A good illustration of Harington’s sweet nature is when he talks about castmate Gwendoline Christie, who he’s good friends with. Christie plays the statuesque warrior Brienne of Tarth, and as soon as I mention her he grabs his phone, Googling furiously. What emerges is a photo of him and Christie at a film premiere, her towering beautifully over him in a gold mini dress. “Look! I look like a fucking Hobbit stood next to her!”, he shouts, chuckling wildly.
