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.

Amongst my friends, I am known as the most cynical person they know - I'm incredibly cynical. I don't believe in God, I don't believe in the supernatural, I don't believe in anything! And I'm terribly cynical, and somehow or other, all three of my films and much of my television work has been rather sentimental, and 'heartwarming'.

It seems to me that romantic comedies used to be about falling in love, but in recent years they've really become just comedies where the love story is only there as a spine to hang the jokes on.

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'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.

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.
