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.
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 see myself doing Harry Potter films as long as I'm enjoying it and as long as they are going to challenge me as an actor. I want to be an actor - it's my aspiration - so I want to do other films. I want to write something and I want to direct something!
Every job I do, I like to think it makes me better or I learn things. It's all about how much something's going to stretch me or test me.
