10 Horror Movies Based on Totally Terrifying True Stories

Not every horror movie is a work of pure fiction.

Hollywood takes some liberties, sure, but these real life horror stories gave screenwriters chilling ideas. Although some of these movies turned out to be more frightening than others, there’s no doubt that the actual incidents that inspired each would be enough to send any of us running for the hills.

As long as those hills don't have eyes, naturally.

It turns out that Hannibal Lecter isn’t just the product of someone’s sick, overactive imagination–he’s based on a Mexican surgeon named Alfredo Ballí Treviño who killed and mutilated his friend, his lover, and (allegedly) several hitchhikers.

If you hadn’t heard of the Zodiac Killer, who murdered people in the 60s and 70s and then sent taunting notes to the police, you probably looked him up during the 2016 Presidential election. The cases were never solved, but this movie is a look at one reporter’s attempt to crack the case.

A small boy received Robert the Doll in the early 1900s only to find out the seemingly innocent gift was a voodoo doll. Though there’s no proof that it’s possessed by the spirit of a serial killer (or anything else for that matter), it was the inspiration for Chucky and Charles Lee Ray.

The filmmakers of The Strangers point to a variety of real-life home invasion cases as source material for their chilling flick. One particularly grisly case rumored to have served as inspiration? The Keddie Murders of 1981, which remain unsolved to this day. In 1981, four people were brutally murdered in the Keddie cabins in the California woods. The movie does diverge from the actual case, as it follows a couple rather than a family. The couple in the film is stalked and terrorized in a remote location before being murdered at dawn.
