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.

I've always been a bit of a self-doubter, I think a lot of actors are. I still am.

I wear quite fitted clothing. I don't like wearing baggy stuff.

I've got like a weird bond with horses. I'm kind of a horse whisperer, I don't know what it is. I'm not great on a horse. I'm getting better, but I'm not brilliant. So yeah, I've spent a lot of time with horses. They're great creatures, I love them. I do love riding them when I get the chance to.

Each project changes you a bit.

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."

I've inherited the bad poetry genes, but not the inventor genes.
