Keira Knightley, from the 2007 film Atonement.
A picture was taken from the scene when Robbie Turner (James McAvoy) was being arrested by the police. Cecilia Tallis (Keira Knightley) ran towards him to whisper something in his ear. The picture was edited to remove Robbie from it. You could go here to watch the scene and click on the picture to see its full version.
