Robert Pattinson's next film, Cosmopolis, is getting a leading lady shake-up prior to filming. Keira Knightley is set to star in the film opposite Pattinson, replacing original actress Marion Cotillard, due to Cotillard's pregnancy. Knightley will play the wife of Pattinson's character in the slightly futuristic Manhattan drama. Pattinson should have no trouble getting into character as the onscreen husband of fellow Brit Knightley, since he's currently getting in lots of movie marriage practice.
