The Amityville Horror is based on a popular novel by Jay Anson with a little longer title, "The Amityville Horror - A True Story". The true story is, at this point, well known to be fictitious, but it did give the public quite a rise for a while. In the story, a young man ends up shooting his parents and sibling while they slept in the middle of the night for reasons even he couldn't begin to explain. The horrific events shocked the small town, but the house was still deemed worthy for sale. Enter the Lutz family, who buy the house because it is going for a relatively cheaper rate than if it didn't have the malevolent stigma, but they can't pass up the price. However, weird things start happening, starting with the fact that the preacher (Rod Steiger,) who comes to bless the house is scared out of his wits, soon after suffering from an unknown ailment he feels has been inflicted by the evil within the house. The Lutz family themselves start exhibiting weird behavior themselves, with the father, George (James Brolin), always feeling cold, and having little motivation to do anything more than chop wood for the fire. Doors and windows open and close, the daughter starts talking to an imaginary (?) friend, and the dog starts sniffing around the cellar trying to dig up something only he knows is there.
