KEIRA KNIGHTLEY

After playing a bounty hunter in Domino, Knightley trades her bullet belt for a corset in Pride and Prejudice. But even though she doesn't have to wield a machine gun, Knightley, 20, says she was "terrified" of taking the role of Elizabeth Bennet in the period drama. "She is one of my favorite characters. I said to my agents, 'Don't let me ruin that character, please!'  And they just went, 'Oh, you wuss, shut up.' Which is good, I'm glad they did."
