Game of Thrones's George RR Martin: 'I'm a feminist' So how does he get inside the head of, say, his teenage characters? 'Yes, you're right I've never been an eight year old girl,' he says, 'but I've also never been an exiled princess, or a dwarf or bastard. What I have been is human. I just write human characters.

'But importantly they hate them as people, because of things that they've done, not because the character is underdeveloped.' The pitfalls of lots of other fantasy texts, he says is when writers stray into writing in sterotypes. But because Martin has a sprawling world with thousands of characters (and five books to do it in), he has the luxury of developing each one fully. 'Male or female, I believe in painting in shades of grey,' he says. 'All of the characters should be flawed; they should all have good and bad, because that's what I see. Yes, it's fantasy, but the characters still need to be real. Martin should be used to female adoration by now. Although he has only hit mainstream consciousness in the last few years (his books have sold more than 20m worldwide), he has been a minor celebrity on the science fiction circuit for years. His wife's first words to him, when she met him at a science fiction conference in 1975 were that his first novel, A Song for Lya, "made her cry." Now he is mobbed wherever he goes - his trademark fisherman's cap an instant giveaway that he is the man behind the globally successful franchise.

Often crucial conversations between characters happen while one of them is having sex (not always mentioned in the book) - something that has the American academic Myles McNutt to term them "sexposition." Is it simply because we couldn't be trusted to pay attention otherwise? McNutt asked on his blog. It's as though they think having a prostitute appear and only talking, without actually having sex, would be some sort of cop-out. In my view, at least, it's the other way around: it just feels lazy. Daenerys Targaryen, the would-be queen, played by actress, Emilia Clarke PHOTO: HBO Gina Bellafonte in The New York Times went further. Last year she wrote: "all of this illicitness has been tossed in as a little something for the ladies, out of a justifiable fear, perhaps, that no woman alive would watch otherwise." The truth was, she sniffed, "Game of Thrones is boy fiction patronizingly turned out to reach the population's other half." Female GOT fans lept to Martin's defence, including Emily Nussbaum from the New Yorker who wrote that the strength of the series was "its insight into what it means to be excluded from power: to be a woman, or a bastard, or a "half man."" But Bellafonte's comments still rankle with Martin a year later because he is, at heart, a feminist, despite being cautious about admitting it. "There was a period in my life when I would have called myself a feminist, back in the seventies, when the feminist movement was really getting going and growing out of the counter culture of the sixties," he says. But the feminist movement has changed. Sometime in the 80s and 90s I read some pieces by women saying that no man can ever be a feminist and you shouldn't call yourself that because it's hypocritical, so I backed off. I thought if the current crop of feminists believes that no man can be a feminist, then I guess I'm not one.

He chuckles behind his candyfloss beard. "To me being a feminist is about treating men and women the same," he said. I regard men and women as all human - yes there are differences, but many of those differences are created by the culture that we live in, whether it's the medieval culture of Westeros, or 21st century western culture.
