Vote up the scariest movies with the creepiest real-life stories behind them.

Not all the movies on this list are, strictly speaking, crime films. However, these movies all have their roots in real transgressions or bizarre cases , such as The Exorcism of Emily Rose , in which priests and a girl's parents may have been responsible for her demise.

Some of the films draw from news stories, and others are adaptations of novels based on notorious killers . While Freddy Krueger wasn’t actually a real person who went after teenagers in their sleep, the premise of A Nightmare on Elm Street was based on the story of a perfectly healthy young Cambodian refugee who was having terrible nightmares before finally passing in his sleep. Infamous slayer and grave robber Ed Gein inspired some of the most iconic film characters in the history cinema: Norman Bates from Psycho , Buffalo Bill from The Silence of the Lambs , and Leatherface from The Texas Chainsaw Massacre .

Some of the films based on true stories from this list are more factual than others. For example, Dahmer and Monster are not horror films inspired by actual murders, they are biopics of the real culprits. While the films take a poetic license, they tell the stories of Jeffrey Dahmer’s and Aileen Wuornos’s lives. Check out these 20 films inspired by true stories.
