🔍Deep Dive Analysis
Amazon MGM Studios canceled the new Stargate series that was greenlit in November 2025. The project, led by Martin Gero, a veteran writer from previous Stargate shows like 'Stargate: Atlantis', was well into development, having completed a 20-week writers' room and with pre-production underway in London.
Reports from Variety and other outlets indicate that Amazon executives were concerned Gero's take on the series would not have broad appeal beyond the franchise's dedicated fanbase. This decision reportedly followed a corporate restructuring at Amazon MGM Studios, where executives who initially championed the project were no longer in place. Joseph Mallozzi, a consulting producer on the series and a long-time Stargate creative, publicly disputed this reasoning, stating the team was "ever mindful of creating a show that would have broad appeal" while respecting existing canon.
The journey for a new Stargate series under Amazon began in 2022 when Amazon acquired MGM, thereby gaining control of the Stargate intellectual property. The official greenlight for Gero's series came in November 2025, generating significant excitement among fans. The writers' room commenced in January 2026, and by February 2026, London was selected as the main production hub with filming slated for Fall 2026. However, the sudden cancellation in early June 2026 halted all progress.
The consequences of this cancellation are a significant disappointment for the Stargate fanbase and the creative team, who had dedicated two years to developing the project. It leaves the immediate future of the franchise uncertain, though Amazon has expressed continued interest in exploring the IP. As of June 5, 2026, the specific Stargate series developed by Martin Gero is officially canceled. Amazon MGM Studios is reportedly still exploring other avenues to revive the Stargate franchise, potentially with a new creative team and a different approach, possibly a full reboot that might not connect to the prior established canon.
