Longtime Game of Thrones writer Bryan Cogman confirms his potential spinoff is dead

Variety

Co-executive producer Cogman is the only Game of Thrones writer to be involved throughout the HBO series' entire run, aside from co-creators David Benioff and D.B. Weiss. This week's episode, “A Knight of the Seven Kingdoms,” was Cogman's last as a Game of Thrones writer. “This is it for me in terms of Westeros,” Cogman tells Variety. “It’s been a beautifully cathartic thing re-watching the series recently, it’s been ten years of my life.”
