My idea of relaxation is not lying down by a beach. I have to move around, do stuff. Though I'm a massive quiz show person.

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

I think one of my favorite things to do is just lock myself up in a small room and listen to music and watch films for a day. Also I just like seeing my friends. We have pizza parties which means I get four friends round, we eat a pizza and we're really lazy and we play PlayStation.

What I learned is that acting is to a large extent about trying to stave off self-doubt long enough to be natural and real onstage.

You never want to be forced to do something. But the world around you starts to influence you in ways you never expected.

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 an easy person to love. There are lots of times when I'm a very good boyfriend, but there are times when I'm useless. I mean, I'm a mess around the house. I talk nonstop. I become obsessed with things.
