According to Variety, the network is looking to follow up on the success of Game of Thrones by devoting a show to theTales of Dunk and Egg series.
George RR Martin has authored three novellas that make up theTales of Dunk and Egg. The Hedge Knight was released in 1998; The Sworn Sword in 2003, and The Mystery Knight in 2010.
All three were compiled into one volume, A Knight of the Seven Kingdoms, released in 2015.
Set 90 years before the events depicted in the A Song of Ice and Fire novels (which provided the basis for Game of Thrones), the Tales of Dunk and Egg tell the stories of Ser Duncan the Tall (the eponymous Dunk) and Aegon V Targaryen (also known as Egg).
According to Variety, no cast or writer is attached to the project so far.
Game of Thrones aired for eight series between 2010 and 2018. Its finale, The Iron Throne, drew 19.3m US viewers in May 2019.
The fantasy drama television series, created by David Benioff and DB Weiss, was a massive success for HBO, sparking discourse and fan theories around the world.
The Independent has contacted HBO for more information.
Martin has published five novels as part of the A Song of Ice and Fire series, between 1996 and 2011. Two more are planned: The Winds of Winter and A Dream of Spring.
In an update in June 2020, Martin assured readers he was hard at work on The Winds of Winter, writing that he was “making steady progress” but adding: “It’s going to be a huge book, and I still have a long way to go”.
