I think I matured quite early, but what that does mean is I have moments of complete immaturity. When I come home, I don't want to be an actor. I just want to be a kid. I barely even know what money is.

I think I've learned a lot working with actors as experienced as Nicole Kidman and Daniel Craig. They taught me that whatever happens during a take, you should just carry on. Don't ever stop until the director tells you to stop.

Daniel Radcliffe told me once that you should always keep the people around you that you know are going to tell you the truth.

I still havent got over the fact that I wont be the only person seeing the film. Im used to watching home videos of when I was little, singing Barbie Girl and stuff, and nobody sees them except the family. Now, there will be loads of people going to see The Golden Compass. At least, we hope they will.

If you don't have your friends, you start to go a bit mad. That's why in the future I don't want to be constantly acting, going from one film to another. I just think it would be so very lonely to be away from your friends and family for so long and no proper kind of routine.

Math is my favorite subject. It's the universal language. I like the fact that wherever you go in the whole world, two plus two will still be four.

You grow up a lot on set, but it doesn't change you.
