Sure, Halloween was weeks ago, but it's never the wrong time to think about scary movies, so here is retroCRUSH's 100 Scariest Movie Scenes.

In particular, I agree 100% with:

#97 - Frankenstein
#96 - Blue Velvet
#93 - Creepshow
#89 - The Blair Witch Project
#72 - Poltergeist II
#64 - Poltergeist
#62 - When a Stranger Calls
#52 - The Ring
#51 - Jaws
#50 - An American Werewolf in London (this scene should be much higher than 50)
#34 - The Ring
#23 - A Nightmare on Elm Street
#20 - Jaws
#17 - Misery
#11 - Psycho
#9 - The Exorcist III (Maybe the scariest scene ever)
#4 - Alien
