The crew of the HBO hit fantasy show “Game of Thrones” just celebrated 90 days of production, and on Sunday, creator George R.R. Martin caught up with Adria’s News to discuss where the series is headed.

Martin is currently at work writing the sixth book to the “Game of Thrones” series and is also scheduled to write one of the episodes in season three of the HBO series. In his interview, he unveiled several unexpected details, ranging from planned shooting locations for the previous two seasons that got scrapped to which aspects of the story line he will be involved in adapting for the small screen.

Martin, a self-professed fan of “everything on HBO,” described the genesis of writing “Game of Thrones” as a reaction to his career as a Hollywood screenwriter. One of his biggest frustrations of being a screenwriter was having to continually reduce the scale of scenes to fit the demands of a budget.

“For this reason,” said Martin, one of his first decisions about the series was that he would “write as many scenes in castles as possible, I will create as many characters as possible, I will write about gigantic battles. ...

“I really didn’t expect my novels to be adapted for television,” added Martin.

Of course now that they have been, Martin has had to cope with the reality of altering his content for the serialized television format. For this reason “A Storm of Swords,” the third book in the series, has been split into two seasons.

“More or less the third season will talk about the first half of the third book and the fourth season will be about the other half and perhaps will also appear the first chapters of ‘Feast for Crows and ‘Dance with Dragons,’ because its action will be told chronologically,” said Martin. “The limits between every season and every book are not clear and, in fact, in the second season we saw some things of the third book.”

Martin also hinted that splitting up the book would buy additional time for him to work on the sixth installment, which will be titled “The Winds of Winter.” “I have to write the books, that’s the most important thing for me, and I don’t want them to catch me up,” he said of the HBO series.

Still, Martin added that he was trying not to rush himself, adding, “when I finish this saga I will be judged for the quality of the books, not for the speed of my writing.’

When asked about one of the most shocking turning points in the book, the infamous wedding that takes place at the Twins in book three, Martin said he would not likely be responsible for adapting that chapter for the HBO series, if it is included at all. “If this chapter is finally included in the third season it would appear later, after mine, and I think [the show's creators] David [Benioff] and Dan [Weiss] want to write that by themselves,” said the author.

Speaking of future shooting locations, Martin also divulged that the producers had previously planned to film the King’s Landing in Spain, but eventually changed their mind to Croatia. “I probably shouldn’t tell you this, but we were about to film in Spain. You have a lot of castles and interesting locations, especially in the south of Spain,” said Martin. “But who knows? Perhaps we’ll use Spain in the future.”

As for the forthcoming third season, Martin said the crew would return to Iceland to shoot the land beyond the Wall, and adding a new location in Morocco. “The news is that this year we will be filming in Morocco, I suspect for Daenerys stuff,” he said.
