Fame is damaging when people become reliant on it for their sense of self, and their identity, when fame is linked to how you see yourself.

I've not got a girlfriend at the moment. Somebody said, 'Do you worry girls are just giving you attention because of who you are?' I was like, 'I'm 17, it's wonderful.'

I'm quite confident, but I don't fancy myself. I don't really care about how I look.

When you're in the position I'm in, you have two options: you can either shut yourself off from everybody, from the world, and not live a full life. Or you welcome everybody into your life and occasionally somebody will try to take advantage.

I was very sad to leave Harry Potter but equally there will be an element of excitement about the idea that a script might come in and I don't have to go: "I'm sorry, I'm kind of busy for the next four years." The idea of that is quite exciting.

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.

Some people think I am gay, which I think is awesome.
