As much as I would love to be a person that goes to parties and has a couple of drinks and has a nice time - that doesn't work for me. I do that very unsuccessfully. I'd just rather sit at home and read, or go out to dinner with someone, or talk to someone I love, or talk to somebody that makes me laugh.

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.

For me, you go to university to meet lots of different people from different backgrounds. I think that's one of the most important things you get there. And you also get some sense of direction regarding what you want to do when you leave. I sort of know what I want to do in my life - I want to act and ultimately I'd like to write. And in terms of meeting people from different backgrounds, that's what you get on a film set. So the two most valuable things that university would have given me I've sort of achieved by being on a film set.

Because of the life I've had, I'd grown up quicker than most people.

I get constantly mistaken for Elijah Wood.

I get constantly mistaken for Elijah Wood. I was in Japan and someone held out a photo of him for me to sign.

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.
