I went to America on holiday when I was 17 and, before I knew it, I'd been signed up by an agency and had these obligations I didn't understand, but which I couldn't say no to. This industry chose me. But I did choose to make it fulfilling.

For me, just being on the cover of a magazine wasn't enough. I began to think, what value is there in doing something in which you have no creative input?

I've always found it very difficult to understand the laws as far as nudity in America - how some things are pornographic and some things are not pornographic. It's against the law to go topless on the beach, but you can go buy a gun. That just seems so absurd to me.

For 15 years, I've been playing the same character - which is myself - and I'm bored with 'myself'.

I choose movies, I never choose roles. I look at the script. I look at the director. I look at the other actors - and then the role.

If I have a choice between putting my kids to bed and going to a party, I'll put my kids to bed. If I have a choice of going to a restaurant or having friends round, I'll have friends round. Every time.

I used to wear heels because I wanted to show people I wasn't ashamed of being tall. But I don't wear them any more because you don't have to wear heels to be beautiful. I can't even remember the last time I wore heels.
