A Game of Thrones feature film is now "firmly" in development at Warner Bros., according to TheWrap, marking a significant step for a franchise that has so far confined itself to the small screen. The project has found its writer in Beau Willimon, the acclaimed creator of House of Cards and a key contributor to the Emmy-winning Disney+ series Andor, who has already submitted an initial draft of the screenplay.
According to Page Six Hollywood, which first broke the news of Willimon's involvement, the story may centre on Aegon I Targaryen — known variously as Aegon the Conqueror and Aegon the Dragon — who united six of the seven kingdoms of Westeros through conquest roughly 300 years before the events of the original television series. This would mark the first time Aegon I has been depicted on screen. As one source told Page Six Hollywood: "All of Game of Thrones stems back to him, and you've never seen him on any of the shows."
An Oscar and seven-time Emmy nominee, Willimon is best known for creating Netflix's House of Cards; his feature screenwriting credits include Mary Queen of Scots and The Ides of March. Most recently, he worked on both seasons of the Emmy-winning Andor, writing much of the Ghorman storyline in Season 2. That body of work — political intrigue, moral complexity, high-stakes consequence — maps neatly onto the Thrones universe's signature strengths. The film version is reportedly being envisioned as a mammoth, Dune-sized feature.
The commercial logic is not difficult to follow. Game of Thrones remains one of the most valuable intellectual property franchises in entertainment, and the television spinoffs have demonstrated that audience appetite for Westeros is far from exhausted. A Knight of the Seven Kingdoms was a smash hit, and House of the Dragon Season 3 looks set to finally deliver the conflict fans have been anticipating. Taking that property to cinemas would represent a bold bet on theatrical distribution at a time when Hollywood is still recalibrating after the streaming wars.
There is, however, a very significant catch. Paramount and Warner Bros. Discovery have entered into a definitive merger agreement under which Paramount will acquire WBD, paying $31.00 per share in cash. The transaction has been unanimously approved by the boards of both companies and is expected to close in Q3 2026, subject to regulatory clearances and shareholder approval. That deal, a historic Hollywood megadeal valued at $111 billion, introduces genuine uncertainty for projects currently in development at Warner Bros. Incoming management at any merged studio typically reviews the slate, and no creative attachment — no director, no cast — has yet been announced for the Thrones film.
Proponents of the project would point to one encouraging signal from the incoming regime. Paramount boss David Ellison was recently asked his favourite HBO show and cited Game of Thrones, which is seen as a good sign for both the prospective film and for the future of HBO's many prequels and sequels in development. At the same time, Game of Thrones is one of the company's crown jewels, and Paramount's CEO has pledged to release 30 films theatrically once the two media giants become one, meaning they will need plenty of material to populate their joint slates.
The franchise itself is not short of activity in the meantime. HBO has renewed the 2022 spinoff House of the Dragon for two more seasons, with the subsequent spinoff A Knight of the Seven Kingdoms premiering in January. A television spinoff exploring the events of Robert's Rebellion is also in development, and is set to debut as a stage production in the United Kingdom this summer. There have also been early conversations about a project centred on Arya Stark, following the collapse of a planned Jon Snow sequel series.
The broader question of whether the world of George R.R. Martin's creation can make a successful transition from prestige television to cinema is one the industry will be watching closely. Game of Thrones spinoffs have a history of not making it to the screen, and the Paramount-WBD merger adds another layer of corporate risk to an already complex development process. Still, a polished first draft from one of the most respected writers in prestige television is a more concrete foundation than most ambitious projects can claim at this stage. Whether the accountants at a newly merged Paramount-Warner Bros. ultimately greenlight the journey to Westeros is, for now, genuinely an open question.
