Which True Crime Story Was So Freaky, They Made A Movie About It?

Sometimes real life is the true horror.

More often than not, we'll watch a disturbing or scary movie and be like, "Well, at least something like that could never happen in real life." But unfortunately, my friends....THAT'S NOT ALWAYS THE CASE.

Dimension Films

So, we'd like to know: what's a true crime you know of that was so freaky, they made a horror movie about it? For example, maybe you learned that An American Crime starring Elliot Page is actually based on the story of Sylvia Likens, who was brutally tortured and ultimately murdered by her caregiver in Indiana in 1965.

Showtime

Or maybe you watched The Strangers and innocently decided to look up a little more info about the movie, only to find out it's semi-based on the Keddie Cabin Murders, where a 14-year-old girl came home from a sleepover to see her mother, brother, and friend murdered on the living room floor.

Rogue Pictures

Or maybe you love recommending The Stanford Prison Experiment, because it's based on — you guessed it — the real-life Stanford Prison Experiment that took place in 1971.
