I'll miss some of the opportunities that playing Harry [Potter] brought me.

I was worried on a personal level because I wanted to be slightly taller than I am, ideally. But I've now accepted it. Basically, I came to the conclusion a while ago that you can either be really bitter about it or you can make loads of funny jokes.

I've not got a girlfriend at the moment. Somebody said, 'Do you worry girls are just giving you attention because of who you are?' I was like, 'I'm 17, it's wonderful.'

Harry Potter star Daniel Radcliffe has confessed that until recently, he thought the 16-year-old fellow tween idol [Justin Bieber] was a female. 'I only heard Justin Bieber for the first time two weeks ago. I genuinely thought it was a woman singing. I'd never heard it before. Is it big in England yet?'

It's mainly about working hard and proving to people you're serious about it, and stretching yourself and learning. The mistake a lot of actors make, particularly young ones, is allowing themselves to feel that they're the finished articles, the bee's knees, and it's not true.

I'm never going to be in something as commercially successful as 'Harry Potter' ever again. It's impossible. So that gives me incredible freedom to go off and make the slightly off-the-wall films that I want to make.

I'm possibly a very morbid person but I think about death a lot. I don't know if it's maybe from being on films that's often playing Harry [Potter] or I just think it's a natural thing that I have. It's something that I think about just because it's fascinating in a very alien kind of way.
