There's an incredible comfort level that I have on film sets because it's where I've grown up.

I always saw Michael Gambon wearing madly psychedelic socks, and I always thought that's it is one of the few areas where men can really express colour and have a bit of a dandyish quality to their outfit.

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.

My job to make sure that thing is kick-ass - takes the mold, jumps on it, throws glitter all over it, smashes it, kicks it around, and drops the mic. If we don't do that, then we deserve not to have a hit.

I have described myself as being 'gently eccentric.'

I absolutely don't relate to being beaten down my whole life - I had amazing opportunities at a young age - but there is still in many, many people's minds the notion that I'll never be able to escape Harry Potter.

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.
