Los Angeles is not a town full of airheads. There's a great deal of wonderful energy there.

When I am asked about influences, I always say I bow down to Fred Astaire, because when you look at him dancing you never look at his extremities, do you? You look at his centre. What you never see is the hours of work that went into the routines, you just see the breathtaking spirit and freedom.

I'm a lot less serious than people think, it's probably because the way my face is put together.

I have a photograph at home of Fred Astaire from the knees down with his feet crossed. It's kind of inspiring because it reminds me his feet were bleeding at the end of rehearsals. Yet when you watch him, all you see is freedom. It's a reminder of what the job is about in general, not just being in musicals.

I never talk about 'Harry Potter' because I think that would rob children of something that's private to them. I think too many things get explained, so I hate talking about it.

My idea of a real treat is Magic Mountain without standing in line.

I think the thing about film is, as it gets proved by a lot of young filmmakers now, that the medium will just go on reinventing itself, and so you just hope to be a part of that and not a part of some kind of endless regurgitation or 'Here I am doing what you know I do' kind of thing.
