I eat healthily, I do ballet and exercise, and I'm toned and tight, but I take up space, and I don't aspire to anorexia.

You're in this heightened emotional state from the beginning of the play. It's like when you first have your heart broken.

I think if I'd been born ten years earlier when Ma was at the height of 'Avengers' fame, it would have been a different kettle of fish altogether, but she was very much a ma first and an actress second for my formative years.

I suppose I'm what you'd called a character actress, so, often, my characters are quite extreme.

I had been kind of quite porky and happy at boarding school and not self-conscious at all; then, suddenly, I found myself in auditions being examined, and it made me angry.

I fell upon Jenny Saville's work and loved these great big pieces she was painting, celebrating all things flesh and woman, and with great big Simone Beauvoir quotations written in mirror writing so you had to look at yourself in the pictures to read them.

I teach kids to read on a Saturday for this charity called Real Action. It's a voluntary school because lots of the kids around my area of London are from immigrant families and need extra help with reading.

I find the idea that some kids go into acting because of their parents butt-clenchingly embarrassing. I've gone out of my way to prove myself as a separate being. I don't want to be seen as a subset of someone else.

I love radio interviews; it's all about multitasking and, like all good women, I can do that.

I can't think of anything better than being considered a poster girl for intelligent women.
