"If I could get [showrunners David Benioff and Dan Weiss] to do more I would take 10 more seasons. But we take their lead on what they think they can do the best show in,” Bloys said.
Also per Us Weekly, the show's creators have not yet determined how many episodes will be in the final season. Season seven of the show, which is scheduled for release next summer, will have seven episodes—though they usually air 10 episodes per season.
A blooper trailer from Game of Thrones's sixth season was released last week at Comic-Con.
Because of the late start date for the seventh season, Bloys also said the show will not be eligible for next year's Emmy Awards. Game of Thrones is nominated for 23 Emmys this season.
