We'd love to hear about your audition.
My drama teacher called my name out in an assembly, so I walked up to him and he asked me, "I want to know if you'd like to audition for a part in the Harry Potter movie?" I did my first audition for a laugh. But as I got up the ranks, they got more serious. It wasn't until I did the last one that I realized I had a chance of getting it. And then I got the part, which was wonderful.

When you were auditioning, did you know how to pronounce Hermione's name?
[Laughs] Yes!

Did you always want to be an actor?
Yeah, for ages. Probably since I was five or six.

What kind of acting have you done?
I've been in loads of school plays. I did The Swallow and the Prince, where I played the Swallow. I also did Alice in Wonderland, where I played the Angry Cook. My favourite was the musical Morgan Le Fay because there were lots of good songs in it. I love to sing.

So let's talk about the movie. How do you feel about seeing yourself on the big screen?
I really am self-critical. I'll say, "Look! I look so stupid. I look so awful!"

What's your favourite scene?
The Troll scene is the best; they had loads of stunts to do.

Was there anything you wanted to take home from the set?
Loads of stuff! I'd love to take home one of the chess peices. They're amazing. They're massive and I love the colours of them. They're spooky as well. Most of the pawns have weird eyes. It's scary!

What magical powers do you wish you could have?
I'd like to fly.

Did you get to do any flying in the movie?
No, it was unfair! Hermione didn't get a broomstick.

If you could cast a spell, what would it be?
I think I'd like to help people in need.

Do you think you have a lot in common with Hermione?
We're the same 'cause she loves cats and so do I. Otherwise, we're opposites. I love school and I try hard, but I'm not as clever as Hermione.

What are your favourite school subjects?
Well, nonacademically, I love sports. I play rounders-- which is a lot like baseball-- hockey, tennis, athletics, everything!

Are there any subjects you hate?
I hate geography and math. I hate them, hate them, hate them!

How would you like to see the Harry Potter series end?
I would like Voldemort to be properly killed-- dead-- so Harry won't have any more problems. For Ron's dad to get really, really, superduper rich. For Malfoy's parents to go broke. And I'd like Hermione to get a really good job.

Do you think Hermione will marry Ron in the end?
No way! Ewww! I think it's weird because I'm thinking of myself in the part.

How would you describe yourself in three words?
Sporty, determined, and try-my-best-at-everything.

What was the funniest thing that happened on the set?

We did a lot of pranks! Once Daniel Radcliffe, who plays Harry, brought in a remote-controlled whoopie cushion. He tried it on me, but it didn't quite work! Then he tried it on someone else who was going to sit down on a massive sofa. When it went off, Chris Columbus, the director, said, "Cut! What is that thing?" And everyone burst into laughter. Dan pulled other pranks, too -- like making little labels that said "Kick me" or "Punch me." He would stick them onto the backs of everyone who came into sight. It was really good.

Did your friends ever bug you to tell them stuff about the movie?

Never! Some people did, but they weren't my friends.

Do you have a favorite character?

One of my favorites is Hagrid. Robbie Coltrane, who plays him, does a really strong accent. I think it sound so funny!

Did you get to meet J.K. Rowling?

I did! I met her just after I got the part. I liked her -- she's fun!

If you could take one magical thing from the movie and make it real, what would you pick?

That's obvious -- my wand! Then if I ever needed something, I could always get it.

There's a scene in the movie where you make a feather float. Can you tell us how you did that?
