47. The Amityville Horror (1979)
Memorable quote: Get out - get out!
Scare factor: This movie uses a staple of effective scares: based on true events. Whether or not you believe the Lutz familys account of what happened in the Long Island manse, it's hard not to jump at the bumps in the night. The lesson here: Never move into a house where a murder occurred. We know, seems like common sense.
