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.

It's obvious to say you can't please everybody and there are always going to be people who are going to say, I just don't like you. There's nothing I can do about that. I'm aware, probably much more aware than my harshest critic, of what my own problems are with my acting ability. I'm very, very critical of myself, and I don't ever want to not be.

I've got a lot of experience with anorexia - my grandmother and great-grandmother suffered from it, and I had a lot of friends at school who suffered from it. I know it's not something to be taken lightly and I don't.

The thing about great fictional characters from literature, and the reason that they're constantly turned into characters in movies, is that they completely speak to what makes people human. They're full of flaws as much as they are full of heroics. I think the reason that people love them and hate them so much is because, in some way, they always see a mirror of themselves in them, and you can always understand them on some level. Sometimes it's a terrifyingly dark mirror that's held up.
