According to this interview with Jason Momoa, Momoa expects that he’ll be returning to Morocco as well as Northern Ireland to shoot the Game of Thrones series in late June. Despite the way it’s written—as if it’s a foregone conclusion—we suspect that in fact Momoa was speaking speculatively. The actors have been informed of the prospective schedule if the show goes forward, so that they can plan their professional engagements accordingly with that possibility in mind.
