Mostly, I'm drawn to great characters and great worlds that use weird things for their language - whether it's dance, whether it's pop music with Justin Bieber, or whether it's magic.

There is always this thing of will you get too old for your part? But people are playing a lot younger than they actually are in real life. I don't think it's as big an issue as a lot of people are making it out to be.

I've learnt a lot about certain things but you also learn through your own experience.

I'm an atheist, but I'm very relaxed about it. I don't preach my atheism, but I have a huge amount of respect for people like Richard Dawkins who do.

Working hard is important. But there is something that matters even more, believing in yourself.

As much as I would love to be a person that goes to parties and has a couple of drinks and has a nice time - that doesn't work for me. I do that very unsuccessfully. I'd just rather sit at home and read, or go out to dinner with someone, or talk to someone I love, or talk to somebody that makes me laugh.

I sort of try to read the books when they come out impartially and not make up my mind, but the fact is when I was reading the sixth, 'Harry Potter And The Half-Blood Prince', there were bits in there where I was going, 'God, I would love to do that because it's so good'.
