Star Trek: Starfleet Academy assembled one of the most accomplished casts in modern Star Trek history — a group that included an Academy Award winner, an Emmy-winning character actor, a veteran of the British stage, and a professional dancer who had never acted before. The casting was deliberately bold: where previous Trek series had built their ensembles around genre veterans and character actors, Starfleet Academy went after marquee talent and fresh faces in equal measure. The result was a cast that elevated material that could have been merely competent into something genuinely surprising — and a behind-the-scenes dynamic that, by all accounts, was one of the warmest in Trek production history.
Holly Hunter as Captain Nahla Ake — Chancellor of Starfleet Academy and captain of the USS Athena. Born March 20, 1958, in Conyers, Georgia. Hunter won the Academy Award for Best Actress for The Piano (1993), directed by Jane Campion, and received three additional Oscar nominations for Broadcast News (1987), The Firm (1993), and Thirteen (2003). She won an Emmy Award for The Positively True Adventures of the Alleged Texas Cheerleader-Murdering Mom (1993) and another for Saving Grace (2009–2010). She is also known for voicing Helen Parr in Pixar's The Incredibles (2004, 2018) and for Raising Arizona (1987), O Brother, Where Art Thou? (2000), and Batman v Superman: Dawn of Justice (2016) [1][2].
Hunter was 67 at the time of Starfleet Academy's premiere — making her one of the oldest leads in Star Trek history. Her casting was a statement of intent: this was not a show about young twentysomethings finding themselves, but about an institution led by someone who had seen centuries of history. Alex Kurtzman described the initial pitch: "I'm thinking barefoot — what do you think?" Hunter embraced the idea. Her Captain Ake is barefoot throughout the series, moving with a fluid physicality that Hunter developed with the showrunners. The character's name, Nahla, means "water in the desert" — a quality Hunter brought to the role through her physical performance [1][3].
Hunter wrote Trek technobabble lines on her bedroom ceiling to memorize them — a technique she had used in previous roles. She described working with Paul Giamatti as a creative challenge: "I wanted to be at the top of my freaking game with Giamatti because he made me be, because he was. He's like one of the greatest actors that I've ever worked with" [3].
Sandro Rosta as Caleb Mir — A human cadet raised on the run since age six, recruited by Ake to find his missing mother. Born in London, England, to a British-Canadian family. Rosta trained at the Oxford School of Drama and had virtually no screen credits before Starfleet Academy. He was cast mere days before production began — the last piece of the ensemble puzzle [4][5].
Rosta's Caleb is the show's emotional center — a young man who distrusts institutions, resents the woman who separated him from his mother, and must decide whether the Academy is worth believing in. His arc across the season mirrors the show's larger question: whether institutions built on idealism can survive the compromises required to sustain them. Rosta's performance was praised by critics for its rawness and naturalism — qualities that felt authentic to a character who had never lived inside a system [4].
Karim Diané as Jay-Den Kraag — A Klingon cadet training in life sciences and medicine. Diané's Jay-Den is the first full-blooded Klingon main character since Michael Dorn's Worf — and the first openly gay Klingon in Trek history. The character's arc across the season explored what it means to be Klingon in a galaxy where the Klingon Empire was destroyed during the Burn, leaving Klingons an endangered species [5][6].
Diané's Klingon prosthetics initially took five hours to apply each morning — reduced to two hours by season's end as the makeup team refined the process. Before his first day in prosthetics, Diané FaceTimed Michael Dorn for advice. Dorn told him about the physical toll of long hours in Klingon makeup and warned him about the intensity of passionate Klingon fans. Mid-season, Diané also called Doug Jones (Saru from Discovery) for additional prosthetic advice [6].
Kerrice Brooks as SAM (Series Acclimation Mil) — A Kasqian (holographic species) cadet, only weeks old but programmed as a young adult. Born April 6, 2000, in Washington, D.C. Brooks was a professional dancer before transitioning to acting, appearing in the 2024 film My Old Ass [4][7].
