Being on stage a lot is quite physical.

I have the embarrassing thing where often if you're watching a film, you kind of go through the emotions and the thought stages that your character went through, but you sort of do it with Tourette's. So I end up often crying when I'm crying, and looking angry when I'm looking angry, so it's pretty ugly.

I never really think about my gender, first and foremost - until a door is closed to you. Until you can see a parallel opportunity with a man in a similar place in his career and you think, That opportunity is not open to me or my fellow actresses. That's interesting.

At the moment there are 1 in 8 people who have no access to clear drinking water, about a billion people worldwide, which can make you feel quite overwhelmed.

People talk about the golden age of Hollywood because of how women were lit then. You could be Joan Crawford and Bette Davis and work well into your 50s, because you were lit and made into a goddess. Now, with everything being sort of gritty, women have this sense of their use-by date.

Sometimes I think it's so good not to win those things. And, anyway, who wants to peak when they're 28?

You can only desire something that you've already had in your life.
