Game of thrones A Storm of Swords

The third season will be based on the first half of the novel A Storm of Swords. Benioff had previously said that A Storm of Swords would need to be adapted in two seasons on account of its length.But Benioff and Weiss also noted that they thought of Game of Thrones as an adaptation of the novel series as a whole, rather than of individual books, which gave them the liberty to move scenes back and forth across books according to the requirements of the screen adaptation.According to Benioff, the third season will contain a particularly memorable scene from A Storm of Swords, the prospect of filming which was part of their motivation to adapt the novels for television in the first place.George R. R. Martin will write the seventh episode, tentatively titled "Autumn Storms", and Bryan Cogman will write the fifth.Other returning writers are Benioff and Weiss, and Vanessa Taylor.