SAM was originally written as a very different character. After Brooks auditioned, Kurtzman and Landau called each other simultaneously. As Kurtzman later recounted: "We are in the presence of a genius. We actually need to rewrite the character for her." The character was rebuilt from the ground up to match Brooks's energy and performance style — a rare instance of an actor reshaping a role through sheer talent [7].
SAM became the show's most narratively significant character — the investigator of Sisko's fate in the DS9 tribute episode, and the holographic daughter of the Doctor in "The Life of the Stars." Brooks described working with Cirroc Lofton as transformative: "It really felt like he held my head above the water, like in the scene in Moonlight, when he's teaching the young boy how to swim" [7].
George Hawkins as Darem Reymi — A Khionian cadet from a wealthy homeworld who is secretly a prince. Hawkins brought a restrained physicality to Reymi — a character whose privilege is both his greatest asset and his most significant barrier to genuine connection with his fellow cadets [4].
Bella Shepard as Genesis Lythe — A Dar-Sha cadet (a new species created for the show) and daughter of an admiral, training on the command track. Shepard's Lythe is the cadet who most embodies the Academy's institutional values — and the one most tested when those values collide with reality [4].
Zoë Steiner as Tarima Sadal — The telepathic daughter of the President of Betazed, who enrolls in the War College rather than the diplomatic track. Steiner's Tarima is a love interest for Caleb, but the character's telepathy adds a layer of complexity: she can sense what others feel, making genuine emotional connection both easier and more fraught [4].
Oded Fehr as Admiral Charles Vance — Reprising his role from Star Trek: Discovery, where Vance served as Commander-in-Chief of Starfleet throughout the 32nd-century seasons. Fehr's Vance is the show's link to the broader political landscape — the man who must balance idealism with the brutal pragmatism of post-Burn governance [1][5].
Gina Yashere as Commander Lura Thok — A half-Klingon, half-Jem'Hadar Cadet Master and first officer of the USS Athena. Born November 6, 1974, in London, England. Yashere is a stand-up comedian and television personality, known for her appearances on The Daily Show and her own Netflix special Tall, Dark, and Caucasian (2018). Her casting as a half-Klingon, half-Jem'Hadar officer — two species that were mortal enemies in DS9 — was a character concept that embodied the show's theme of unlikely alliances [1][5].
Yashere became the show's most visible public defender during the review-bombing campaign. Her viral Instagram response to Elon Musk — "All this from a guy who has all the money in the world, yet his face still looks like a sock full of wet sand" — became one of the most talked-about moments surrounding the series [8].
Robert Picardo as The Doctor — The Emergency Medical Hologram from Star Trek: Voyager, now over 800 years old. Picardo originated the role in Voyager (1995–2001) and has reprised it in Star Trek: First Contact (1996), Star Trek: Prodigy (2022–2024), and now Starfleet Academy. His career spans decades, with notable roles in The Wonder Years, China Beach, The Howling (1981), and Dickinson [9].
The Doctor's arc in Starfleet Academy — culminating in "The Life of the Stars," where he raises SAM as his daughter on Kasq for seventeen years — gave Voyager's most beloved character the emotional resolution the original series never provided. Picardo's performance as a father learning to love after 800 years of avoidance was widely praised as the season's finest work [9].
Tig Notaro as Commander Jett Reno — Reprising her role from Star Trek: Discovery, where Reno served as the ship's chief engineer. Notaro, a stand-up comedian and actress known for One Mississippi (2015–2017) and Star Trek: Discovery (2018–2022), brought her signature deadpan delivery to the Academy's physics and engineering instruction. Her presence on the show became a flashpoint in the review-bombing campaign, with Fox News specifically targeting Notaro — who is openly lesbian — in segments criticizing the show's diversity [1][10].
