What's The Scariest Movie That's Actually Based On A True Story?

Boo!

It's October, and that means it's time to get SPOOKY.

And one of the scariest things in the world is when real-life events are so freaking creepy that they get turned into movies.

Maybe you're a true horror fan and know that The Strangers was based off of the unsolved Keddie murders that happened in a cabin in the woods in California.

Perhaps you discovered that A Nightmare on Elm Street was inspired by a news story where men literally died of fright because of how scary their dreams were.

Or maybe you learned that the first Scream was inspired by the Gainesville Ripper, a knife-wielding murderer who'd kill people in their own apartments.

It's time to get spooky, so use the DropBox below to tell us your favorite scary movies that are actually based on true events!
