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!
I definitely think that theatre is something I'll keep coming back to in my career for as long as I can. I also think theatre's something you have to be very fit to do. I am fairly fit, but I don't think I could do it all the time.
When you're seventeen to early twenties, that's the time you're trying to work out who you are. If you're trying to make some kind of artistic or creative impact, that's the age when you start to figure out how to do that.
I sort of try to read the books when they come out impartially and not make up my mind, but the fact is when I was reading the sixth, 'Harry Potter And The Half-Blood Prince', there were bits in there where I was going, 'God, I would love to do that because it's so good'.
People tell me I look mournful. They say, 'Cheer up, Dan, it's not that bad!' Sometimes I just look into space, which freaks people out. If I was ever required to do anything other than look haunted, I could. I'm a happy person.
I don't know where my romanticism comes from. My mom and dad would read to me a lot. 'Treasure Island,' 'Robinson Crusoe,' tales of chivalry and knights, things like that. Those are the stories I loved growing up.
My parents are left-wing, and I would describe myself as that. But also, you know what? I wouldn't describe myself as that. Because I don't have to. Because I'm not a political party. Most people are a little bit of each, and we change our mind on various issues.
I always saw Michael Gambon wearing madly psychedelic socks, and I always thought that's it is one of the few areas where men can really express colour and have a bit of a dandyish quality to their outfit.
I've always thought that as long as directors and casting directors don't see me as just Harry Potter, I'll be OK. People have shown a lot of faith in me, and I owe them a huge debt. They're letting me prove that I'm serious about this.
The best thing I've learned is, if you're going out, never go out alone - you leave yourself vulnerable. If you've got someone else there you trust, they can say, be wary of that person. I probably used to be too trusting of people.
