Knightley: I sought lighter role
Keira Knightley has revealed she wanted to do a comedy because the usual roles she plays are so dark.
The 27-year-old actress - who most recently played a mental patient in David Cronenberg's A Dangerous Method - is set to appear opposite US comedian Steve Carell in new film Seeking A Friend For The End Of The World.
Keira, who vamps it up in tight leather and heavy make-up for the cover of Interview magazine's April issue, revealed: "I love Steve Carell; he is one of the most loveliest men on earth.
"It was my attempt, given that my work seems to be going from dark, to dark, to darker, to do something a little bit light. And then my friend said, 'What's it about?' And I said, 'The end of the world.' So I've managed to go a tiny bit lighter, but it is about the end of everything."
The Pirates Of The Caribbean star has also been busy filming a new big-screen adaptation of Anna Karenina with director Joe Wright.
She told Interview: "It's very exciting. We're right in the middle of it. It's totally different than this; it's a very, very stylised version of it, and she's a tricky character.
"I remember reading it as a teenager and just seeing the romance of it. Then all of a sudden I read it over the summer, and thought, 'Wow. Sometimes Tolstoy actually hates her quite a lot. Is she the heroine or the anti-heroine?'
"It's an interesting thing, with all of us, we're sort of grappling with those ideas. You don't want to simplify anything, because it should be an exploration of somebody who breaks their own moral code, and what happens when you break your own moral code. It's really interesting, and fingers crossed it will work."
