Keira Knightley

Movie News - Keira Knightley embraces dark roles and says she enjoys doing ''darker'' movies.

The 27-year-old actress - who has shown the dark side of her personality in movies including 'A Dangerous Method' and 'Anna Karenina' - admits she is always drawn to how challenging a film is for her, but what format that takes often changes.

She said: ''I try to do pieces that are as challenging to me as possible. Now one day that could be a romantic comedy or the Hollywood thriller that I'm currently doing ('Jack Ryan'), but lately they have taken a much more European, kind of a darker tilt.

''But it's been more about what I wanted to explore, the worlds I wanted to explore.''

However, no matter what she does, Keira makes an effort not to engage with critics too much, and instead has a close circle of people she trusts.

She told Deadline.com: ''I think you have to be careful where you take your notes from. So I've got about three or four people I talk to, and I pretty much ignore the rest.

''In watching yourself, it's very difficult to remove vanity - you think, 'God, I look disgusting'. At the end of the day, you can't listen to everyone's opinion or else you'd be very, very confused.''
