On season three:
Weiss: Season two is a 100-hour-a-week job. It doesn’t leave a lot of time to think about seasons three and beyond. But yes, Storm of Swords … very long, dense book.
Benioff: A Storm of Swords will not be a single season. Beyond that, we’d rather not speculate, as HBO has not yet confirmed a third season and we’re not in the mood to jinx anything.
