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.

In some ways, you get to find your voice better in [a sequel] because you have to define how you're doing it differently.

I think I'm a tiny bit like Harry 'cos I'd like to have an owl. Yeah, that's the tiny bit, actually.

When I get into trouble at school I'd like to take an invisibility cloak, drape it over me and sneak out the door. Or I'd like to have a 3 headed-dog because then no one would argue with me.

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 don't really care about how I look.

For ages, in my lunch hours, I would just go round and choreograph fight scenes. For fun. So now I'm very good at being thrown around. I bounce, in the words of my friends.
