Nothing is more diminishing than trying to control success or hold on to things.

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.

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.

As I get older, I want to draw on my experience to make roles better. I see that in the older women who inspire me - their experience makes them better.

I don't look like Catherine Zeta-Jones, so I don't think Hollywood would be that interested in me, to be honest. I just want nice work.

For actors, being successful is generally getting a job. If you can work a lot, you're really successful. If you work a lot on projects that are interesting and intelligent and great fun to be part of, then you're hugely successful. And I feel hugely successful. I can't believe that I get to be involved with the projects and the people I work with.

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.
