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.

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

I love going out. I love partying.

Attention gets you the opposite sex sometimes.

You have to look at your blessings, don't you? With Thrones, I have to realize that, whatever happens, and for all the stress and the pressure that goes with it, it's been an extraordinary journey and I know I'll look back later in my life and think, 'That was crazy, that was amazing.' It's something that very, very few people experience, and I love that.

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.

You know obviously a big TV or film break would be lovely, but I find that I’m essentially a theatre trained actor and that’s what I love doing. I love fringe theatres in London, I love theatres like the Royal Court, Soho and the National obviously and if I could work in any of those and be a jobbing actor for a while then I’m very lucky.
