Bigger films are more difficult because the number of people is so huge.

I don't quite understand what Tolstoy's actual personal view of Anna is - whether he likes her or hates her, whether she's the heroine or the antiheroine.

I totally agree. I hate knowing too much when I'm going to the cinema and watching as a viewer. I don't want to know that the actor has just gone through a divorce. I don't want to know that the person is an alcoholic. It just gets in the way of my pleasure of watching the character on the screen.

Humans who see something different than them want to hate it and tear it down. Britain had a government policy that allowed prejudice to destroy someone's life, and today there is still homophobia at home and elsewhere, like Russia or Greece. It's still a relevant discussion. While women have it better than the 1940s or '50s, sexism is still prevalent.

I see the world through my eyes. It's sometimes a strange world.

You already feel unsure of yourself, and then you see your worst fears in print. It really knocked me - which is why, I think, I was working, working, working, because I was trying to run away from the fact that I thought I couldn't do it.

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.
