Warner Bros. has scheduled the theatrical debut of Game of Thrones: Aegon’s Conquest for June 2029, formalizing the release timetable on September 29, 2026. The cinematic project represents the first feature-length motion picture set within the fantasy continent of Westeros, with British filmmaker Owen Harris attached to direct from a screenplay penned by Beau Willimon.
The feature will focus on the historic campaign led by Aegon I Targaryen alongside his sister-wives, Visenya and Rhaenys, to conquer and unite the disparate realms of the continent approximately three centuries before the events of the flagship television series. Journalist Rebecca Rubin documented the official announcement by observing that winter is coming to the big screen in the summer of 2029.
Filmmakers Owen Harris and Beau Willimon lead creative development
Harris steps into the director’s chair following his role as director and executive producer on the debut season of A Knight of the Seven Kingdoms, another television adaptation expanding the literary creations of author George R.R. Martin. Across his prior screen credits, Harris directed installments of the anthology series Black Mirror, the 2019 reimagining of The Twilight Zone, and episodes of Brave New World featuring actor Alden Ehrenreich. Willimon established the political thriller series House of Cards for streaming platform Netflix and contributed extensively to the writing staff of the Star Wars spinoff series Andor on Disney+.

Westerosi unification under dragonlord Aegon I Targaryen
The narrative will chart the strategic deployment of dragon power by Aegon I Targaryen as he subdued competing dynasties to unite six of the realm’s seven constituent territories, creating the governing bloodline that led centuries later to Daenerys Targaryen, portrayed by Emilia Clarke across eight seasons between 2011 and 2019. These military maneuvers and territorial conflicts were detailed in Fire & Blood, the companion volume published by Martin in 2018. Studio parent Warner Bros. Discovery previously confirmed development of a theatrical entry at the CinemaCon convention staged in April 2026.
Conflicting calendar reports emerge regarding early June 2029 rollout

Conversely, parallel media reports listed Wednesday, June 6, 2029, as the distribution target. The studio has not issued a formal clarification to address the five-day divergence between the two reported dates.
