Amazon MGM Studios is no longer moving forward with the Stargate television series developed by Martin Gero. The project was officially announced in November 2025, but it was dropped in June 2026 before casting or filming began. However, Amazon has not completely abandoned the franchise, as the studio is reportedly searching for a new writer to develop another version.
That distinction is important. The Martin Gero series has been canceled, but the possibility of a different Stargate show on Prime Video remains alive.

Amazon Has Canceled Martin Gero’s Stargate Series
Amazon MGM Studios originally announced a new Stargate television series on November 19, 2025. Martin Gero, who previously worked across Stargate SG-1, Stargate Atlantis and Stargate Universe, was selected to write, executive produce and serve as showrunner.
The announced production team also connected several important figures from the franchise’s history. Original movie creators Dean Devlin and Roland Emmerich were attached as executive producers, while longtime television producers Brad Wright and Joe Mallozzi were named consulting producers.
That announcement gave fans reason to believe the franchise was finally preparing for a meaningful television comeback. However, on June 2, 2026, reports confirmed that Amazon had decided not to proceed with Gero’s version of the show.
Why Was the New Stargate Series Canceled?
Amazon has not released a detailed public explanation outlining every reason behind the decision. Industry reporting claimed that executives were concerned Gero’s proposed series might appeal primarily to established Stargate fans rather than attracting a sufficiently broad audience.
Joe Mallozzi pushed back against that reported concern. He said the creative team had been conscious of the need to welcome new viewers while respecting the existing continuity. According to Mallozzi, Gero spent approximately two years developing a series that offered a fresh entry point without disregarding the franchise’s history.
This disagreement has become central to the fan discussion. Supporters argue that Gero’s experience within the franchise made him particularly well suited to balance accessibility with continuity. Others acknowledge that Amazon may be looking for a concept capable of competing as a large international streaming production.
What Martin Gero’s Stargate Series Would Have Been
Very little official plot information was released before the project was canceled. However, Gero indicated that the series was not intended to erase or undo the events of the earlier television shows.
The proposed show would have functioned as a new chapter within the established Stargate universe while remaining understandable to people who had never watched hundreds of earlier episodes. That approach could have allowed familiar characters, organizations and events to exist alongside a new central cast.
Mallozzi later confirmed that the concept would have introduced new worlds and characters while also providing opportunities to revisit familiar faces from the franchise’s past.
Unfortunately, the production did not advance far enough for a cast to be announced. Gero had previously made it clear that the team was not yet close to casting when discussing the project in late 2025.
Is Amazon Still Making a New Stargate Show?
Possibly, but it will not be the version developed by Martin Gero.
A July 2026 industry update reported that Amazon is searching for a new writer to tackle the Stargate intellectual property. This suggests that Amazon MGM Studios remains interested in reviving the franchise, even after abandoning the previously greenlit series.
No replacement writer, showrunner or production team has been announced. Amazon has also not confirmed whether the next concept will be a complete reboot, a continuation of the television canon, a new adaptation of the original movie or an unrelated story built around the Stargate technology.
Until another project receives an official series order, it would be inaccurate to say that a new Stargate show is definitely coming to Prime Video. The most accurate description is that Amazon is exploring another attempt at developing the franchise.
Why Fans Are Supporting the Canceled Version
The cancellation generated a strong reaction because Gero’s involvement had reassured many longtime viewers. He had firsthand experience with the franchise, while Brad Wright and Joe Mallozzi brought additional knowledge of its characters, mythology and television identity.
Fans have promoted the #SaveStargate campaign and called for Amazon to reconsider the decision. The latest report that another writer is being sought has renewed frustration among viewers who believe the studio already had an experienced creative team in place.
The reaction also demonstrates the challenge Amazon faces. A new series must be accessible enough to attract viewers unfamiliar with the franchise while giving existing fans a reason to invest in another interpretation.
Why Stargate Still Matters
The franchise began with Roland Emmerich’s 1994 film, written by Emmerich and Dean Devlin. Its central concept involved an ancient ring-shaped device capable of creating a wormhole between distant worlds.
