Keira Knightley: Freeze up on set? Not anymore!
New Anna Karenina stills featuring Keira Knightley
The third collaboration of Academy Award nominee Keira Knightley with acclaimed director Joe Wright, following the award-winning box office successes Pride & Prejudice and Atonement, is a bold, theatrical new vision of the epic love story, adapted from Leo Tolstoy’s timeless novel by Academy Award winner Tom Stoppard (Shakespeare in Love). The story powerfully explores the capacity for love that surges through the human heart. As Anna (Knightley) questions her happiness and marriage, change comes to surround her. Also starring Matthew Macfadyen, Jude Law, and Aaron Taylor-Johnson.
