| November 22, 2025 | By: Quinton O'Connor 5 comments so far This week fans of another “Star” franchise got big news about a long-awaited return to television. MGM and Amazon are bringing back Stargate , which should give fans of space-based sci-fi plenty of cause for celebration. Stargate’s absence from TV has Star Trek’s post-Enterprise hiatus beat, as it’s already been 14 years since the short-lived Stargate Universe went off the air on SyFy. The new television show will be a “new chapter” set in the same Stargate canon universe, and it apparently has been in development for over a year, but no release date has been yet set for the worldwide premiere on Prime Video. The upcoming Stargate series is a continuation in the franchise that started with the 1994 Stargate feature film, which presented the idea that all those Egyptian pyramids were the work of aliens and there were more spread around the galaxy, accessible via the eponymous “star gates.’ The Stargate SG-1 TV series came three years later, followed by Stargate Atlantis and Stargate Universe , along with a handful of TV movies. All in all, there are 17 seasons with 350 episodes, and like Trek, the franchise introduced a richly crafted world with a sprawling cast of heroes and villains whom audiences came to love and loathe. Along the way, quite a few familiar faces from the final frontier made their way through the gate. Star Trek alumni turned up in roles ranging from minor character to full-blown series regular—and perhaps some could be back. We could fill a book bigger than Daniel Jackson’s scholarly notes with every Star Trek actor that crossed over, so instead, we’ll focus on the ones we can actually see returning for the new series. These characters are still active in the Stargate canon, and if the writers want them back, we may indeed see their cross-fandom faces once more. Robert Picardo – Richard Woolsey Let’s get the big one out of the way right off the bat. Robert Picardo not only played The Doctor in Star Trek: Voyager for its seven-season run and reprised the character (via his voice) on Prodigy, but he’s gearing up for a highly anticipated homecoming by continuing the role in Star Trek: Starfleet Academy. Picardo also played a big part in SGverse, starting in Stargate SG-1 2004 as International Oversight Advisory representative Richard Woolsey. At first, Woolsey was a thorn in the protagonists’ side, but over time, they came to see him in a more heroic light. As a recurring character, Woolsey had several appearances on SG-1. More notably, he was ported over as the new head of the Atlantis Expedition in the fifth and final season of Stargate Atlantis, giving Picardo series regular status. Jolene Blalock – Ishta Despite her full-time status as T’Pol on Star Trek: Enterprise, Jolene Blalock found the time to swing by for a pair of Stargate SG-1 episodes involving Ishta, a rebel Jaffa who grew close with Teal’c (Christopher Judge) amid trying times for their newly freed people. Blalock appeared in just two episodes between the seventh and eighth seasons, but there’s nothing in the franchise’s later years to suggest that her budding relationship with Teal’c would have ended. Even if it did, her character is still out there, spearheading the construction of a new colony for her fellow female Jaffa. John Billingsley – Simon Coombs What if a sci-fi show’s proverbial camera tilted away from its protagonists and spent an episode through the eyes of the more ordinary sorts? TNG did it with “Lower Decks,” and then we got a whole animated series out of the premise. And, indeed, Stargate SG-1 had “The Other Guys.” The wacky season 6 episode gave fans scientists Simon Coombs and Jay Felger, who got in way over their heads but ultimately saved the day. John Billingsley, Enterprise’s delightful Phlox, played Coombs. Perhaps Simon Coombs could visit another alien world, getting into even more trouble in the process. Nicole de Boer – Alison Porter This one’s a long shot, but there’s nothing in-universe stopping it from happening. Star Trek: Deep Space Nine’s Nicole de Boer, who played newly joined Trill host Ezri Dax in season 7, made a single appearance in Stargate Atlantis in the horror-themed “Whispers.” Nicole de Boer brought that same sense of a hidden strength lurking behind a cloud of anxiety that made Ezri work so well to her guest role as Alison Porter, a scientist who fights alongside John Sheppard and the rest of SGA’s main squad. Funnily enough, the creatures they battle are monstrous creations of a Wraith villain named Michael, who was played by none other than Star Trek: Enterprise’s Connor Trinneer… Connor Trinneer – Lastlight/Michael Kenmore/Paul Langford …who is next on our list! Connor Trinneer is, of course, Trip Tucker in Star Trek: Enterprise. But he had a nice-sized role as Lastlight, or as John Sheppard loved to call him, “Michael,” from the second through the fifth season of Stargate Atlantis. Toward the end