In Joe Wright's Come Back To Me (Atonement), Keira Knightley plays Cecilia, a well-bred young woman who falls in love with the governess's son, played by James McAvoy. The romantic tension between the two protagonists soars to electrify viewers during the memorable scene where the two lovers meet in the library. In addition to Cecilia and Robbie, there is a third character in this scene that takes all the space on the screen: the emerald green dress worn by Keira Knightley.
