As HBO prepares for a future following the conclusion of Game of Thrones, one of the premium cable network's planned prequel spinoffs is no longer happening.
After reports surfaced in 2017 that longtime series writer and executive producer Bryan Cogman was developing a prequel spinoff to the series, Cogman confirmed his planned spinoff has since been shelved by the network. This makes Cogman's work on the final season of the main series his last with the franchise for the foreseeable future.
"I'm definitely leaving. I was developing one of the successor shows with [series creator George R.R. Martin]. George has worked with a bunch of the writers, including Jane, whose show is being done [as a pilot]. My prequel show is not happening and will not happen. HBO decided to go a different way," Cogman revealed in an interview with The Hollywood Reporter. "So, it is a goodbye. I am done with Westeros. It's wonderfully bittersweet. I'll certainly miss it, but I'm excited to go out on my own and try to be in the captain's chair of my own projects, armed with everything I've learned."
Cogman confirmed his final writing work with Game of Thrones was the most recent episode, "A Knight of Seven Kingdoms." His time with the franchise now over, Cogman has begun developing his own projects for Amazon.
Airing Sundays at 9 p.m. ET on HBO, Game of Thrones stars Peter Dinklage as Tyrion Lannister, Nikolaj Coster-Waldau as Jaime Lannister, Lena Headey as Cersei Lannister, Emilia Clarke as Daenerys Targaryen, Sophie Turner as Sansa Stark, Maisie Williams as Arya Stark and Kit Harington as Jon Snow.
