Like the previous season, it will largely consist of original content currently not found in George R. R. Martin’s A Song of Ice and Fire series, but also adapts material from the upcoming sixth and seventh novels The Winds of Winter and A Dream of Spring.[citation needed] The series is adapted for television by David Benioff and D. B. Weiss.
HBO ordered the seventh season on April 21, 2016, three days before the premiere of the show’s sixth season, and began filming on August 31, 2016. The season was filmed primarily in Northern Ireland, Spain, and Iceland.
