I don't think it's that I don't like Sondheim. It's that I find it really... I don't know how to describe it. Doing it is the most extraordinary thing. Because it's like Shakespeare times 100 with singing. It's that satisfying - and that demanding.

The one good thing is that I get a lot more good scripts coming through my letterbox. 'Vera Drake' raised my profile in one way, and then 'Harry Potter' in another.

Agents and producers have to get you into a box to accommodate their limited imaginations.

I don't feel the need for religion. But I went on a yoga retreat last year and I do believe slightly in the karma thing and just being good and true unto yourself. And I slightly believe that you can attract good and bad to you.

Fortunately my career has never been about how I look, it's about how I can be.

I adore Bette Davis and Vivien Leigh, but more because they were good actresses. That’s what makes me interested in them, that they didn’t present themselves as idols; they were just doing their jobs.

Her death has had a huge effect on me. It felt like a big hole appeared on my left side - apparently your left side is your mother - which I thought could never be filled. Now I think what you have to do is fill it with yourself because your mother is part of you. I'm easing into that space, using it and being comforted by it.
