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.

Obviously, when you're in theater, you have to be in character. You have to prepare for the unexpected. You have to be able to react to things that don't necessarily happen every night, or aren't supposed to happen every night. And you have to react to it in character. In six months, 192 shows, those things did happen. And the experience of that, the ability to stay in character, I feel like I've learned a great deal.

I was being a sort of rebellious teenager, really. But there was never any point at which I was considering leaving Harry Potter. If I were to stop acting, it would have been after. As long as they kept asking me to come back, I was gonna keep doing it. 'Cause I loved the story! There's no way I would have left.

I'm very comfortable being at home and keeping my head down, really. It's nice being invited to night clubs and stuff, which is nice once in a while, but I prefer to kind of keep to myself.

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.

There's not many people on the face of the earth that don't know Harry Potter is Daniel Radcliffe. He's had that since he was eleven years old, yet he hasn't changed since the day I met him.

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.
