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'.

Maybe it's a compliment to the film that you can't do that with it, that it can't be explained in 15 seconds.

I think honesty is the most heroic quality one can aspire to.

Some people think I am gay, which I think is awesome.

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'm an atheist, but I'm very relaxed about it. I don't preach my atheism, but I have a huge amount of respect for people like Richard Dawkins who do.

Working hard is important. But there is something that matters even more, believing in yourself.
