You want to have enough of a profile to be able to do all the work you can, but at the same time you want to have your own space. But there are a lot of actors who achieve it, a lot of movie stars even, people like Emily Watson and Cate Blanchett. They seem to be able to carry on with their lives and still produce wonderful, high-profile work.

I think creative people need to do a bit of, you know, tuning into every radio station - you just do, otherwise you don't know much about other people. You kind of have to learn a bit about yourself so you can work out how we all behave and why we do the things we do.

The level of sacrifice in the world of dancing is incredibly intense, that work ethic if nothing else - get up, go to class, rehearsal, performance, get up, go to class - that's your life, and it's like that for a finite time, usually.

I'm a right pain in the hole for my agent. I won't take certain parts if I think they're offensive or banal. For instance, I won't do a film if I think it's full of violence for violence's sake, or a television drama if I don't think it's intelligent writing.

I think American drama is at its best when it takes the domestic and makes it epic, like a Greek tragedy in the front room.

In theatre, there's the director, the writer, and below them the actor. In film, it's the actors who are most important. That goes against the grain for me.

I suppose it's whether you want to be a famous person, or whether you want to be an actor. You have to decide what your priorities are. Great actor, huge star. Sometimes, the two walk hand in hand. Most of the time, they don't.
