Game of Thrones Producer Developing Prequel Series. Share. Bryan Cogman has been with the show since Season 1. By Jonathon Dornbush. K7 Antivirus Full Form. A fifth Game of Thrones prequel in development is being produced by a longtime producer on the existing HBO series, a new report confirms. EW has revealed that Game of Thrones co executive producer Bryan Cogman is writing a prequel series in addition to the other four we previously learned HBO was developing and has worked closely with George R. R. Martin in the projects development. Martin is also involved in the creation of some of these other prequel spinoffs. Cogman has been with the series since its inaugural season, during which he was an assistant to showrunners David Benioff and Dan Weiss. He has gone on to be one of the most frequently credited writers on the show, including Season 7s Stormborn, Season 5s Unbowed, Unbent, Unbroken, and Season 4s Oathkeeper. Unfortunately, no specific story details about Cogmans prequel series are known at this time beyond the previously announced parameters all the prequels are set before the events of Game of Thrones and do not involve any of the shows current cast. None of these in development prequels are guaranteed to air, and there is no target air date for any of the series. IGN recently spoke with a writer of another prequel series, Jane Goldman, about how her series will be recognizable as a past event to fans. Any of the prequels series, should they air, are not expected to come until after Game of Thrones eighth and final season, for which HBO is reportedly filming multiple endings to avoid leaks.
