At that age, filming Harry Potter, 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. And so when Jason Isaacs started throwing up these ideas, I thought, "Whoa. What an interesting way to look at acting." Which is why, again, I would do theater.

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.

At least I like to keep it the same. That's why I've got all the same friends. That's why I go back to Leeds as much as possible. I don't know if you know much about England, but Yorkshire is a very sobering place. In the North. It's very gritty. Old mining villages. And people don't really care about celebrities up there. And it's great. And that's why I get back there whenever I can. 'Cause it keeps me very grounded, and it keeps my life very normal, whatever that is.

Don't get paparazzi following me everywhere. My life there is exactly the same as it would have been if I had not been in Harry Potter. So for me, Harry Potter isn't something that changed my life. It's just something I did that was a lot of fun, and I got to experience amazing things from. But my actual, personal life is the same.

I mean, I must confess I don't own Harry Potter DVDs. My parents do. They have them all. And they like watching them.

I'm very self-conscious as an actor, with performances and things, and I don't like watching my own stuff.

My parents are proud of me being an actor.
