HBO will have 'Game of Thrones' spinoffs on the air at least through 2028

HBO won't let you go even a year without a "Game of Thrones" spinoff for the foreseeable future.

Casey Bloys, chairman and CEO of HBO and HBO Max, announced during a Nov. 20 event at NYC's Hudson Yards that the network's two "Thrones" spinoff series "House of the Dragon" and "A Knight of the Seven Kingdoms" will each be coming back for more seasons.

"Dragon," already set for a third season on HBO debuting in summer of 2026, has officially been renewed for a fourth season, now set for 2028. It stars Emma D'Arcy, Olivia Cooke and Matt Smith as scheming royals and politicians 300 years before the events of "Thrones."

"Knight," a new series premiering on HBO Jan. 18 (10 ET/PT), will be guaranteed a second-go-round in 2027.

Author George R.R. Martin previewed his passion project "Knight" in October at New York Comic Con, revealing to fans more about what the unusual spinoff will entail.

"One of the things that one of the (critics) said was, 'Here it is, another fantasy, and we get to hear more about kings and lords, and lords and kings. Nobody ever writes about the common people' – the smallfolk, as I call them," Martin said. "And that resonated with me. Believe it or not, occasionally, we do listen to some of the critics, if they know what they're talking about."

The prequel series, which follows the adventures of knight Ser Duncan the Tall (Peter Claffey) and his young squire Egg (Dexter Sol Ansell), is set after "House of the Dragon" but before "Game of Thrones," though fans should expect some key differences from those two shows.

"Following Dunk on this journey should be a very grounded, gritty, earthy, ground up sort of feel," Ira Parker, who created "A Knight of the Seven Kingdoms" with Martin, said during a panel at New York Comic Con.

"We've never had this perspective before," Parker added.
