Star Trek has always thrived on its legacy and making use of its huge extended lore. Despite new eras and new crews and bold new storytelling, it’s often the cameos from cast and crew of series past that get fans the most excited. From McCoy reminiscing to Data in The Next Generation, to Sulu making an appearance in Voyager, bringing back fan favourites not only brings a quick win with the nostalgia factor but is often a great way to make connections between shows and create continuity within the Trek universe as well as an opportunity to tie up loose ends and explore what our favourite officers are up to these days. But unfortunately for us, what could have been one of the biggest cameo moments Star Trek has ever seen, sadly, never came to fruition.

Long before Strange New Worlds began to reignite fans’ interest in The Original Series, Enterprise nearly pulled off the crossover of a lifetime. In an interview with TrekMovie.com, Enterprise writer and producer Mike Sussman, explained how showrunner Manny Coto envisioned a two-part Mirror Universe story for the show’s fourth season that would feature Shatner as the centrepiece, saying “There was a long discussion [about] getting Bill Shatner on the show —we were trying [for months] to make it happen, but ultimately the network or the studio wouldn’t meet his quote.”
A Mirror Universe Kirk?
The year was 2004, a full decade after Kirk’s tragic on-screen death in Star Trek: Generations, and Enterprise showrunner Manny Coto was looking for a way to breathe new life into a struggling show. His idea? An epic Mirror Universe story that would reintroduce the legendary William Shatner as the darker counterpart to the Federation’s most iconic captain.
The concept — developed with longtime Star Trek novelists Judith and Garfield Reeves-Stevens who wrote a series of novels with Shatner including Star Trek: Spectre — would have followed ‘Emperor Tiberius’, the Mirror Universe version of Kirk first seen in the novel. The story would’ve seen him stranded in the past, forced to team up with Captain Jonathan Archer (Scott Bakula) and the NX-01 crew in an uneasy alliance, the two leaders reluctantly working together. The story would have served as both a sequel and prequel to the Mirror Universe — revealing how the Terran Empire came to be.
The plan was certainly bold and fittingly theatrical, pretty damn perfect for Shatner, whose performances as Kirk have always been just that tad bit over the top… It’s easy to imagine Shatner fully going for it with this role — his signature mix of charisma and melodrama turning into a scene-stealing performance as Emperor Tiberius. We imagine it would have been a cameo of epic proportions. Seeing Shatner go the full hog, hamming it up and embracing the swagger that made his Kirk so iconic, while exploring a darker version of the character, could’ve turned a simple guest appearance into one of the most memorable episodes in Star Trek history. It might’ve been just the kind of nostalgia Enterprise needed to survive another season.
Unfortunately, the plan never came together. Paramount actually conducted focus group testing to gauge fan reaction to Shatner’s potential return, according to TrekMovie.com, even preparing a promo reel titled “A Legend Returns to Star Trek,” using footage of Kirk from The Wrath of Khan. In the end, budget and timing issues halted the project before it could materialize. Shatner was starring in ABC’s Boston Legal at the time and despite strong fan interest, sadly, by the time negotiations got serious for his return to Trek, Enterprises’ fate was already sealed, and it’s likely UPN wasn’t willing to meet Shatner’s quote as they weren’t certain his appearance would be enough to generate new interest in the show, which was already on the decline with falling ratings.
What the Mirror Episode Became
The deal with Shatner might have fallen through, but Enterprise still got its Mirror Universe story. Writer and producer Mike Sussman repurposed elements of his earlier idea into what became “In a Mirror, Darkly,” a fan-favorite two-parter that showed us the NX-01 crew’s ruthless counterparts in the ‘Terran Empire’. Rather than featuring Kirk or the Federation, the episode more fully explored the Mirror Universe, chronicling how The Mirror crew discovers the USS Defiant — a lost Constitution-class starship from The Original Series episode “The Tholian Web”— and uses its advanced 23rd-century technology to accelerate their conquest of space. The story was an instant hit with fans, combining retro set design and fan-service Easter eggs. It was a pure love letter to TOS and 1960s visuals.
Still, it’s hard not to wonder what might have been. Seeing Shatner, back on the bridge, playing one of Sci-Fi’s most enduring heroes, turned on his head as a power-hungry, evil version of Kirk would’ve added a fascinating new layer to Mirror Universe lore, bridging the gap between TOS and Enterprise’s era, while giving Shatner the kind of dramatic role he excels in. Imagine Shatner’s Tiberius butting heads with Bakula’s evil Archer. It would’ve been classic Star Trek — the perfect mix of campiness, gravitas, and humor.
Ultimately, “In a Mirror, Darkly,” became a favorite in its own right. Still, Shatner’s mirror episode that never was is a tantalizing “what if”. The fact that Shatner was genuinely interested — with his Boston Legal schedule reportedly able to accommodate the appearance — makes the loss sting even more. As Judith and Garfield Reeves-Stevens later recalled in the Roddenberry Archive mini-doc The Further Adventures of James T. Kirk, according to TrekMovie.com: “He just loved the idea of playing Tiberius.” It was a chance for Shatner to revisit his legacy while also having a little fun with it.
While Shatner’s return might not have saved Enterprise from cancellation, it would have given the prequel series the kind of crossover moment fans still talk about today and been a hell of a high for the show to end on. Two decades later, other attempts to bring back Captain Kirk have sparked debate among fans. While modern Star Trek projects like JJ Abrams reboot trilogy and Strange New Worlds have shown new ways to revisit legacy characters, Shatner’s unmade Enterprise return wasn’t just about bringing Kirk back — it was about exploring who he might’ve become in another universe and knowing Shatner, it would’ve been anything but subtle.
Would William Shatner’s return as Emperor Tiberius have changed Enterprise’s fate? Let us know in the comments and keep the conversation going in the ComicBook Forum.
