HBO's Game of Thrones franchise is the apex predator of the fantasy TV world, and it's an empire that has only expanded with other hit spin-offs like House of the Dragon and A Knight of the Seven Kingdoms. The television space is firmly under the franchise's control, but there is one territory the brutal adult fantasy saga hasn't yet conquered — movie theaters. "Conquered" is actually the opportune word here, as at CinemaCon 2026, Warner Bros. officially revealed plans for the first-ever Game of Thrones movie, with the official title of Aegon's Conquest. Considering CinemaCon is an expo that almost exclusively caters to theatrically released features, this quietly seems to confirm that Aegon's Conquest will be the first Game of Thrones story to hit the big screen.
