Healthy love, I always think, is... wanting the person you love to be more of themselves. And I think for a parent that's a challenge, because you have to let a baby spread its wings.

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.

When I started drama school, theatre was the main draw. I never had any movie star notions. Not that there were family ties to the theatre, either.

I just would like to keep going. If I kept getting the kind of work that I've been getting for the last 20 years for the next 20, I'd be a bloody Dame of the British Empire. I'd be so happy.

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.

I am very lucky. I have known wonderful romantic love in my life but to actually see this little creature and find him to be the most beautiful creature in the world. I know all mothers and fathers feel that way.

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.
