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

Some people say Dylan Thomas mischievous, he's a child, and other people say he's quite demonic. I don't think we should dictate about him, if that's your view of him, that's wonderful, but it's great to know that other people think differently.

I have no idea whether I am completely sane. I don't think anybody is. I see the world through my eyes. It's sometimes a strange world. I hope I don't hurt people. You hope not to hurt yourself too much, either. Maybe that's the definition of keeping yourself in check?

I think you've got to take the risks. There's no point playing it safe, because either you'll get bored or the audiences will get bored. Sometimes, you're going to make mistakes, and that's fine, but you have to take the risks. I think Pirates is one of the prime examples of that with Johnny Depp's performance, and part of the reason that people love it so much is that you watch it and go, "Gutsy, really gutsy!"

It's all about perfection, isn't it?

Everybody can take a good picture. Everybody is interesting. Everyone has an interesting face. Some people are more difficult or more nervous or more tired. When you do a movie, you have action, you're talking, you're moving. You don't see the camera. Taking a picture with a photographer, you don't talk, it's more difficult than in a movie for your body to relax, to be yourself.

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.
