Steve Carell and Keira Knightley teamed up on the set of Seeking a Friend for the End of the World today in LA. The dark comedy, which also costars Adam Brody and is being directed by his girlfriend, Lorene Scafaria, just started filming this week. Keira headed back to the states to get to work on the new project after playing bridesmaid in her brother Caleb's wedding late last month in Glasgow. She parted ways with her longtime real-life love, Rupert Friend, late last year but has a new leading man on screen in Steve. The movie features their characters as a star-crossed couple who find each other on the verge of the apocalypse. Steve recently exited The Office and also has Crazy Stupid Love coming out this Summer. Seeking a Friend for the End of the World also marks Keira's return to film following a stint on stage in London in The Children's Hour, a play that costarred Elisabeth Moss. The Coco Mademoiselle spokesmodel focused on that production and her role as the face of Chanel's perfumes for much of the year before signing on to star opposite funnyman Steve.
