With most movies made with the intention to attract audiences, it's no wonder why many filmmakers choose the most gripping and entertaining stories to tell. One thing studios do to get the audience's attention is to make a big deal about the fact that a film is based on actual events, which usually creates a lot of buzz. However, some other films that are also true don't publicize that information. This makes it all the more shocking when you learn after a little research that a movie wasn't entirely based in fiction. Take a look at some of these popular films and see if you knew they were inspired by true events.
