Amazon MGM scraps Martin Gero's Stargate

Amazon MGM Studios has scrapped Martin Gero’s planned “Stargate” series, ending a project that had already received a series order and moved into pre-production. Trade outlets Deadline and Variety reported the decision on June 2, citing people familiar with the matter. The project had been announced by Amazon in November 2025 as a new original series for Prime Video. No plot details were ever publicly released. ### How far had the series actually gotten? Deadline reported the show had completed a 20-week writers room and was in pre-production in the United Kingdom when Amazon pulled the plug. GateWorld, which closely tracks the franchise, said filming had been expected to begin this fall. That puts the cancellation well beyond an early concept stage and into active development. (deadline.com) November 2025 was when Amazon publicly unveiled the project. In its announcement, the company said Gero would write and serve as showrunner on a “new original series” for Prime Video. Amazon also tied the project directly to the MGM-owned franchise it acquired through its MGM deal. ### Who was attached to make it? (deadline.com) Martin Gero was the central creative figure on the series. Amazon said in November that he would write and showrun the project, and trade reports described him as a veteran of earlier “Stargate” television entries including “Stargate SG-1” and “Stargate Atlantis.” Variety reported the series had been set up at Amazon as a high-profile return for the franchise, but the company never released story details, casting information or a production start date. (aboutamazon.com) That left much of the project’s shape to trade reporting and franchise outlets rather than formal studio materials. ### Why did Amazon walk away after ordering it? (aboutamazon.com) Deadline reported the explanation given internally was that the project’s vision and creative direction no longer aligned with Amazon’s programming strategy. Variety reported that Amazon executives had concerns about whether the show would appeal beyond the existing “Stargate” fan base. Those accounts came from the trades’ unnamed sources, and Amazon had not publicly laid out a fuller explanation in the materials reviewed. (variety.com) The timing also matters. Deadline described the series as a casualty of leadership changes at Amazon MGM Studios, placing the decision in the context of broader shifts inside the studio rather than any publicly disclosed issue with scripts, casting or production logistics. ### What kind of Stargate show was this supposed to be? (deadline.com) Amazon’s November announcement called it a “new original series,” but did not say whether it would continue prior storylines. Reporting around the time of the greenlight showed the project being framed as a fresh entry in the franchise rather than a simple rerun of earlier shows. (deadline.com) Because Amazon never released a synopsis, the public record on the show’s premise remains thin. What is clear is that the company had moved ahead far enough to staff a writers room and start pre-production before reversing course. ### What happens to Stargate now? As of June 3, Amazon MGM Studios had not announced a replacement “Stargate” series, film or revised development plan in the materials reviewed. (aboutamazon.com) The last formal public milestone remains Amazon’s November 2025 announcement, and the newest milestone is the June 2 decision to stop Gero’s version from moving forward. Any next step is likely to come from Amazon MGM Studios or Prime Video, which still control the franchise’s current screen future. (deadline.com)
