I think I'm always very naïve. With 'Kill Your Darlings' and 'Horns', I'm like, "Why wouldn't everybody love this?" But I guess it's going to divide people in some ways. But if you're willing to go with it and suspend your disbelief, you're going to get something amazing and something unlike anything else.

I was very much a product of the public-school system. There was only one other kid in my class who had parents not involved in the stock market or law.

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.

It's interesting because people assume that because I'm famous I know all famous people.

I've done seven movies in eight years, and with each movie I feel like I'm learning a lot. I'm still young-ish, so I still feel like I'm in the zone of learning and creating. Those are the perfect places to do that. And in a weird way, you have a lot of freedom.

I don't think that you necessarily need a certain type of background to take on roles. You see actors from very, very privileged backgrounds playing working class characters and vice-versa. I don't think your background limits you as to what you can do.

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