1. John Carpenter's Halloween
    I hear that theme, and immediately I'm ten years old sleeping with the lights on.
  2. Blair Witch Project
    Old hat now, but then? Totally innovative. Spielberg taught us: if you wanna really scare them, don't show them the monster.
  3. The Exorcist
  4. The Exorcist, Part III
    The funniest and scariest movie I've ever seen.
  5. Stanley Kubrick's The Shining
    What THE HELL was with the walrus on the bed?
  6. Se7en
    "John Doe has the upper hand" is the single scariest line I've ever heard.
