Because [writers] Dan Weiss and David Benioff have done such a great job in adapting them, that's what we work with. It serves no purpose to anybody for actors to come onto a set with a well-thumbed copy of the source material and start querying why this or that line has been left out of the script. It's probably been left out for a good reason.

If I talk about Charles Dance I am talking about something else, something I operate and wind up and have to make an impression with and use to transmit someone else's screenplay.

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.

I have to admit that I haven't read any of the books [of George Martin's "Game of Thrones"] and I don't refer to them. Apart from anything else they're very thick [in size] and they frighten me. A terrifying prospect.

I'm playing one of the principal roles, which gives you more clout and more confidence.

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.

You have to attempt to be objective about yourself.
