Well this isn't very timely. But still, another bit of inquisitive Friday fun!
Although there are 8549027869056725 sites out there that ask and answer the same thing -- i.e., the shower scene in Psycho -- a (sort of) friend writes to SFist asking:
What do you think is the scariest scene in movie history?
Eh, why not? East: the scene in Cinderella where her stepsisters tear apart her pink gown right before the ball. Awful. Just terrible. Walt's rape fantasies spilled over into his work this time, with gruesome results. (Watch it here. If you dare.)
And yours?
