Just as fans can't get enough of Game of Thrones, neither can HBO, which is reportedly begun development on a fifth potential prequel series.
According to Variety, the project will be written by series veteran Bryan Cogman, who's been involved with Game of Thrones since Season 1, most recently as a writer and co-executive producer.
Although speculation about potential spinoffs of the hit fantasy drama were long dismissed, it was reported in May that HBO is developing four possible prequels, with author George R.R. Martin later confirming that a fifth project was in the works. “None of these new shows will be ‘spinning off’ from GOT in the traditional sense," he wrote. “Every one of the concepts under discussion is a prequel, rather than a sequel. Some may not even be set on Westeros.”
It's already been reported that Max Borenstein (Kong: Skull Island), Jane Goldman (Kingsman: The Golden Circle), Brian Helgeland (Legend) and Carly Wray (Mad Men, The Leftovers) are involved in the other four series.
None of the main cast of the series will be involved in these projects. Characters like Ser Duncan the Tall, Aegon the Unlikely and Dunk and Egg have been ruled out as subjects for these shows as well.
Game of Thrones will conclude with its eighth season, expected to air in 2018 or 2019.
