The writer for the rumoured fifth Game of Thrones prequel has been announced – and it’s GoT’s veteran writer and executive producer Bryan Cogman.


As HBO looks to get the most out of George RR Martin’s fantasy world once the main show wraps up with season eight, the number of spin-off series has expanded from the original four to include one more.

It’s been in the works for a while. Back in May, George RR Martin teased on his blog: “We had four scripts in development when I arrived in LA last week, but by the time I left we had five. We have added a fifth writer to the original four.”

At the time he refused to say who this mysterious writer was, but he did hint that this was someone who “knows and loves Westeros” already.

Cogman currently serves as co-executive producer and has also written ten Game of Thrones episodes, including season seven’s Stormborn.

HBO confirmed earlier this year that it had already signed deals with four writers to create four spin-off series. Godzilla’s Max Borenstein, Kingsman’s Jane Goldman, A Knight’s Tale’s Brian Helgeland and Westworld’s Carly Wray have all been tasked with finding stories to tell in the Game of Thrones universe.


The series is currently in early development, according to Deadline.
