HBO has developed a bunch of Game Of Thrones prequel shows, and we know that Jane Goldman’s The Long Night is the one they’re pressing ahead with. Bryan Cogman, who worked on a different prequel idea, has confirmed that his project has been canned…

As well as serving as a producer and executive story editor on Game Of Thrones for years, Cogman has written eleven episodes of the smash hit series, including last week’s Brienne-empowering instalment,  A Night of The Seven Kingdoms.

When HBO was tasking writers with inventing prequel ideas, it’s only natural that Cogman, with all his experience on the main show, would’ve taken a pop at coming up with something.

Speaking to The Hollywood Reporter, Cogman has now confirmed that his prequel idea hasn’t been picked up, which means he’s done with the Game Of Thrones universe for now:

“I’m definitely leaving. I was developing one of the successor shows with George [R.R. Martin]. George has worked with a bunch of the writers, including Jane [Goldman], 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. I’m working with Amazon now and helping them out with their shows. 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. I’ve learned more than I could possibly imagine from eight seasons of this thing. It’s been wonderful to look back and watch some of the old episodes, and see some of our old friends at the premiere recently, and to know that we’ve done something good. We’ve done good work that people enjoy. That’s all an entertainer can ever hope for. I’m eager to start the next chapter, but a part of my heart will always live with Game of Thrones. That’s one of the reasons why this episode was so important to me. It was a goodbye and a love letter to these characters and to this cast.”

As Cogman mentioned, Jane Goldman and George R.R. Martin have been pressing ahead with The Long Night, their Game Of Thrones prequel show, which has been assembling an impressive cast for a pilot episode at HBO.

We’ll be sure to keep you posted as that show develops, and as Cogman’s future projects come to light…
