Keira Knightley and Jude Law stepped out for the world premiere of Anna Karenina at London's Leichester Square today. Keira got glamorous in a white Chanel Couture gown while Jude posed in a gray suit. Keira popped up overseas after spending much of the Summer in NYC with her fiancé, James Righton. When she wasn't busy strolling the city streets with James, Keira filmed Can a Song Save Your Life? with costars Mark Ruffalo and Adam Levine. Keira's already lined up yet another project — she'll star opposite Chris Pine in the upcoming Jack Ryan. The movie may take Keira back to the Big Apple since production recently started there for Chris.
