Warner Bros. Discovery CEO David Zaslav had a bunch of updates this morning about upcoming content on Max, including the next “Game Of Thrones” spinoff. THR reports that Zaslav revealed the planned premiere date for “A Knight Of The Seven Kingdom: The Hedge Knight,” which won’t be for a while. So good thing that “House Of The Dragon” Season 2 arrives later this year to tide fans over.

“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 on a fourth-quarter earnings call this morning. Production on the series should begin sometime this year, if HBO wants to hit that release date. But remember that “House Of The Dragon” Season 2 doesn’t have an official release date yet, only a vague “early Summer 2024” update, so things could switch around.
The third of many “Game Of Thrones” spinoffs in development, “The Hedge Knight” adapts Martin’s “Dunk And Egg” novellas, about the quests of Ser Duncan the Tall and future Westerosi king Aegon V Targaryen. The pair’s exploits occur about a century before the events of Martin’s novels and David Benioff and D.B. Weiss‘ original series; so consider this series a prequel like “House Of The Dragon.”
Here’s an official synopsis for “The Hedge Knight,” courtesy of HBO: 
A century before the events of “Game of Thrones,” two unlikely heroes wandered 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.
Don’t confuse the adventures of Dunk and Egg for another “Game Of Thrones” prequel series about Aegon Targaryen potentially on the way. That series, about Aegon’s conquest of Westeros, found a writer earlier this month in “The Batman Part II” scribe Mattson Tomlin. But there’s no guarantee the show will get greenlit; its future likely depends on the success of “House Of The Dragon” and “The Hedge Knight.”
And the same goes for the myriad other “Game Of Thrones” spinoffs HBO has in development.  Kit Harington‘s Jon Snow series feels the most likely to hit production out of those, but that’s several years away at this point. So for now, “Game Of Thrones” will have to settle for “The Hedge Knight” and its planned release late next year.
