I always love costume, and I'm always heavily involved in how things should look. Or how they should feel really, because that's part of the way I suppose I get into character in some ways. It's a lot about costume.

I went to school, and I remember that you had to do these tests to find out what set you're in - how clever you are. I put down "Kit Harington," and they looked at me like I was completely stupid, and they said, "No, you're Christopher Harington, I'm afraid." It was only then I learnt my actual name. That was kind of a bizarre existential crisis for an 11-year-old to have, but in the end I always stuck with Kit, because I felt that's who I was. I'm not really a "Chris."

It's very difficult to say anything in Icelandic. I can say "takk," which means "thank you." That's about all I learned.

Working with animals is always going to be tough because the animal doesn't know it's an actor.

When you're a lead role, I'm learning that you set a tone for the movie in a way, like a director does, or like other actors do. But it seems like you set a mood on set.

It's a nightmare if you're working with someone you don't get on with, especially if you have to be in love with them.

Iceland, I'm in love with that country, the people are incredible.
