I see myself doing Harry Potter films as long as I'm enjoying it and as long as they are going to challenge me as an actor. I want to be an actor - it's my aspiration - so I want to do other films. I want to write something and I want to direct something!

I think Harry Potter's very important. Every opportunity I will get for the rest of my life, I would not have got if it wasn't for Harry Potter. And it would be height of ingratitude if I was ever anything but proud to be associated with these films.

I was very sad to leave Harry Potter but equally there will be an element of excitement about the idea that a script might come in and I don't have to go: "I'm sorry, I'm kind of busy for the next four years." The idea of that is quite exciting.

I don't [believe in God]. I have a problem with religion or anything else that says, 'We have all the answers,' because there's no such thing as 'the answers.' We're complex. We change our minds on issues all the time. Religion leaves no room for human complexity.

There's no blueprint for where I should be. I see myself as a young, good actor who still has a lot to learn. There's nobody at any point in their career who is the finished article.

Because I'm short and slim, I can identify with somebody who's an unlikely fit for something and desperately wants to be part of it.

One of the things that I cannot fathom is young actors who will not audition and won't read.
