HBO Working on Another Game of Thrones Spin-Off Based on the Targaryen Line

HBO is still working on several more Game of Thrones spin-offs including one “very promising” show focused on the Targaryen line, though nothing has been greenlit as of yet.

Francesca Orsi, head of drama series and films at HBO, suggested to Deadline that, despite both current Game of Thrones spin-offs — House of the Dragon and A Knight of the Seven Kingdoms — focusing on Daenerys Targaryen’s ancestors, the next furthest along show is too.

“We have other spin-offs that we’re working on right now, one of which — which I won’t get into — is very promising, and is still the Targaryen line,” Orsi said. “There’s a number of other spin-offs. We can’t really guarantee what’s going to go forward, but we are very big budget on the other ones.”

HBO isn’t just looking to expand Game of Thrones with further television series but also in the full scale movie space, as HBO and Max CEO Casey Bloys said in November it’s working to get a film off the ground with George R.R. Martin.

A series isn’t fully official until its greenlit, however, as HBO has so far developed myriad shows that never saw the light of day.

Cancelled series so far include a prequel based on an in-world apocalypse called The Long Night, which HBO scrapped after spending $30 million on a pilot episode, a show called 10,000 Ships which would focus on a sea-faring city, a mysterious Braavos series which Martin plans on continuing in writing form himself, and a sequel starring Kit Harington as Jon Snow.

Martin recently appeared to tease a return of Arya Stark actress Maisie Williams too, though nothing has been said officially about such a comeback.
