I'm not making films for middle aged journalists, who are mostly men. I make films that hopefully entertain people, where they can learn something about life.

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.

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.

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.

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

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.

I think the first rule of comedy is that it has to be funny and I find a lot of the broad comedy which is sent to me, painfully unfunny.