That idea was significantly expanded by Stargate SG-1, which began in 1997 and continued for 10 seasons. The series followed an Earth-based military and scientific team exploring other planets, forming alliances and confronting threats including the Goa’uld, Replicators and Ori.
The television universe later expanded through Stargate Atlantis, Stargate Universe, direct-to-video movies and the prequel web series Stargate Origins. Together, these productions built a mythology combining military science fiction, ancient cultures, interplanetary exploration, humor and found-family storytelling.
Unlike many science-fiction properties, Stargate frequently presented extraordinary cosmic discoveries through the perspective of recognizable, present-day human characters. That approachable structure helped the franchise support both standalone adventures and larger serialized conflicts.
What a Future Stargate Series Needs to Get Right
A clear entry point for new viewers
A new audience should be able to understand the central characters, the Stargate program and the primary conflict without completing an extensive franchise rewatch.
Respect for the established universe
Accessibility does not require erasing earlier stories. Existing continuity could provide history, depth and opportunities for carefully selected appearances by legacy characters.
Strong character chemistry
The earlier shows succeeded because viewers cared about the teams passing through the gate. Visual effects can make alien worlds more convincing, but relationships, humor and emotional stakes will determine whether audiences remain invested.
A sense of exploration
The franchise works best when the Stargate leads somewhere genuinely unexpected. A future adaptation should preserve the excitement of encountering unfamiliar worlds, cultures, technologies and dangers.
A consistent creative identity
Amazon must decide whether it wants a military adventure, a darker serialized drama, an optimistic exploration series or a combination of these approaches. Trying to imitate several competing science-fiction franchises could make the new show feel less distinctive.
Could Original Stargate Actors Return?
No legacy actors were officially cast in Martin Gero’s canceled series. While Mallozzi indicated that the proposed story could have revisited familiar faces, no specific appearances were confirmed.
The status of potential returning actors is now even less certain because a different writer may create an entirely different premise. Any reports naming Richard Dean Anderson, Michael Shanks, Amanda Tapping, Christopher Judge, Joe Flanigan or other franchise stars should therefore be treated as speculation unless Amazon announces their involvement.
Does the New Stargate Series Have a Release Date?
No. The canceled Martin Gero series never received a premiere date, and Amazon’s potential replacement project remains at the search-for-a-writer stage.
Previous estimates suggesting a 2027 or 2028 release were based on the expected production schedule of Gero’s version. Those estimates are no longer reliable. A realistic release window cannot be discussed until Amazon selects a writer, approves a concept and formally orders another series.
What Happens Next?
The next major development will likely be the appointment of a new writer or showrunner. That announcement should provide the first indication of whether Amazon plans to continue the existing television mythology or restart Stargate for a completely new audience.
After that, fans should watch for confirmation of a series order, producers, plot details, filming location and casting. Until those steps occur, the franchise’s television future remains uncertain.
Final Thoughts
Amazon’s decision to cancel Martin Gero’s Stargate series brought an anticipated revival to an abrupt end. The project appeared to offer a rare combination of franchise experience, respect for established canon and a path for new viewers to enter the universe.
However, the cancellation does not necessarily mean the Stargate has permanently closed. Amazon is reportedly searching for another writer, showing that the studio still sees potential in the property.
The central question is no longer when Martin Gero’s series will arrive. It is whether Amazon’s next approach can earn the confidence of longtime fans while building a new audience capable of supporting the franchise for years to come.
Yes. Amazon decided not to move forward with the Stargate series developed by Martin Gero. The project had originally been greenlit in November 2025.
Not necessarily. Although Gero’s version was canceled, Amazon is reportedly searching for a new writer to develop another take on the franchise.
Industry reports claimed Amazon was concerned that the concept might not appeal broadly enough beyond existing fans. Consulting producer Joe Mallozzi disputed that characterization and said the team had developed the series for both new and longtime viewers.
No replacement writer has been announced. As of July 2026, the search for a new writer was reportedly underway.
No returning cast members have been confirmed. Any legacy appearances will depend on the premise selected for Amazon’s next version.
There is currently no release date. Amazon has not officially ordered a replacement series, and the canceled Martin Gero project will not be released.