of that series, Michael’s darker ambitions finally caught up with him and he met his end. But Stargate, like Star Trek, often revels in alternate-timeline shenanigans. Michael could serve up an encore performance as the nefarious hybrid, or we could even see Trinneer reprise his Stargate Origins role as mid-2oth-century swashbuckling archaeologist Paul Langford. (We’d like to see Trip come back to life, too.) Armin Shimerman – Anteaus Another long shot, DS9’s very own Quark swung by very early in SG-1’s run as Antaeus, one of the ruling members of the ancient race of beings known as the Nox. Armin Shimerman ably demonstrated his appreciable range here; Antaeus is nothing like Quark whatsoever. Peaceful and kind, Antaeus would never be seen at the dabo table. Given the importance of the Nox as one of the four original advanced races in the Milky Way and the fact that none of the Stargate shows ever did pretty much anything with them after season 1, it’s not unfathomable that Shimerman might have more wisdom to impart upon a new generation of galactic explorers. Marina Sirtis – Svetlana Markov Marina Sirtis has brought TNG’s Counselor Deanna Troi to so many episodes of Star Trek that her solo gig in season 4 of Stargate SG-1 is a veritable blip on her submarine’s radar by comparison. Svetlana Markov was the scientific mastermind behind Russia’s secret Stargate program, and she led our heroes to an underwater investigation as to what wicked fate befell their version of Stargate Command. If Stargate’s future carries forward Russia’s key role in intergalactic affairs—now that’s a sentence we’d never type for Star Trek!—the writers could bring in a familiar face with Markov. Ronny Cox – Robert Kinsey The Stargate franchise left more than a few doors open in its waning years, with several unresolved plot points. The fate of Robert Kinsey, a scheming politician who was seen in ten episodes of Stargate SG-1 across its first eight seasons, is one of them. The writers clearly left the door open for Ronny Cox’s villain to have survived an explosion that would otherwise have killed him. Cox, who played the pugnacious Admiral Edward Jellico in the Star Trek: The Next Generation two-parter “Chain of Command” and returned in eight episodes of Star Trek: Prodigy, could always come back for one last ride. Honorable mentions and future possibilities Several further Star Trek stars made a noteworthy impact on Stargate before their characters were unceremoniously killed off. DS9’s Colm Meaney was Cowen, leader of the Atlantis Expedition’s Pegasus Galaxy rivals, the Genii. Much like O’Brien, he was even a chief! John de Lancie (aka Q) took a truly human form as the sociopathic NID agent Frank Simmons. And Dwight Schultz, who played Reginald Barclay on The Next Generation and Voyager, brought his vibrant presence to the SG-1 episode “The Game.” And sadly there are a few Star Trek actors who stepped through the gate into the great beyond, like DS9’s René Auberjonois. Simply put, Star Trek’s casting stream crossed with Stargate’s dozens upon dozens of times, so don’t be surprised if you see a few Alpha Quadrant denizens in the currently untitled Stargate revival. We could even see actors exclusive to Trek’s modern era. Who wouldn’t enjoy watching Jack O’Neill crack a joke about Anson Mount’s luxurious hair? But wait… there’s more! How about a reversal? Paul McGillion had a quick scene with just a few sentences’ worth of dialogue in the 2009 Star Trek movie, but much has been made over Stargate Atlantis‘ beloved Dr. Carson Beckett making the leap between franchises from a Starfleet Academy barracks leader to the Atlantis Expedition’s kindhearted and pacifistic leading physician. McGillion was credited as a series regular for SGA‘s first three seasons; he returned in the season 4 finale and then five more times in the show’s fifth and final season. Suffice it to say, he’s a big deal, and there’s ample reason for the writers to bring him back. There’s also Louis Ferreira, who appeared in one episode of Star Trek: Voyager (credited as Justin Louis) as Trevis, a friendly wooden fellow in young Naomi Wildman’s holodeck fairy tale. Ferreira is better known for his role as Colonel Everett Young on Stargate Universe. Given that SGU ended on a cliffhanger, the Destiny is presumably still out there, its crew in stasis, its mission unfinished. And much like Svetlana Markov, Tamlyn Tomita’s Shen Xiaoyi offered a window into another nation’s involvement with the Stargate. The IOA’s Chinese representative appeared in multiple episodes of both SG-1 and Atlantis. Viewers of season 1 of Star Trek: Picard will recognize Tomita as the duplicitous Starfleet Commodore Oh. We’re not sure where Oh ran off to, but if Xiaoyi is still a part of the IOA, she should be easy enough to find.

We wish our fellow galaxy-trotting TV fans nothing but the best as another peak sci-fi franchise embarks on the next chapter of its historic journey.
