Here’s something worth thinking about as Amazon MGM Studios gears up for a brand new Stargate series: a movie that Roger Ebert once called out by name as evidence of cinema at its worst somehow spawned over 15 years of television, 364 episodes across three live-action series, two direct-to-DVD films, and a Guinness World Record. That’s not a franchise. That’s a miracle.

The new series, announced in November 2025 and led by franchise veteran Martin Gero, is being described as accessible to new viewers while not rebooting the established mythology. Which raises a genuinely interesting question: how do you sell new audiences on something this sprawling? And to answer that, it helps to understand how Stargate got so sprawling in the first place.

The Movie That Almost Wasn’t Enough

The 1994 film Stargate, directed by Roland Emmerich and co-written with Dean Devlin, is a movie that works better in premise than it does in execution… and the premise is genuinely great. An ancient ring-shaped device, unearthed in Egypt, turns out to be an alien wormhole generator capable of transporting people across the cosmos. A linguist (James Spader) and a soldier (Kurt Russell) step through it together and end up on a desert planet where a race of enslaved humans worship a parasitic alien who has been posing as the Egyptian sun god Ra.

That’s a strong hook. And audiences agreed. The film opened to $16.7 million in its first weekend, setting what was then a record for an October opening, and went on to gross $196.6 million worldwide against a $55 million budget. Critics were less enthusiastic. Ebert awarded it one out of four stars. Rotten Tomatoes would eventually settle it at a middling 53%. The consensus, roughly, was that the film had a great idea and didn’t quite know what to do with it.

Emmerich and Devlin had written Stargate as the first film in a trilogy. The second entry was supposed to venture into a different mythology entirely, with the third pulling all the threads together. None of that happened. The two went off to make Independence Day, and MGM was left holding a property with a fascinating premise, a built-in audience that wanted more, and no sequel in sight.

So they did what studios sometimes do when a film franchise stalls: they handed it to television.

The TV Gambit

In 1997, Stargate SG-1 premiered on Showtime, co-created by Brad Wright and Jonathan Glassner. The episode count at the end of its run: 214, spread across ten seasons. It became, briefly and officially, the longest-running North American science fiction series in television history, surpassing The X-Files. That record was eventually broken by Smallville, but the point stands — a movie that nobody expected much from turned into one of the most durable properties in sci-fi TV history.

How? A few things.

First, the show made smart use of what the film left behind while quietly rewriting the parts that didn’t work. The Stargate itself, that ring-shaped wormhole device, is one of the more elegant science fiction concepts to make it to screen. It’s visual, it’s versatile, and it resets the stage every episode. Your characters step through the gate and they can be anywhere: a Norse mythology planet, an Egyptian civilization that survived off-world, a room full of replicating machines. The device is a clean narrative engine, and SG-1 ran it hard for a decade.

Second, and this matters more than people give it credit for, the show leaned into humor. Richard Dean Anderson’s Jack O’Neill… note the extra “l,” a small but deliberate change from Kurt Russell’s version in the film… was genuinely funny. The show was willing to be self-referential, to mock its own tropes, to let its characters acknowledge how absurd their situation was. There’s an episode in season ten, titled “200,” that is essentially a sustained piece of meta-commentary on ten years of making the show. That kind of confidence in its own identity kept SG-1 from feeling like it was just grinding through mythology.

Third, and most importantly for the franchise’s expansion: the world-building was designed to branch. The Goa’uld, the parasitic alien race who had been posing as Egyptian gods, of which the film’s villain Ra was one, weren’t just a plot obstacle. They were a mythology with room to grow. Greek gods, Norse gods, Arthurian legend… all of it got folded in over ten seasons, each new element adding texture without erasing what came before.

The Spinoff Problem (And How Stargate Mostly Solved It)

When Stargate Atlantis launched in 2004, it faced the challenge every spinoff faces: how do you create something that feels new without alienating the audience who already showed up?

