Alan Rickman told me to do a play, so I did. Because when Alan Rickman tells you do something, you go and do it.

As long as I'm acting and doing what I love, I'll be happy.

There was never any point at which I was considering leaving Harry Potter. If I were to stop acting, it would have been after.

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!

Alan Rickman, who was mentored me a lot. He was very keen to offer his opinions on stuff. Not in a pretentious way. Not in a patronizing way.

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.

In fact, my favorite Beatles song is "In My Life." And from that, you can gauge that my friends mean so much to me. I love John Lennon, so it's kind of like moody... There's a lot you can gauge from that. As insignificant as it seems, as an actor, it's an interesting way to approach a character.
