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

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.

My preparation is mainly just knowing the lines and getting in and knowing where your character is, knowing what it's about and having ideas that you can put in on the day.

People tell me I look mournful. They say, "Cheer up, Dan, it's not that bad!" Sometimes, I just look into space, which freaks people out. If I was ever required to do anything other than look haunted, I could. I'm a happy person.

I'm very proud of being Jewish. It means I have a good work ethic, and you get Jewish humour and you're allowed to tell Jewish jokes.

How irritating it must be for people, to be bombarded with me!

I will never, ever do a film as successful as the Harry Potter series. But neither will anyone else.
