A new Game of Thrones prequel series is in the works at HBO. The show is reportedly based on GoT author George RR Martin’s Tales of Dunk and Egg novellas and is ‘high priority’. The stories are sets 90 years before A Song of Ice and Fire that served as the source material for Game of Thrones.
Reportedly, the one-hour show would follow the adventures of Ser Duncan the Tall (Dunk) and a young Aegon V Targaryen (Egg). Aegon V was the father of the Mad King, grandfather to Daenerys Targaryen, and great-grandfather to Jon Snow. Martin has published three novellas in the series so far- The Hedge Knight in 1998, The Sworn Sword in 2003, and The Mystery Knight in 2010.
No writer or director has been attached to the project as its still in early development. HBO Max already has House of Dragon in the works, another GoT prequel and is expected to land in 2022. It is based on Martin’s book Fire & Blood and is set 300 years prior to the events of the show and tells the history of House Targaryen, leading up to the civil war known as Dance of the Dragons.
If Dunk & Egg gets a series order then it will become the second prequel to follow GoT. However, there’s no guarantee as the first prequel led by Naomi Watts was cancelled after shooting a pilot episode.
