I didn't really know anything about Margot Fonteyn. I'd never really been a ballet child, so I had no idea what an incredibly huge icon she was, not just in terms of a creative icon - she was also a style icon. I had no idea she was up there with Audrey Hepburn and Jackie Onassis in terms of that kind of image.

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.

I only went along to youth theatre with a friend when I was young to try to make myself a bit more sociable. But the whole thing was quite sore; it really hurt me trying to get into drama school. It was a world I knew nothing about - it was very middle class; all that usual stuff. But I was young, determined, and I just went for it.

I was very lucky in that my parents were very broad-minded. Because they had come from another country and hadn't been able to fulfill their dreams, they wanted me to be more of myself, if you know what I mean.

I think age is sometimes just a number. But it's a real joy. Young actors don't come with any of the baggage that we load ourselves up with. They're not worried about their profile, they're not worried about how good they look, or all the nonsense. They just tell the story and ask: "What happens in this scene?" Well, I'll do that then. And professionally it's good for you because it means that you're forced to do the same thing, and that's always a good thing.

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 sometimes think it's like a weird elastic band. The more tragic your work is, the quicker you snap back. There's a catharsis in telling a miserable old tale; you get rid of demons.
