The Amityville Horror
"For God's sake, GET OUT!" was the ad campaign for the 1979 shocker The Amityville Horror. The film was based on the allegedly true story of the luckless Lutz family, who move lock, stock, and barrel into a new home, only to find that it is possessed by the demonic spirits of its previous owners. Variations of the Seven Deadly Plagues emanate from virtually every household fixture, while other forms of otherworldly mischief are suffered by the Lutz children. Enter kindly Father Delaney (Rod Steiger), who does his utmost to exorcise the house. The Amityville Horror was frequently greeted with laughs from its first-run audiences, especially after it was discovered that the "actual" events depicted in the film (based on a book by Jay Anson) were complete fabrications.
