10 Horror Movies You Didn't Know Were Based On True Stories

Silent House follows Elizabeth Olsen as Sarah, a young woman helping her uncle and father clean up their family's run-down Victorian country house. The three soon come under attack by a group of mystery assailants, forcing Sarah to fight back.

This version of the film is based on the original Uruguayan version, directed by Gustavo Hernández. Hernández was inspired by a real-life story that took place in the 1940s, where two mutilated bodies and several disturbing photographs were found inside a country home. In an unusual move, he intended his film to act as the last 80 minutes before that double murder took place.

So Silent House isn't based on something that actually happened - it's based on what Hernández imagined had happened, with the director essentially creating the events that led to two bloody corpses and a bunch of grim photos.
