How fast can George R. R. Martin write?: Martin is used to being asked at this point how long it will take him to finish his 7-book series. Book five was released in 2011, six years after book four, and the show is already halfway through book three. Given the pace he's set in the past, Martin was asked if he's worried the show will catch up to him. "They're moving faster than I am," he said. "I have not failed to notice this. I still have a considerable lead. At least that's what I'm telling myself." Martin said he hopes book six, The Winds of Winter, will be done in time for the show to adapt it while he finishes book seven (which Martin has said will be called A Dream of Spring), but the show's future might not be certain either. With HBO executives in the audience, Benioff noted that, despite rumors to the contrary, season four has not yet received the greenlight.
