“The Faces” was the original title of the film.
A real farmhouse was the actual location of the house’s exterior in the movie – it was perfect with its long winding road, garage, and a forest.
The house in the film was specifically designed to give off that homey atmosphere so the audience can connect more to the movie. The interior was built on a sound stage.
In the opening scene, the houses shown each resemble a specific house from various horror movies such as the Amityville Horror, Halloween, etc.
In the movie, the song Mama Tried can be repeatedly heard all throughout the movie. It is a hit song by Merle Haggard and the Strangers.
