The Game of Thrones movie is officially happening, and it will tell the story of one of the most important events in George R.R. Martin's fantasy lore

Warner Bros. has announced that the Game of Thrones movie is definitely happening, and we even know what it will be about.

The movie was first reported in March 2026, with the report indicating the film would possibly be about Aegon's Conquest. Thanks to the new update, we know the movie will definitely be about this seismic event in Westerosi history.

Per Variety, the movie's working title is Game of Thrones: Aegon's Conquest, and it was included on the Warner Bros. slate at CinemaCon in the "2027 and beyond" category.

This Aegon is Aegon I, the original Targaryen king who conquered Westeros and united it under his rule, along with his two sister-wives Visenya and Rhaenys.

House of the Dragon has revealed that Aegon did this thanks to the prophecy of the prince that was promised, which meant he foresaw the threat of the White Walkers – and that a Targaryen ruler had to be on the throne to prevent the apocalypse.

Not much else is known about the film just yet, though it was previously reported that Aegon's Conquest was being developed both as a "mammoth Dune-sized feature film" and as a TV show. The Batman 2 co-writer Mattson Tomlin was working on the show, while Andor scribe Beau Willimon is working on the film. Judging by this latest update, the show is no more.

This announcement comes hot on the heels of George R.R. Martin's publisher denying a rumor that The Winds of Winter would release this year, as the wait for the sixth book is about to surpass the wait for all five books combined.

But, if you're missing Westeros, there's plenty coming very soon to tide you over. House of the Dragon season 3 lands this summer, while A Knight of the Seven Kingdoms season 2 will arrive in 2027.

Plus, the stage play Game of Thrones: The Mad King is set to open this July in the UK's Stratford-upon-Avon, telling the story of the pivotal tourney at Harrenhaal, when Rhaegar Targaryen crowned Lyanna Stark the queen of love and beauty.

There's no release date for the Game of Thrones movie just yet, but, while you wait, check out our guide to all the upcoming Game of Thrones movies and shows.
