"Somebody I love and have a huge amount of respect for once told me something that, to this day, I don't really think I understand. It was probably toward the end of Harry Potter, and they were talking to me about afterwards and that kind of stuff. And they were saying, "You need to think of yourself as a brand and you need to protect that brand." I just don't understand what that really means in terms of being an actor, and I also think I would find that a slightly soul-destroying way to look at myself."