Brit Marling as USS Athena Computer Voice — The voice of the ship's computer, a role that required Marling to deliver technobabble with warmth and personality. Marling is known for creating and starring in The OA (2016–2019) and for roles in Another Earth (2011) and Sound of My Voice (2011) [1].
Stephen Colbert as Digital Dean of Students — A voice-only role as the Academy's daily announcement system. Colbert, the host of The Late Show and a lifelong Star Trek fan, brought a playful authority to the part [1].
Paul Giamatti as Nus Braka — A half-Klingon, half-Tellarite pirate and the season's principal antagonist. Born June 6, 1967, in New Haven, Connecticut. Giamatti received an Academy Award nomination for Cinderella Man (2005) and won the Emmy Award for Outstanding Lead Actor in a Miniseries or Movie for HBO's John Adams (2008). He is known for Sideways (2004), Billions (2016–2023), The Holdovers (2023), and Downton Abbey (2019) [11].
Giamatti's casting was the result of a remarkable act of manifestation. During press for The Holdovers in 2023, he told a journalist that his dream role was "a Klingon on Star Trek." The showrunners found out and offered him roles within 24 hours via Zoom. Giamatti called Michael Dorn and Doug Jones for prosthetic advice before beginning [11].
Giamatti's performance was deliberately big — he told the showrunners early on: "I'm playing this combination of two incredibly aggressive alien species. You okay if I really go for the aggression?" They agreed. He described the experience: "Most of it felt in danger of going off the edge of a cliff, but I don't think I did" [11].
Tatiana Maslany as Anisha Mir — Caleb's missing mother, whose fate drives the season's central narrative. Born September 22, 1985, in Regina, Saskatchewan. Maslany won the Emmy Award for Outstanding Lead Actress in a Drama Series for Orphan Black (2013–2017), in which she played eleven distinct clones [1].
Cirroc Lofton as Jake Sisko — See the Milestones blurb for the full story of Lofton's return as Benjamin Sisko's son, making his first live-action appearance in the role since the DS9 finale in 1999 [6][7].
Tawny Newsome as Professor Illa Dax — The latest host of the Dax symbiont and a professor at the Academy. Newsome, known for Brooklyn Nine-Nine and Space Force, also co-wrote "Series Acclimation Mil" with Kirsten Beyer [6].
Gaia Violo — Creator of Starfleet Academy. Violo developed the series from a concept that had been gestating in various forms since the mid-1980s. The original 1986 concept by Sam and Gregory Strangis — a "Starfleet Academy on a ship" — had been envisioned for what became The Next Generation before being shelved. Violo's version, developed for the modern era, retained the core idea while updating it for a 32nd-century setting and a YA demographic [1][4].
Alex Kurtzman — Showrunner and executive producer. Kurtzman signed a five-year deal with CBS in June 2018 to expand the Star Trek franchise, and Starfleet Academy was part of that original plan. He directed the premiere two episodes and co-wrote the season finale. Kurtzman's Trek tenure has been divisive — praised for expanding the franchise's reach but criticized by some fans for what they see as an over-emphasis on action at the expense of philosophy [1][4].
Noga Landau — Co-showrunner with Kurtzman. Landau brought a YA sensibility to the series, having previously worked on Nancy Drew (2019–2023). Her influence was visible in the show's emphasis on younger characters, emotional accessibility, and serialized storytelling [1][4].
Kirsten Beyer — Writer and producer who co-wrote the DS9 tribute episode and the season finale. Beyer had been a key writer on Star Trek: Discovery and Star Trek: Picard, and her deep knowledge of Trek lore made her the natural choice for the show's most continuity-heavy episodes [6].
Jonathan Frakes — Directed episode 9, "300th Night," which he described as his final Trek directing job for the foreseeable future. Frakes — who has directed more Trek episodes than almost anyone, including two TNG films — praised the show's sets: "It was literally the biggest Star Trek set ever" [10].
