The Movie: 'The Amityville Horror' (1979)
The Scene: The Lutzes try to make a new start in their relationship by moving into a house with distinctive, quarter moon windows and a tragic past (modeled after a book by Jay Anson -- based on a true story). A boy murdered his entire family there and even though George Lutz (James Brolin) tells his wife, "Houses don't have memories," he turns out to be dead wrong.
Not long after they move in, Father Delaney (Rod Steiger) arrives at the Lutz's in order to bless the house per the missus' request (Margot Kidder). When he arrives no one's home, but he invites himself in anyway to perform his priestly duties. Father Delaney hears strange giggling upstairs and enters one of the bedrooms to check things out. Of course, this is where he decides to set up camp for the blessing ritual. A plague of flies have other plans for the priest and start to swarm him, not long after the door mysteriously slams shut on its own. A gallon of sweat and some scenery chewing later, Delaney watches in disbelief as the door slowly opens again and a demonic voice is heard demanding the priest leave immediately. It only takes two words from this malevolent, unseen force to make Father Delaney run: "Get out!"
