According to Dance (and other rumors online) filming of Season 3 will start in May or June soon after Season 2 airs. This adds a little credibility to the earlier rumor that HBO will film Seasons 3 and 4 in one go. The earlier start date gives them plenty of time to not be rushed before the Season 3 premiere date.
Dance, who plays Tywin Lannister, said:
"We just finished the second series of Game of Thrones - we start [again in] May / June of next year," revealing: "I haven't read what we're going to be shooting."
