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.

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.

I never contemplated. I just went in there and did my acting. I never thought, "What's the character actually feeling here? What's he trying to get across?" And never looked at it from that classically trained actor's point of view.

Theater was such a different school of acting. But it really is a foundation of everything. It's where it all started! And I feel like I learned so much.

I get recognized now and again, but the paparazzi aren't following me around.

I love making people laugh, and to be able to be that humorous character was great. And I actually was very similar to Neville Longbottom. I was very shy and chubby-cheeked. I wasn't bullied at school, but I wasn't particularly outgoing. We were similar. And so I loved playing him.

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.
