I worked with John Maybury on The Jacket and I think he's an extraordinary film-maker. I read the first drafts of this piece when I was working on The Jacket, and we'd so fallen in love with him that we thought he was the only person that should direct this! We wrote poems for him, we sent him champagne and cakes. Four years later he finally read it.

You already feel unsure of yourself, and then you see your worst fears in print. It really knocked me - which is why, I think, I was working, working, working, because I was trying to run away from the fact that I thought I couldn't do it.

I think sometimes it's sort of easier to be playing a role based on a real person because there's quite often a lot more information, you're not making it up, it's there in books, it's there in research form. But really the questions you ask about the character, and why people behave, and where they come, and how they've ended up in the places they've ended up are the same.

My upbringing is why I am the person I am today. I have very wise parents.

The celebrity thing's completely crazy. I think I just have to move away or give it up altogether. I couldn't have kids in the situation I'm in now. But I could just do something else. That's probably what's going to happen. I made a decision very recently that I want a life instead.

I'm ... incredibly open with my mates. Or even people I just meet.

I wasn't allowed to do commercials. I wasn't allowed to do TV series. I wasn't allowed to do soaps or basically anything that would mean I missed too much school.
