It’s official. A Game of Thrones film is happening. Beau Willimon, the creator behind House of Cards and writer of Andor, is developing the screenplay. Although details are still limited, reports suggest the story will center around the Targaryen king and dragon lord, Aegon I. In George R. R. Martin’s novels, Aegon the Conqueror, as he is also known, was the Seven Kingdoms’ first ruler to sit on the Iron Throne and founded the Westeros ruling dynasty.
Willimon has already delivered the first draft. The Wrap claims studio execs are apparently thrilled by the story, which takes place around 300 years before HBO’s TV adaptation. Momentum is moving at quite a pace. Variety revealed a title had been agreed upon in April – Game of Thrones: Aegon’s Conquest – and Warner Bros. has included it as part of its CinemaCon showcase of upcoming projects from 2027 onwards.
What Do We Know About the Upcoming Game of Thrones Movie?
According to reports, Game of Thrones: Aegon’s Conquest will act as a prequel to HBO’s eight-season fantasy drama. It’ll revolve around Aegon and his two sister-wives, Visenya and Rhaenys, who flee the apocalyptic Doom of Valyria with the world’s last three remaining dragons.
The film will be based on the book, Fire & Blood, which Martin released in 2018. In it, the first 150 years of the Targaryen dynasty are chronicled through the POV of an in-universe historian called Archmaester Gyldayn. Among the events detailed, perhaps most exciting is Aegon’s attempt to conquer Dorne in the First Dornish War, and how he builds the political foundations of the realm, ultimately unifying the Seven Kingdoms under the rule of the Iron Throne.
In terms of the talent involved, only writer Beau Willimon has been confirmed. No casting has yet taken place. And a director has not been announced. But Warner Bros. is known to want a Dune-sized theatrical event, believing, with justification, that Game of Thrones is ready for a big-screen outing.
Certainly, there’s been no letup in the franchise’s appeal despite the original TV series concluding in 2019. The two spin-offs on the small screen so far – House of the Dragon, which premiered in 2022, and this year’s A Knight of the Seven Kingdoms – have both earned strong audience ratings. Beyond TV, Game of Thrones has driven tourism to record levels in Northern Ireland, where much of it was shot, and has even inspired an official slots casino game in which the warring families, from the Starks and Lannisters to the Baratheons and the Targaryens, are featured on its various symbols.
The ongoing appeal of the IP has given Warner Bros. the confidence that a theatrical release is merited. Indeed, Willimon’s pitch was chosen by the studio over a competing television pitch by Mattson Tomlin. Given the epic scale of Aegon’s adventures and the large-scale wars he finds himself at the heart of, expect Warner Bros. to sanction a hefty budget in the region of the $165 million it put into Dune: Part One.
A Monumental Theatrical Experience
Game of Thrones: Aegon’s Conquest promises a lot. It already has a talented writer on board, and Warner Bros. is keen to develop a major theatrical event for what is likely to be one of its tentpole blockbusters in the coming years.
If handled well, the film could give audiences the kind of scale, spectacle, and political intrigue that made Game of Thrones a global phenomenon in the first place. Aegon’s story has all the ingredients needed for a major cinematic event: dragon warfare, fractured kingdoms, family ambition, and the violent birth of the Iron Throne. It also gives Warner Bros. a chance to expand Westeros beyond television and prove that George R. R. Martin’s world can command the big screen as powerfully as it once dominated Sunday-night TV.
For now, much remains unknown, from casting and direction to release timing. But with momentum building and the studio clearly positioning Aegon’s Conquest as a major priority, the project is already shaping up to be one of the most closely watched fantasy films on the horizon. For longtime fans, the chance to see the conquest of Westeros unfold in cinemas could be the most exciting return to the Seven Kingdoms yet.
