I never really looked at it like that, but it's true. It's weird that it's been half my life. Because I lead these two separate lives. I've got my life and Harry Potter, where I travel the world, I make films, I meet amazing people, I do press junkets and stuff. And then I go back home to Leeds, where I live, and I've got the same friends from before. I still go to the pub. I still go to watch the football, soccer. And I go shopping at my local shop.

What I've found is that stage is very much a foundation of acting. It's where it all began and you're working with that repetition.

You hear about all the great British thespians doing stuff on the West End and that kind of thing, and I missed out on that. Alan Rickman actually suggested to me that I should try it. And I thought, "Geez, I really don't want to do that." But he must have recommended it for a reason, so when an opportunity came up, I took it. And it was tough. It was hard! But by the end of it, I absolutely loved it.

I think screenwriter Steve Kloves does such a difficult job. And he does a bloody brilliant job, too. Transferring these Harry Potter books into films and making them coherent is one thing. But making them entertaining, as well, is quite another... He does a tremendous job, and he gets a lot of stick. And it's really unfair sometimes, and I challenge anyone else to do the job he does.

I was a short, chubby kid, pretty shy.

I'm very much open to the possibilities.

Michael Gambon telling filthy jokes and Alan Rickman talking about scrambled eggs, just really normal things, and yet they're these amazingly, superb, famous actors. I feel so privileged to have been around them on the set of Harry Potter.
