She got her start with relatively small roles such as that of the "decoy queen" Padme in 1999's "Star Wars Episode 1: The Phantom Menace" and as the bride whose wedding starts the action in 2002's "Love, Actually."
Knightley won leading lady status in 2003 with "Pirates of the Caribbean: The Curse of the Black Pear." It's a role she will repeat in two sequels.
She stepped into the elegant world of "Pride & Prejudice" from a very different scene, having just played the lead role of a model-turned-bounty hunter in "Domino."
