With the fourth series soon to air on UK screens, author George R.R. Martin has been discussing the possibility of a Game Of Thrones movie possibly bringing the story to a close, some way down the track.



“It all depends on how long the main series runs,” says Martin. “Do we run for seven years? Do we run for eight? Do we run for 10? The books get bigger and bigger. It might need a feature to tie things up, something with a feature budget, like $100 million for two hours. Those dragons get real big.”



Martin has also discussed the possibility of the TV show catching up with the books, but remains hopeful that he can get the last two books out in good time.



“I’m hopeful that I cannot let them catch up with me. The season that’s about to debut covers the second half of the third book. The third book was so long that it had to be split into two. But there are two more books beyond that, A Feast For Crows and A Dance With Dragons ."



“ A Dance With Dragons is itself a book that’s as big as A Storm Of Swords . So there’s potentially three more seasons there, between Feast and Dance , if they split into two the way they did [ with Storms ]. Now, Feast and Dance take place simultaneously, so you can’t do Feast and then Dance the way I did."



“You can combine them and do it chronologically. And it’s my hope that they’ll do it that way and then, long before they catch up with me, I’ll have published The Winds Of Winter , which’ll give me another couple years. It might be tight on the last book, A Dream Of Spring , as they juggernaut forward.”



Best get writing then, George. Game Of Thrones Season 4 airs on Sky Atlantic on 7 April 2014.
