8 Great Teachers from Hell

From movies.go.com here is a countdown of 8 of the most hellish teachers ever to appear on film. Not to spoil the whole thing for you, but Professor Snape, as portrayed by the luscious Alan Rickman, is Number 3!

They smirk, they snipe, they curdle your blood. Sometimes, they even put the moves on you (scandalous!). But, at least up there on the screen, classrooms wouldn't be any fun without these twisted teachers.
