Well, I'd never done an animated movie before, which is why I was so excited about doing it. It was one of the little boxes as an actor that I wanted to tick off. I wanted to do an animated film. So, after my mum got over the fact that I was never going to play Shrek's sister, this was the nearest I was going to get!

I know what I look like. I'm not a babe who's automatically going to be the leading-lady type. I think I would always be cast as the friend. I probably tend to look crap more often than I look good. I like messing around and pulling funny faces and doing funny walks.

I wanted to live where I could pop to the bar that Humphrey Bogart took Lauren Bacall to, or the little restaurant where Charlie Chaplin had a booth.

I don't even think places like the National Youth Theatre (NYT) are necessarily about wanting to be an actor when you grow up. They're about meeting people from different backgrounds and different religions and different cultures, and mixing with people that you wouldn't ordinarily meet.

I was on my own, living in Los Angeles, and I didn't know my way around, so I thought I'd walk everywhere. Well, that certainly got me noticed. Any woman who walks any distance at all is automatically regarded as a hooker!

I think we should be proud of the fact that our face has got lines, because at least that means we have lived.

I only do children's films now! I think when you go to LA some people feel you've defected a little bit and that's not really the case. Ideally, I would love to work here and to work in America. That's in an ideal world. In fact, I came back to Britain recently to do an ITV1 drama that will be out in April for a couple of months! But I'm flying back to LA to do a pilot season. So, to work in both places is great.
