Horror movies are great because they are fictional; the killers aren’t real. Once the movie ends, you’re safe. Some of the best horror franchises, in fact, have introduced viewers to beloved killers like Halloween’s Michael Myers and Scream’s Ghostface. They’re fun to watch because they give viewers a jump scare and show us the darkest side of humanity that doesn’t actually exist — or does it?

As it turns out, several fictional movie characters aren’t all that fictional. They are based on real people and real events. From Leatherface to Hannibal Lecter, here are 10 horror movie characters that are based on real people and events.

10 The Texas Chainsaw Massacre — Leatherface

The original Texas Chainsaw Massacre was released in 1974 and is the first of nine film installments. Starring Marilyn Burns, Paul Partain, Edwin Neal, Jim Siedow, and Gunnar Hansen, the film follows a group of friends who fall prey to a family of cannibals on their way to visit an old homestead. The film was marketed as being based on true events to attract a wider audience. While the plot is largely fictional, the character of Leatherface was inspired by the crimes of murderer Ed Gein.

Gein, also known as the Butcher of Plainfield, was an American murderer and body snatcher. He gained notoriety in 1957 when authorities discovered that he stole corpses from local graveyards and made trophies, keepsakes, and furniture from their skin and bones. Gein also confessed to killing two women in 1954 and 1957.
