Posing at the Anna Karenina premiere Los Angeles - Arabstoday British starlet Keira Knightley opted for big statement at the film\'s Los Angeles premiere of  Anna Karenina. The English actress looked stunning in a strapless mint green ball gown with blue embroidery as she posed outside the Arclight Theatre. Her hair was kept in a simple up-do, her lips pretty in pink and her eyes donned a feline look which we loved. Joining the 27-year-old at the screening was fiance, Klaxons keyboardist James Righton, the film\'s director Joe Wright, who she previously worked with on Pride & Prejudice and co-stars Domhnall Gleeson and Alicia Vikander
