In latest 'Game of Thrones' Season 5 news, book writer George R.R. Martin revealed whether or not he will write a script for the popular HBO series in addition to writing the upcoming 'Winds of Winter' book.

"Not this year, no - once again because I have this book [Winds of Winter] to finish," said Martin on the Vulture website.

The 65-year-old New Jersey native also talked what his loyal followers can expect when the latest installment of the popular 'A Song of Ice and Fire' series finally arrives in book stores.

"I'm going to open with the two big battles that I was building up to, the battle in the ice and the battle at Meereen-the battle of Slaver's Bay. And then take it from there," said Martin, according to a Hallels report.

Martin also discussed if he would be appearing on the set of the upcoming season of Game of Thrones.

"I don't know. I might make it over there early next year, but I've got to finish the book The Winds of Winter. So I'm making the trips I'm already obligated to make, but I'm not adding any new trips at this time. So I don't think I'm going to do a set visit this year, sadly," said Martin to Vulture.

He also gave his thoughts regarding the recent announcement about the new actors joining the cast when the fantasy show returns next year.

"You know, it varies season to season. This season, most of those cast members are new to me as well because I haven't been involved in the process. I've been doing a lot of other stuff. In the earlier seasons I was much more involved with casting," said Martin.

"At this point, we're five seasons in, we have the best casting director in the business in Nina Gold, David [Benioff] and Dan [Weiss] have been running the show, and it's a well-oiled machine, so it really doesn't need me down there with the oil can squeaking at the wheels," he added.

As of right now, there is no specific release date regarding the forthcoming book 'Winds of Winter', since Martin is still in the process of writing it.
