Johnny Depp  turns 51 this week — we can't believe it either — and his birthday has given us a great reason to take stock of his many movie roles.

Some looks are scary, some are sexy, and some are just plain strange. See them all here, and then reflect on how your crush on him  has had just as many weird phases.
