Written by Horror stories take on a life of their own when you know they are based on real-life events. Suddenly, what appears to be fictional will leave you haunted at night, making you double-check whether you saw something paranormal out of the corner of your eye. Some of the best films in horror cinema are inspired by true stories, remaining timeless for their great retelling of events.
Watching a truly effective horror movie is enough to crawl into your nightmares, and if you know they happened to somebody in the real world, that’s enough to rethink the next abandoned house you see. This list covers the top 10 horror movies of all time that are based on true stories, ranked based on how scary the events were portrayed in the film.
10. The Exorcism of Emily Rose (2005)

The Exorcism of Emily Rose is based on the true story of Anneliese Michel in one of the most controversial courtroom cases in history. Her life and death were studied and put on trial, telling everyone the tragic events of an exorcism gone wrong. The protagonist of this film exhibits a huge emotional range, so while you do empathize with her condition, you’re equally terrified.
The film truly has terrifying moments like the 3 AM devil hour scene, along with the reality-questioning nature of a possessed individual. While the film does a good job of questioning faith, the interspersed court scenes can come off a bit drab compared to the actual horror, which is why it’s ranked last on this list.
9. Poltergeist (1982)

Poltergeist scared an entire generation born in the ’80s, inspired by the legendary 1958 haunting of a family home in Seaford, Long Island. The family was tortured by flying furniture and objects mysteriously breaking, with the lore suggesting the house was built on a disturbed burial ground. The film’s priest delivers some of the best horror scenes in cinema history, similar to Sinners’ “invite me inside” horror.
Poltergeist has visually frightening scenes, such as the iconic girl in front of the TV. The practical effects were used very well, making the movie semi-timeless but also dated given the advancements in haunted house filmmaking. Unfortunately, the performances and practical effects just don’t hold up, placing this film at #9 on the list.
8. The Lighthouse (2019)

The Lighthouse is inspired by a real 1801 lighthouse tragedy in Wales. Two Welsh lighthouse keepers were marooned on an island, and after one of them died, the other was driven mad from isolation with a rotting corpse. There’s a lot to praise when it comes to the cinematography of this flick, and even more so when it comes to the dedication by its protagonists to shoot in gruelling conditions.
The movie effectively combines cosmic horror with phenomenal acting from its two-person cast. We were so convinced that they were driven mad by each other’s company, and every tidbit of myth and folklore added turned this into a larger-than-life horror story told in glorious black-and-white. With a low rank of #8, The Lighthouse faces shortcomings with regard to its vague and ambiguous third act.
7. The Texas Chainsaw Massacre (1974)

Routinely making the rounds on some of the scariest grindhouse horrors ever made, The Texas Chainsaw Massacre is based on the notorious real-life serial killer, Ed Gein. The man has a myth surrounding him, trapping and torturing victims in rural Wisconsin. To date, this movie has seen multiple iterations, spawning franchises and video games, but none come close to the horror of the original.
Texas Chainsaw Massacre gave us a new kind of slasher subgenre in the horror realm, along with introducing the iconic Leatherface mask, used as a horrific disguise when lynching victims. It’s one of the essential horror movies for your collection, where the use of practical effects involving blood and skin is enough to induce nausea. However, the film ranks at #7 and not higher, as its repeated brutality becomes a double-edged sword for many viewers who find the extreme horror unsuitable for their taste.
6. Scream (1996)

The iconic masked serial killer comes from Scream, inspired by the real-life 1990 killer Danny Rolling. Known as the “Gainesville Ripper,” the story revolves around the murder of college students in Gainesville through playful tormenting. What’s especially scary about Scream is the constant sense of not having any character to particularly root for, making this a creepy experience on the whole.
Scream has a lasting impact on cinema, effectively becoming the blueprint for so many slasher flicks that followed. The iconic “serial killer chasing a woman” trope comes directly from this, and the real horror that anyone, even your friend, could be the killer was enough to terrify audiences worldwide. However, the movie sits at #6 because while it is self-aware and smart, the ending turned out to be a little underwhelming.
5. A Nightmare on Elm Street (1984)

The serial killer that can murder you in your dreams comes in the form of A Nightmare on Elm Street, based on 1970s and 1980s reports of people who mysteriously died in their sleep after intense fear and nightmares. What was more weird is that it was mostly Southeast Asian refugees who were affected by nightmares, forcing themselves to stay awake out of fear.
Taking on a life of its own, Freddy Krueger became the manifestation of nightmares. We can say it’s one of the perfect horror films for Halloween. The movie ranks at #5 for effectively taking this real-life story and turning it into some of the most terrifying scenes in horror history. A scene that comes to mind is the well-executed VFX of Freddy scratching his way through a wall to kill his victim. The movie acts as a perfect bridge between the ones below and above, mostly staying here for its over-the-top performances.
4. Zodiac (2007)
A still from Zodiac | Paramount Pictures
The Zodiac Killer is a real-life serial killer who terrorized Northern California in the ’60s and ’70s. Based on the direct true-crime horrors committed by the killer, whose real identity is still unconfirmed, Zodiac makes him an omnipresent murderer capable of shutting down an entire city just by the various clues he would leave. Zodiac is one of the murkiest and bleakest thrillers ever made, eventually turning into a cult classic despite bombing at the box office.
Coming in at #4, the movie does a solid job of creating the killer’s elusive lore, blending horror elements with a police procedural. You’ll feel constantly tense, wondering when he’ll strike next, just like the citizens of Northern California. The only gripe people have had with the film is its pacing, given the long runtime.
3. The Conjuring (2013)

Ingrained into everyone’s memory is the “Based on a True Story” opening credit from The Conjuring, a movie that successfully scared the living daylights out of moviegoers with its relentless jump scares. Based on the true stories from real-life paranormal investigators Ed and Lorraine Warren, the movie follows the Perron family from Rhode Island in 1971. From the blindfold clapping to Bathsheba appearing on top of the wardrobe, every scene either builds up a horror or shows one.
The movie blazes into the top 3 for telling a classic haunted house story in the best way possible. Its three-act structure does not bore you at any point, escalating the stakes beyond the house itself. With images from the real world strewn into the credits of the film, it’s hard to discredit the horrors. The movie does not rank higher simply because the other two are in a league of their own.
2. The Birds (1963)
A still from The Birds | Universal Pictures
Alfred Hitchcock successfully made us afraid of birds with this 1963 classic that does not feel dated in any way. Birds was inspired by the true story of a 1961 bird attack in California, where birds started crashing into buildings and biting residents while swarming the town of Capitola. It’s a wonder how Hitchcock managed to convince studios to let him shoot this project, but the truth is that he is known for pushing the boundaries of filmmaking.
The movie sits at a high #2 for employing actual birds in the movie, despite them ending up terrorizing the cast. Feeling like a rare-but-plausible scenario, the movie proves that if birds do decide to terrorize us, we’re quite defenseless in the face of these tiny creatures. Birds would take the #1 spot if not for:
1. The Exorcist (1973)
The Exorcist changed cinema forever, let alone horror. Based on the real-life story of the 1949 exorcism of 14-year-old Roland Doe, the movie switches him out for a young girl, but retains the horrors of being possessed by a demon. Guttural voices, repelled by sacred items and demonology lore, became horror staples after this flick retold the events of what happened. Unfortunately, the cast involved suffered a lot of trauma during the production, ranging from deaths to freak fires.
The movie easily takes the coveted #1 spot for still being the best horror movie of all time, despite being released decades ago. The extent of influence The Exorcist has had on pop culture, and the idea of churches being involved in exorcisms and possessions, threw a light on more cases around the world where these horrors lurk.
