Horror Movies Based on True Stories

The Conjuring The Birds The Strangers — Everett (3)

Over the years, audiences have been frightened by the varied horror films onscreen, and, while after some jump scares, these audiences can be reminded it’s only a film. However, things can take a dark turn when it’s discovered the stories are actually based on real-life events.

Whether being terrorized by a knife-wielding killer or possessed by a demonic spirit, a variety of real-life crimes and events acted as inspiration for filmmakers and screenwriters who brought scary tales to life onscreen.

From the 2013 film The Conjuring to Alfred Hitchcock’s The Birds, The Hollywood Reporter takes a look at 25 frightening films based on actual events.
