I am incredibly passionate about my life, I am absolutely unable to hide any emotion. If I wrote a book, I'd have to call it 'P is for Passion'. I don't go in for anything halfway. My feelings about things are instant, on the spot. And my heart is always, always on my sleeve.

I look like people that walk down the street. I don't have perfect boobs, I don't have zero cellulite - of course I don't - and I'm curvy. If that is something that makes women feel empowered in any way, that's great.

When I think about somebody like Keira Knightley, whom I don't particularly know, I see somebody who is working hard, really trying to challenge herself and make smart choices in spite of people criticising her size and performances.

Ultimately, you just have one life. You never know unless you try. And you never get anywhere unless you ask.

Yeah, acting is very difficult. As much as I love it, and the challenge of it, I'm so often just terrified by it.

After Titanic it would have been completely foolish for me to go and try and top that. I'm an English girl, I've always loved England, I've never felt the desire to leave it for any particular reason. And whilst I'm ambitious and care very much about what I do, I'm not competitive. I also don't want to act every day of my life. () So it was important to me after Titanic to just remind myself of why it was that I was acting in the first place, which is of course because I love it.

At some stage I'm going to have to say, 'Right, that's it. I'm stopping for a bit'.
