I will tell you that when I was heavy, people would say to me - and it was such a backhanded compliment - they would say, 'You've got such a beautiful face,' in the way of, like, 'Oh, isn't it a shame that from the neck down you're questionable.'

When I think about somebody like Keira Knightley, whom I don't particularly know, I see somebody who is working hard, really trying to challenge herself and make smart choices in spite of people criticising her size and performances.

God, my brain really goes to mush when I'm pregnant.

I don't have parts of my body that I hate or would like to trade for somebody else's or wish I could surgically adjust into some fantasy version of what they are.

I do endless chopping and preparing things. I really find that relaxing. I do a lot of thinking as I am chopping and cooking.

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.

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.
