"A Knight of the Seven Kingdoms: The Hedge Knight" Gets 2025 Release Window

The “Game of Thrones” prequel based on George R.R. Martin’s “Dunk and Egg” books is getting closer to their HBO debut.

On Friday, Warner Bros. Discovery CEO David Zaslav gave an update on the next Game of Thrones spinoff series.

“[Creator and executive producer] George R.R. Martin is in pre-production for the new spinoff, "A Knight of the Seven Kingdoms", which will premiere in late 2025 on Max,” Zaslav said.

The series is expected to begin production sometime this year. It is based on the series of fantasy novellas by Martin and follows the adventures of Ser Duncan the Tall (Dunk) and a young Aegon V Targaryen (Egg) 90 years prior to the events of “A Song of Ice and Fire.”

It takes place a century before the events of "Game of Thrones", and is centered around two unlikely heroes wandering Westeros… a young, naïve but courageous knight, Ser Duncan the Tall, and his diminutive squire, Egg.

Set in an age when the Targaryen line still holds the Iron Throne and the memory of the last dragon has not yet passed from living memory, great destinies, powerful foes, and dangerous exploits all await these improbable and incomparable friends.

Martin will serve as writer and executive producer, as well as Ira Parker, who was a co-executive producer on Season 1 of “House of the Dragon.” “Game of Thrones” and “House of the Dragon” vets Ryan Condal and Vince Gerardis will serve as executive producers.

Martin has published three novellas in the “Tales of Dunk and Egg” series to date: “The Hedge Knight” in 1998, “The Sworn Sword” in 2003, and “The Mystery Knight” in 2010.

The novellas were collected and published together as “A Knight of the Seven Kingdoms” in 2015.

This is the latest Westeros-based project at HBO. Following the global success of “Game of Thrones,” the premium cabler moved to develop a number of series set in the world created by Martin. Of the numerous projects announced as being in development over the years, the only other one to move forward before this has been “House of the Dragon”.

“House of the Dragon” premiered its first season in August 2022, earning a speedy Season 2 renewal less than a week after it launched. Season 2 is currently in production. 

HBO is also developing a series set during Aegon’s Conquest from "The Batman: Part II" writer Mattson Tomlin. Other ideas set in Martin’s fantasy world are also in development, though only House of the Dragon and Knight of the Seven Kingdoms have been greenlit.

“Looking ahead, we’ve got one of the best lineups in the history of HBO,” Zaslav continued. “This next quarter, we’ll have Hacks and House of the Dragon, followed by DC’s The Penguin and the new Dune series. Then in 2025, we’ll kick off the year with the new season of The White Lotus, followed by The Last of Us and Euphoria, just to name a few.”
