If I can make a career for myself after Harry Potter, and it goes well, and is varied and with longevity, then that puts to bed the 'child actors argument'.

Everyone on the set has a mobile phone, and I found by pushing a few buttons, they could be programmed into different languages. I fixed Robbie's Coltrane to speak in Turkish.

I Google myself to see what come up when you Google Daniel Radcliffe because that's always amusing.

People do incredible things for love, particularly for unrequited love.

I definitely want to go on acting for as long as I can find employment. I'm never happier than when I'm on a film set. I just want to keep working.

I think, as an actor, and particularly if you are playing the lead in something, you have to view yourself as the head of department for the cast. All of the other departments are accountable and have somebody at the helm who is leading them all the time, and I don't think that the actors should be any different.

I am very critical! I hate watching myself but I know I have to because I'm going to be asked so I need to have some sort of semblance of what the films with me are like. But it's not an enjoyable experience watching yourself. I hate it less than I used to but I still don't enjoy it.
