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'm not a big fan of people knowing too much about me.

I get too excited about football and rugby.

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 think David Yates was just like, "You've got on with it for a few years, I'm gonna let you off the hook." And also, I think it's because the action side of stuff that we were doing, it was going to be very difficult to do all that with all the prosthetics on. It was gonna be hard work, and I think they just said, "You know what?" I think they put a level of trust in me, as well. They said, "You know, we're gonna let Neville Longbottom lose the fat suit, lose the teeth, lose the Adolf Hitler hair."

You know, girls in general are scarier than Voldemort.

Rupert Grint is exactly like his character Ron, in that they are both incredibly funny, friendly, and loyal.
