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.

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

You couple that with how I looked when I was younger, and growing up... The voice is not quite breaking. It's awful. No, I don't enjoy that at all. But that's one of the things people love and find so endearing about the Harry Potter series, and why they've lasted so long. Because people have grown up with us, and they care about the characters. They're not just some characters in the film, they're people you can relate to, and you care about, and you grew up with, and when they die in this film, people feel it!

Approaching a comedy character is fun because you get to sit down with the director and ask, "What makes you laugh?" Then you end up bouncing ideas off each other.

I did enjoy theater. I actually do prefer making films and television, but it was a learning experience for me, because I got into television at 5 and film at 11, and theater was something I completely bypassed.

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.
