Suffice to say, no one would be shocked that HBO is currently thinking about greenlighting another season of Game of Thrones. In fact, it's rather more of a question of when will they make the announcement, not if. But reports are coming in that HBO is currently thinking over whether to film Seasons 3 and 4 simultaneously, guaranteeing Game of Thrones medieval goodness for years to come. The current rumor is that HBO has quietly told the film crew in Northern Ireland to plan on nine months of filming next year.
The showrunners have also previously stated that Martin's third book, A Storm of Swords, is so massive that it would need to be adapted over multiple seasons, so Seasons 3 and 4 would presumably cover that particular book. Of course, this is all just rumor right now, and HBO likely won't make any announcements until after season two premieres. I'd say this is a strong possibility though.
And if HBO needs two seasons for A Storm of Swords, how many will they need to cover everything in A Dance of Dragons? Three? Four?
Game of Thrones is an American medieval fantasy television series created for HBO by David Benioff and D. B. Weiss. Based on author George R. R. Martin's best-selling A Song of Ice and Fire series of fantasy novels, the first of which is called A Game of Thrones, the television series debuted in the U.S. on April 17, 2011. The production is based in Belfast, Northern Ireland, with additional locations elsewhere in Europe also being used. The show's cast is mainly British and Irish.
Highly-anticipated since its early stages of development, Game of Thrones was very well received by fans and critics. The series was picked up for a second season on April 19, 2011, two days after its premiere. On July 14, 2011 the nominations for the 63rd Primetime Emmy Awards were announced, with Game of Thrones being nominated for 13 categories, including Outstanding Drama Series, Outstanding Casting for a Drama Series and Outstanding Supporting Actor in a Drama Series for Peter Dinklage, which he won. The series also won an Emmy for Outstanding Main Title Design the weekend before, at the Academy's non-televised technical Emmy awards presentation.
