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.

I think that the process of making a film is an underrated factor in how that film turns out.

I know I'm not a coal miner, but I do long hours and I never complain, and there is nowhere else I'd rather be. So, yeah, that's how I'd define myself. I want to do it right, and prove people wrong once and for all about the myth of child stars.

And I'm slightly in love with Scarlett Johansson: she's just stunning. And she's bright, which is incredibly sexy.

Normally I sit there in the films really hating watching myself. Loving watching the films, hating watching myself.

Go boldly and honestly through the world. Learn to love the fact that there is nobody else quite like you.

If you spent a proper amount of time with me, you would probably wonder if I was on drugs - I'm not. I'm just incredibly hyperactive and manic. I can be quiet and serious at the same time.
