The filmmakers of "Pride & Prejudice" reunite for a new movie, based on the award-winning best-selling 2002 novel Atonement, which is a classic British romance that spans several decades. Fledgling writer Briony Tallis, as a 13-year-old, irrevocably changes the course of several lives when she accuses her older sister's ("Pride & Prejudice" Academy Award nominee Keira Knightley) lover (James McAvoy) of a crime he did not commit.
