Top 50 scariest movies of all time

Memorable quote: I admire its purity. A survivor, unclouded by conscience, remorse, or delusions of morality.
Scare factor: Maybe its just a little indigestion. Yeah, that must be it. Oh wait, whats that bulge violently erupting from my torso? If serving as the incubator for a killing machine from outer space doesnt scare you, then just wait until it grows up, and hides in the shadows of your spaceship, and picks off your crew one-by-one. Luckily, you have a cyborg on your side. Right?
