Stage is much more intimidating than going before the cameras, because you can really screw up, and can't do a retake.

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.

Acting is really instinctual and I think you can overanalyse what you're doing. A lot of it has to be based on instinct.

I don't want to say I'll never play someone with a cockney accent, but I think I would be irritated by me doing it.

I suppose whenever you go through periods of transition, or in a way, it's a very definite closing of a certain chapter of your life. I suppose those times are always going to be both very upsetting and also very exciting by the very nature because things are changing and you don't know what's going to happen.

I'm also a fan of ridiculously coloured and patterned socks.

I'm always amazed at the way some actors' behaviour is truly disgusting. That's one thing that will never happen on one of my sets if I ever direct.
