Being in Harry Potter is like being in the Mafia. Once you are in, you are never really out.

I was in the bath at the time, and my dad came running in and said, 'Guess who they want to play Harry Potter!?' and I started to cry. It was probably the best moment of my life.

I'm not a religious person. My mom was of Jewish blood and my dad was Protestant.

I like the idea of not having to do stuff for the money, and if I want to, I can pick indie projects for the rest of my life and be quite happy doing that.

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.

My parents were what I like to call proper musical fans. Lots of Sondheim was played in the car.

The one piece of advice I would give to any actor is, if you want to go out on the street without being recognised, without even being looked at, go out with a 6ft 8in beautiful transsexual. No one gives you a second glance. Especially when you're 5ft 5in.
