Starring Mena Suvari as Brandi, a young nursing assistant, the film follows her horrifying predicament after a hit-and-run accident. The victim, Gregory Glen Biggs, becomes lodged in her windshield, forcing Brandi into a nightmarish situation as she grapples with what to do next.
This shocking tale is based on the real-life case of Chante Jawan Mallard, a Texan woman whose negligence and attempts to cover up her actions led to tragic consequences. Mallard struck Biggs, a homeless man, leaving him trapped in her vehicle until his eventual death. Her crime resulted in a 50-year prison sentence, making this story as haunting as it is morally complex.
The film blurs the lines between horror and human failing, forcing viewers to confront the darker side of human decision-making. As one of the most gripping real story horror movies, Stuck serves as both a cautionary tale and a disturbing exploration of guilt, desperation, and the consequences of inaction.
Black Water (2007)
A family vacation to the mangroves of Northern Australia takes a terrifying turn when they experience a crocodile attack. What begins as a peaceful trip quickly becomes a fight to survive as the family faces the dangers of the wild. The movie is inspired by real-life events, specifically a 2003 crocodile attack in the area. The film uses a mix of real crocodiles and CGI to create the vicious monsters that terrorize the characters. While the story is based on actual events, it is embellished for dramatic effect in the film.
The marketing of the movie claims it is based on true events, which is partly accurate. The crocodile attack and its aftermath are central to the plot, but the filmmakers took creative liberties to heighten the tension and horror. The combination of real footage and special effects makes for a chilling experience, blending reality with fiction to tell a thrilling and terrifying tale of survival.

In Things Heard & Seen, starring Amanda Seyfried, a Manhattan couple relocates to a historic hamlet, seeking a fresh start. However, their new home harbors dark secrets linked to its sinister past. This eerie tale is one of the compelling horror movies based on true stories, inspired by the 2016 novel All Things Cease to Appear by Elizabeth Brundage.
Brundage drew from alleged supernatural occurrences in a house she and her husband once rented, weaving these unsettling events into the narrative. The scary movie real story explores the couple’s unraveling marriage and the haunting forces lurking in their seemingly tranquil surroundings. As they delve deeper, they uncover chilling truths that blur the line between reality and the supernatural.
Zodiac (2007)
In the 2007 film Zodiac, directed by David Fincher, the story of the Zodiac Killer comes to life through the lens of Robert Graysmith, a political cartoonist played by Jake Gyllenhaal.

Graysmith’s obsession with uncovering the identity of the killer consumed him, leading to a decades-long quest that even impacted his marriage. The movie dives into the still-unsolved case, where new theories about the killings continue to surface.
This masterpiece explores not just the true crime of the Zodiac but the psychological toll it took on those trying to solve the case. Zodiac transports the audience into a realm of mystery and intrigue through re-enacted scenes that vividly depict the haunting slayings. The film explores how the pursuit of truth can consume a person as decades-long obsessions unfold, particularly when the case remains unresolved, with each new theory expanding our understanding of the killer and his victims.
Compliance (2012)
The incident that inspired the indie thriller Compliance revolves around a disturbing prank call made in 2004 by a man posing as a police officer. This chilling event took place at a fast-food restaurant in rural Kentucky, where the employee was manipulated into committing a strip search on her coworker. The humiliation, as part of a series of indignities, sets the stage for a claustrophobic drama directed by Craig Zobel. The film delves deep into the torture and the complex themes of American fealty to authority, revealing how a harmless-sounding phone call spirals into something much darker.
While the film doesn’t include bloodshed or death, it highlights the messed-up nature of the prank call and its devastating effects. By exploring the themes of power and manipulation, Compliance brings to light how authority figures can be used as tools to cause immense humiliation and torture. The series of events that unfold demonstrate just how vulnerable people can be when their trust in authority is manipulated.
Rillington Place (1971)
The Rillington Place film is a harrowing entry among horror movies based on true stories, recounting the grim legacy of London’s notorious serial killer, John Christie. An unassuming postman turned murderer, Christie carried out his horrific crimes in the 1940s and 1950s, strangling eight women, including his wife, in his Notting Hill flat. The film captures the sinister essence of this scary movie real story, immersing viewers in the chilling reality of a man who committed unspeakable acts while blending seamlessly into his community.
Directed by Richard Fleischer, the movie portrays the dark, claustrophobic atmosphere of the infamous flat. Richard Attenborough’s unsettling performance as Christie heightens the tension, making it one of the actually scary horror movies in the true crime genre. The film delves into the psyche of a seemingly ordinary man whose heinous actions left an indelible scar on the history of serial killers, delivering a haunting experience that lingers long after the credits roll.
