Deadline reports that Game of Thrones: Aegon’s Conquest is scheduled to reach theaters on June 1, 2029. Owen Harris is attached to direct, with Beau Willimon writing the screenplay.
We reported on Willimon’s involvement in March, when the subject of the film was still speculation. Warner Bros. revealed its working title in April. Now the project has both a date and a director, which means it’s rolling along.
Last month, news broke that Beau Willamon (House of Cards, Andor) was working on a Game of Thrones-related project, with speculation that it was related to Aegon the Conqueror and his conquest of the Seven Kingdoms. At CinemaCon 2026, where the studios present their upcoming films and slates to the press and exhibitors, Warner Brothers confirmed the news when it made a presentation related to its plans for “2027 and beyond”, where Variety reports that the working title Game of Thrones: Aegon’s Conquest was revealed.

Interesting news broke last night that HBO is gearing up to explore the extensive history of Westeros with a new spinoff series centered around Aegon’s Conquest. According to a report from James Hibberd and Borys Kit for The Hollywood Reporter, the network has enlisted much-in-demand writer Mattson Tomlin to develop the project.
Last year, we noted news out of Variety that HBO had starting looking into bringing Aegon’s Conquest to the small screen (and, perhaps, even the big screen—a theatrical lead-in was under discussion) and actively sought a writer to head the development of this thrilling prequel series. That search seems to have ended.

Variety has an exclusive scoop: HBO is actively considering a TV show about Aegon’s Conquest, which would take the Game of Thrones franchise back to the very beginning of the establishment of the Targaryen dynasty in Westeros. Per Variety:
As the project is in its very early stages, no writer is currently attached, though sources say that the search is underway as HBO is keen to move forward and get it into development. Sources also say that there may be a feature component to the project, i.e. HBO and Warner Bros. would produce a feature film that would then lead into the potential series, though plans remain in flux at present.
The full story of Aegon’s Conquest was first told in The World of Ice and Fire, which was later expanded with more information about the aftermath in Fire & Blood.
