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.