The answer Atlantis landed on was geography. By moving the action to the Pegasus Galaxy… to the literal Lost City of Atlantis, abandoned ten thousand years earlier by the ancient race who built the Stargates… the show gave itself room to breathe. New galaxy, new enemies (the Wraith, a species that feeds on human life force), new team. It ran alongside SG-1 for several seasons before the original series ended, which meant the franchise was producing two concurrent shows at its peak. The two shared DNA: same creative team, same studios in Vancouver, some overlapping characters. But it felt distinct enough to justify both existing.

Atlantis ran five seasons and 100 episodes. It was canceled before its natural conclusion, with a planned direct-to-DVD film, Stargate: Extinction, ultimately shelved due to MGM’s financial difficulties. That ending, or lack of one, is one of the franchise’s genuine sore points.

Then came Stargate Universe, which premiered in 2009 and tried something different. Where SG-1 and Atlantis were fundamentally optimistic adventure shows with humor baked in, Universe went darker and more serialized. Its setup, a group of people stranded aboard an Ancient ship called Destiny, billions of light years from Earth with no obvious way home, had clear echoes of Battlestar Galactica, which was the prestige sci-fi drama of the moment. The tone was intentional; the show’s creators wanted to make something more psychologically complex, more willing to sit with its characters’ flaws and desperation.

The fan response was divided. Viewers who had loved the lighter tone of the earlier shows were, by some accounts, actively hostile to Universe. This is a frustration that co-creator Brad Wright later acknowledged contributed to the show’s declining ratings. Universe was canceled after two seasons, ending on a semi-cliffhanger that was eventually addressed through a comic book series. It’s the franchise’s most unresolved thread.

What Made It Work (And What Didn’t)

Looking at the full arc of the Stargate TV universe, a few patterns emerge.

The franchise worked best when it trusted its own premise. The Stargate device itself is endlessly flexible. It can go anywhere, which means the show can be anything in a given week. That flexibility is what let SG-1 sustain ten seasons without the storytelling calcifying. Some weeks were mythology-heavy; others were standalone adventures; others were comedic detours. The gate kept the formula from becoming a formula.

It also worked because the creative team stayed consistent. Brad Wright was involved across all three live-action series. Robert C. Cooper and Joseph Mallozzi had long tenures on SG-1 and Atlantis. That continuity of vision is rarer than it sounds in television, and it showed. The franchise had a coherent internal logic even as it expanded.

Where it struggled was in managing tone across entries. The shift from Atlantis to Universe was jarring enough that it fractured the audience rather than expanding it. There’s a version of Universe that might have worked as a companion piece to a franchise built on darker foundations; attached to one built on humor and adventure, it felt like a pivot the audience hadn’t consented to. That’s not a knock on the show’s ambition. It’s a structural problem that any long-running franchise eventually faces when it tries to evolve beyond its original identity.

The film sequels tell a similar story. Emmerich and Devlin spent years trying to develop their own continuation of the 1994 movie, one that would have ignored the television mythology entirely and picked up with Russell and Spader, and never got it made. As recently as 2016, those plans were described as stalled. The audience had moved on to what the TV shows had built, and the original creators found themselves locked out of their own premise.

The New Series and What It Has to Figure Out

The Amazon MGM series announced in November 2025 has real reasons for optimism. Martin Gero, who wrote for all three prior live-action series, is a known quantity within the franchise. Brad Wright and Joseph Mallozzi are returning in contributing producer roles. Roland Emmerich and Dean Devlin, the original film’s creators, are executive producers, which suggests a degree of creative reconciliation that has been a long time coming.

The stated goal is a show that honors the existing mythology while remaining accessible to new viewers. That’s a difficult needle to thread. The franchise’s most committed fans carry thirty years of lore; a casual viewer who never watched SG-1 needs to understand what a Stargate is and why it matters without sitting through a mythology lecture in episode one.

But the premise still works. An ancient ring-shaped device that opens wormholes across the universe is as good an idea in 2025 as it was in 1994. The question is whether the new series can do what the original TV era did at its best: use that device as an engine for something that feels alive, character-driven, and genuinely interested in the world it’s building.

The history of the franchise suggests it’s possible. It’s been done before, by people who didn’t have nearly the cultural moment that streaming science fiction currently enjoys.

That ring is still out there. Somebody just has to dial it right.
