Your senses are reeling all the time. Finally you find something to write and the very next day you go out and see something else which totally contradicts what you've written and every conclusion you've come to.

A car to pick me up every day, a chair with my name on it, everybody being very polite... what can you do except sit back and watch it all, try to take it all in?

There is a huge fan base, they're very knowledgeable and very loyal. I was astonished - before I started working on the series I didn't know anything about Game of Thrones. I hadn't heard of the books. When it started going out, people were coming up to me in the street saying [fake cockney accent] "oh, Game of Thrones, f------ wonderful.

Power is always a corrupting influence. In this mythical time - let's call it medieval, feudal - people in power are dictatorial and don't want their positions of power to be threatened.

People like Tywin Lannister are very much victims of that system, and of that environment: 'This is my place, don't threaten it'. I don't know how relevant that is to today. Politics is the most corrupt profession on earth, no matter where you are.

It starts with the writing - which is really, really good. And the production values are phenomenal. HBO and Sky have spent money on it, and you get what you pay for. This has money put into it properly - not lavish amounts - but as each season is successful, they maintain the money that's being spent to maintain the quality.

It's a question of keeping one's eyes and ears open and watching how other people play the game. They're watching me too, to see what my attitude is like.
