Keira Knightley is currently filming her latest movie in which she plays bounty hunter Domino Harvey.

Domino, nicknamed 'Betsy', was the daughter of actor Lawrence Harvey and Vogue model Paulene Stone, who roamed about the streets of LA hunting down criminals. Her main targets were drug dealers, but she also tracked down a few murderers to add a bit of variety.

Knightley is enjoying the role and is currently undergoing martial arts training in order to play her part to the full.

When Knightley has finished filming on this venture, she will move on to the sequel to Pirates of the Caribbean.
