Because of the person I am I won't be knocked down — ever. They can say I'm fat, I'm thin, I'm whatever, and I'll never stop. I just won't. I've got too much to do. I've too much to be happy about.

I love the routine. I love getting up in the morning and getting breakfast and packing lunches and doing the school run. Those things are really important to me. Because I think that those small but key moments are crucial for a kid.

Having been here before and lost to be here and win, I've got to tell you, winning is really a lot better than losing. Really a lot better.

Playing Juliet in Heavenly Creatures changed my life, and the role of Clementine in Eternal Sunshine of the Spotless Mind opened many new doors creatively.

I danced a lot when I was younger, and I've always had decent, shapely legs and thought it's now or never. I mean, when you're pushing 40, are you really going to wander around in a dress that's midthigh length?

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.

It's my chance to challenge myself to the fullest, which is one of the great joys about my job... I love it when a character requires me to look less than my red-carpet best. It's more fun playing a character that requires you to look like dog s - t.
