Some sci-fi fans might hear Stargate and think only of the 1994 feature film starring Kurt Russell and James Spader. But others will be well aware that the film, about an archaeologist and an Air Force colonel tapped to explore a mysterious ring that’s actually a wormhole for interstellar travel, spawned an entire franchise. The TV series Stargate SG-1, which debuted in 1997 and ran for 10 seasons, plus two direct-to-video sequel movies, was hugely popular on its own, but viewers also got two additional spin-off series, an animated series, a web series, several different tie-in games, and multiple documentaries and specials. So it stands to reason that Amazon was well aware of Stargate having a built-in fan base when, last November, it greenlit a new series from writer, executive producer, and showrunner Martin Gero, who’d worked on Stargate: SG-1 as well as the spin-off Stargate: Atlantis.

At the time, Gero sounded understandably excited about the new series. “I’m beyond thrilled that Amazon MGM Studios has entrusted me with guiding this incredible franchise into its next phase,” he said in November 2025. “For those who’ve kept the gate active through conventions, rewatches, and unwavering faith—this one’s for you. And for those that are new to our world—I promise you’re in for something extraordinary.”
