When I was a kid, I wanted to be serious, like Daniel Day-Lewis. No one really dreams of being a comic actor, do they? Now I realise how stupid that is - and it's because comic acting isn't taken seriously enough. It's a discipline. You know instantly - either you're funny and getting the laughs, or you're not.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
