Knightley scared of nasty role

Keira Knightley was terrified when she was offered the role of Cecilia in the big screen adaptation of Ian McEwan's bestseller Atonement - because she thinks the character may turn the public against her.

The Oscar-nominated actress, 21, is set to star opposite Narnia star James McAvoy in the movie, which is helmed by Knightley's Pride and Prejudice director Joe Wright.
