Although the sixth season of the fantasy show has yet to premiere, and the next book of the origin series has yet to come out and won't be out for a while, Deadline reports that HBO is in talks to renew Game of Thrones for Season 7 and Season 8, which is amazing news for fans and for the cast.
The series was renewed for a seventh season, which is scheduled to premiere on July 16, 2017, and will conclude with its eighth season in 2018. Set on the fictional continents of Westeros and Essos, Game of Thrones has several plot lines and a large ensemble cast. The first story arc follows a dynastic conflict among competing claimants for succession to the Iron Throne of the Seven Kingdoms, with other noble families fighting for independence from the throne.
