Acting is invigorating. But I don't analyse it too much. It's like a dog smelling where it's going to do its toilet in the morning.

To be honest, I'm scared to death of rollercoaster rides.

It's always fun to do the fight sequences and then to complete them, because some of them are quite complicated - with guns and so on - and there's always things that can go wrong. It's fun to shoot those things because we rehearse them very strenuously. It's fun to shoot them, and fun to know they're finished, that they're in the can so to speak.

I have friends who have daughters and there's times I think I'm glad I have boys instead of girls.

We're all always acting. You need to be able to sit in silence and not beat up on yourself. It's hard to say to yourself, 'You are human. Welcome to the human race.'

I love working with children and this young boy, Thomas Sangster, is quite a remarkable young actor. He raises your game, you know. He certainly raised mine.

You just get this profound feeling of instability . . . the Earth isn't stable anymore and then it passes and it becomes more infrequent, but I still get it sometimes.
