The popular image that Hollywood is ruined by difficult prima donna actors is nonsense. They're certainly very nice to directors. I can't say the same about producers, who I found difficult, paranoid, and certifiably insane, mostly.

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 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 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.

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.
