Keira Knightley at Anna Karenina Premiere in LA | Pictures

Keira Knightley donned an Erdem gown, complete with a train, to premiere Anna Karenina in LA last night. She was accompanied on the red carpet by director Joe Wright and costars Alicia Vikander, in Rodarte, and Domhnall Gleeson. After the screening, Keira changed into a sexy dress with cutouts to celebrate at a Champagne-filled afterparty. Also on hand to toast Anna Karenina was Russell Brand, who mingled with Joe, Keira, and other cast members.

Keira has been busy promoting her latest project, and last week we caught up with her at the NYC premiere. Keira spoke about playing Anna, saying the legendary character from Leo Tolstoy's novel is one "you might hate." Aside from the big screen, Keira can also be found on the cover of this month's Allure. Keira posed topless for the magazine, and inside the issue, gets candid about issues involving her career, body image, and feminism.
