Keira Knightley has revealed that she hates watching her own movies.

The Pride and Prejudice star admits that she is too critical of her performances, and finds them too painful to watch.

"I'm my biggest critic by a mile. You give me the worst review ever and times it by about 10 - that's where I put myself. It's a huge fault," Breakingnews.ie quotes the actress as saying.

"It's really difficult to go back to a performance that I'd now like to do completely differently. Suddenly you think: 'Oh, I wish I hadn't done that and I wish she had been like this."
