The Strangers is a horror movie that was released in 2008. The screenplay was written and directed by Bryan Bertino, who drew inspiration from real-life crimes and his own experiences. The movie is based on two real-life events: the multiple-homicide Manson family Tate murders and a series of break-ins that occurred in Bertinos neighborhood as a child). According to Bertino, the movie is primarily based on three alternate true stories, including several notorious murders. The Manson murders and the Keddie Cabin Murders are two of the real-life crimes that inspired the movie. Bertinos childhood experience of a stranger coming to his door while he was alone also influenced the movie. While the couple in the movie is not based on real people by the same name that was murdered, the movie is inspired by disturbing real-life stories.
