I can only do it if there's humour, wit, comedy and drama. If you can get audiences laughing and then suddenly turn them to tears... it's a weird way of making a living making people cry, but I think it's very exciting to be able to send audiences on a rollercoaster ride.

In the States everyone aspires to be middle class. It's so engrained into the American psyche: As long as you work hard you're going to be rich some day. The history of Britain is that if you're born working class, you're going to stay there, although that is changing.

In England we only make films about the working class or the aristocracy.

I think your 20s are the hardest part of life. I mean, everyone goes on about how hard it is to be a teenager, but actually I think it’s tougher to be in your 20s because you’re expected to be a grownup and expected to earn your own living and be successful and I think you feel like a kid still.

I think films about men are often about characters who don't want to express their feelings. You're supposed to kind of admire them for not expressing their feelings. And I feel that's a bit dull. Women's stories often have stronger emotional content, which I enjoy doing. What I really love doing is mixing that with humor.

I can't find anything wrong with Ashton Kutcher. I think he's great. It's odd that in America there's a very mixed reaction to him. I think those that have only seen him on 'Punk'd' or 'That 70s Show' get him wrong. There's much more to him than those characters or that persona he plays in those shows.
