However, if GRRM still wants to have a say on the show, the book should definitely release by the end of this year. The television phenomenon comes with a grueling schedule and the cast and crew have to film simultaneously in different countries. When filming, the chronological order of the scenes isn’t followed at all.
In that way, Game of Thrones is quite different from what’s written in the books since 10 episodes are already finished before the team even starts shooting.
During an interview with Producer Bryan Cogman, he said. “We continue to tinker with all of the scripts through prep and production. But they’re generally camera-ready when we finish them. They have to be, as we have to have all 10 scripts complete well before shooting starts.
We shoot all 10 episodes simultaneously, out of order, like a big, 10-hour movie, with two shooting units going at all times, sometimes in different countries.”
Meanwhile, last year Vanity Fair was told by Benioff, “If you know the ending, then you can lay the groundwork for it. And so we want to know how everything ends. We want to be able to set things up. So we just sat down with him and literally went through every character.”
