I don’t know what happened through the ’80s, ’90s, and ’00s that took feminism off the table, that made it something that women weren’t supposed to identify with and were supposed to be ashamed of. Feminism is about the fight for equality between the sexes, with equal respect, equal pay, and equal opportunity. At the moment we are still a long way off that.

You live with a writer [a mother], and you grow up with their words, their kind of fantasies, and I'd pretty much seen every single one of her plays, and been in a lot of rehearsal rooms, so it felt very natural and easy. It was lovely to get an opportunity to do that professionally as well.

In the movie, you're moving, you have personality, you don't have to be great looking.

I've had my body manipulated so many different times for so many different reasons, whether it's paparazzi photographers or for film posters.

Half of my mum's family is Welsh. I remember when I was a kid she used to read to me, and witches and wizards in books always had a Welsh accent, so I guess I took it from that really.

I have no idea whether I am completely sane. I don't think anybody is. I see the world through my eyes. It's sometimes a strange world. I hope I don't hurt people. You hope not to hurt yourself too much, either. Maybe that's the definition of keeping yourself in check?

I've had my body manipulated so many different times for so many different reasons, whether it's paparazzi photographers or for film posters. The topless Interview shoot was one of the ones where I said: 'OK, I'm fine doing the topless shot so long as you don't make them any bigger or retouch.' Because it does feel important to say it really doesn't matter what shape you are. I think women's bodies are a battleground, and photography is partly to blame. Our society is so photographic now, it becomes more difficult to see all of those different varieties of shape.
