Also, fans of the books that may have been wondering how the climactic "Battle Of Blackwater" would be depicted onscreen need not worry. According to one of the show's producer David Benioff, fans won't be "shortchanged"..
“This is season is about a country at war,” says Benioff, who along with Weiss, successfully lobbied HBO for a 15 percent budget increase to stage the second season. “And we felt like if we didn’t see the most important battle of this entire war onscreen, we’re going to shortchange viewers.”
