The Game of Thrones universe finally has a date for its first theatrical movie. Warner Bros. has scheduled Game of Thrones: Aegon’s Conquest for summer 2029, with multiple reports citing a June 1, 2029 theatrical release. The film will be directed by A Knight of the Seven Kingdoms filmmaker Owen Harris from a screenplay by Andor and House of Cards writer Beau Willimon.
That makes Aegon’s Conquest a particularly important expansion for George R.R. Martin’s fantasy franchise. Until now, Westeros has primarily been a television property through Game of Thrones, House of the Dragon and A Knight of the Seven Kingdoms. The new project will be the franchise’s first feature film designed for theatrical release.
One detail is worth flagging: while Warner Bros.’ date is reported as June 1 by TheWrap, the Los Angeles Times, Entertainment Weekly and other outlets, Variety Australia currently lists June 6, 2029. Unless Warner Bros. issues a further scheduling update, June 1 is the date most consistently tied to the studio announcement.
‘Aegon’s Conquest’ goes further back than ‘House of the Dragon’
Casting has not yet been announced, and Warner Bros. has revealed very little about the screenplay. The title, however, makes the historical period difficult to mistake.
Aegon I Targaryen — better known as Aegon the Conqueror — was the Targaryen ruler who, alongside his sister-wives Visenya and Rhaenys, used the dragons Balerion, Vhagar and Meraxes to conquer most of Westeros and establish the dynasty that would rule for generations. His story appears in Martin’s Fire & Blood.
Chronologically, that pushes the movie well before House of the Dragon. The HBO series begins more than a century after Aegon’s conquest, when disputes over the Targaryen succession eventually erupt into the civil war known as the Dance of the Dragons.
The distinction matters because audiences have heard Aegon the Conqueror’s name throughout the franchise without actually seeing the original Aegon portrayed on screen. Characters including Aegon II, the future Aegon V and even Jon Snow have carried the same name, but the dynasty’s founder has remained a historical figure rather than an on-screen character.
Aegon’s Conquest therefore has an unusual advantage for a prequel: viewers already know what Aegon ultimately achieves, but much of the actual campaign remains untouched by HBO’s existing shows.
The director already has experience in Westeros
Owen Harris is not entering the franchise cold. He directed three episodes of A Knight of the Seven Kingdoms, including its Trial of Seven storyline, and also served as an executive producer on the HBO series. Outside Westeros, his credits include Black Mirror, where he directed episodes including “San Junipero,” as well as Brave New World and The Twilight Zone.
Willimon brings a different set of credentials. He created Netflix’s House of Cards and later wrote for Andor, a series frequently built around political maneuvering, rebellion and competing power structures — material that naturally overlaps with the kind of political conflict associated with Westeros. Warner Bros. first publicly revealed the film’s working title and Willimon’s involvement during CinemaCon in April 2026.
The director-writer combination suggests Warner Bros. is treating the project as more than a simple extension of the television shows.
Warner Bros. is turning Westeros into a theatrical franchise
That may ultimately be the more important part of the announcement.
There had been discussion about a Game of Thrones movie long before Aegon’s Conquest became a concrete project. But the original series remained firmly on television through its 2019 finale. Warner Bros. placing Aegon’s story on its theatrical slate changes the scale of the franchise and creates a possible path for other Westerosi stories to eventually move between HBO and cinemas.
The studio was already signalling that ambition earlier in 2026. At CinemaCon, Aegon’s Conquest appeared among Warner Bros.’ “2027 and beyond” films, and the company later referenced it as a theatrical event film in its longer-term slate.
There is still plenty Warner Bros. has not disclosed. No actor has been announced for Aegon, Visenya or Rhaenys, production dates remain unclear, and an official detailed synopsis has yet to be released.
But the most important pieces are now in place: Game of Thrones: Aegon’s Conquest has a director, a writer and a summer 2029 theatrical window. For a franchise that spent its first 18 years of screen life on television, Aegon the Conqueror will now be the character tasked with taking Westeros somewhere it has never gone before — the big screen.
