Ah, my dad's whistle. On holidays when I was a kid, we would all be off in the rock pools along the beach. When it came time to go, we'd hear the whistle and we'd all come running. Like dogs!

It's very tempting to have a nanny and live in a gated community and have a chef - I'd love to have a few dinners cooked for me. But I don't want that for my children. When they're older, if people say to them, 'Did you have a chef?' I want them to be shocked by the question.

By nature, I'm a very positive person, and because I'm happy in myself, and in my life, and I've got a great husband, and beautiful children, and I have a job that I love that calls for a certain amount of emotional expression, I get to realise a lot of my dreams and aspirations.

I'd rather do theater and British films than move to L.A. in hopes of getting small roles in American films.

For my own children, I do want for them to look back and remember that it was me in the kitchen, that I was doing the packed lunches, that we were there on the school run, that we did take a bus. I want them to remember those things, because those are the things that I remember from my own childhood and that have been incredibly important to me.

My dad was an actor, and my older sister is an actress, and so I very much remember thinking, "Well, of course I'll do that as well." But I never imagined myself as an actor who would be in films. I always only thought of myself being in a play or a musical and maybe the odd episode of [U.K. '80s TV drama] Casualty. My backup plan was to do something with children, to start a nursery school or work with underprivileged kids. And I still dream of maybe doing that in some way. I've always got children in my house, always.

He's brilliant. At first, I thought, 'Oh, is he going to be Hollywood stud-like?' But he's a really kind, wonderful person. He said to me one day early in the making of the movie, 'You know, I was kind of worried about you'. He thought I was going to be a perfect skin, which I am certainly not. It didn't take long for Leo to crack and see who I really am, and we became very close. but, I must say, he is absolutely gorgeous.
