    Denise Crosby on Auditioning for TNG: How Macha Hernandez Became Tasha Yar

    Before she was Tasha Yar, she was Lieutenant Commander Macha Hernandez. For the Season 14 finale of The Trek Files, Denise Crosby joins Larry Nemecek to revisit her original 1987 audition sides for Star Trek: The Next Generation, including early character descriptions that reveal a very different version of the Enterprise's security chief. Denise first read for Deanna Troi before Gene Roddenberry made a pivotal switch, reshaping the role of Macha Hernandez into Tasha Yar to fit Denise's strengths. In this week's episode, Denise reflects on the audition process, her favorite scene between Troi and Yar that was never filmed, and what those early creative decisions revealed about the direction of TNG. She also shares memories of those uncertain early days of production, the risk of launching a syndicated sequel to an iconic series, and the emotional complexity of stepping into (and eventually stepping away from) such a historic role. Along the way, Denise speaks movingly about loss after the Palisades fire, resilience, fandom, and what it means to revisit Star Trek decades later. It's a revealing look at how a character evolves, how casting can reshape canon, and how even discarded script pages tell the story of Star Trek's creative DNA.

  2. Star Trek IV's Lost Saavik Scene with Robin Curtis

    Star Trek IV's Lost Saavik Scene with Robin Curtis

    In this very special episode of The Trek Files, actor Robin Curtis joins us to revisit a little-known chapter in Saavik's story, one that never made it to screen. Drawing from a pair of early Star Trek IV: The Voyage Home script drafts, we explore a scene that implies Saavik is pregnant with Spock's child, a narrative thread begun in Star Trek III but quietly dropped by the time the final film was released. Robin shares warm memories of working with Leonard Nimoy, the late Harve Bennett, and her fellow castmates, as well as a few eye-opening truths about the unpredictability of Hollywood. Plus, she discusses her return to the role of Saavik in OTOY's Unification, and we recreate the pivotal, never-filmed scene between Kirk and Saavik. It's an emotional, candid, and deeply human conversation about legacy, missed opportunities, and what it means to carry a character with you for decades. Documents and additional references: First Draft (August 23, 1985): Conversation between Kirk and Saavik revealing her pregnancy by Spock. Second Draft (November 18, 1985): Subtle reference via McCoy's line: "I'm a surgeon, not a pediatrician."

  3. How 'The Chase' Inspired Star Trek: Discovery's Final Season

    How 'The Chase' Inspired Star Trek: Discovery's Final Season

    Before Star Trek: Discovery's final season sent its crew in pursuit of ancient secrets, Carlos Cisco had already taken inspiration from one of the most profound episodes of The Next Generation, "The Chase." In this week's The Trek Files, Carlos returns to explore the thematic connections between the 1993 TNG episode and Discovery's modern narrative arc. With Larry Nemecek, he discusses how "The Chase" influenced the creation of the alien species Progenitors and how its ideas about shared ancestry and unity resonated with the story of L'ak and the Breen in Discovery Season 5. Document and additional references: Star Trek: The Next Generation episode "The Chase," final draft script (revised Feb 4–10, 1993) Written by Ronald D. Moore & Joe Menosky, directed by Jonathan Frakes.

    Questor Rebooted

    This week, we're joined once again by Cash Edwards, who shares an intimate look at his longtime friendship with Star Trek: The Next Generation producer Herbert J. Wright. Their relationship, and shared history with Gene and Majel Roddenberry, sparked a bold attempt to revive one of Gene's most personal concepts: The Questor Tapes. In 2004, Herb, Cash, Rod Roddenberry, and a team that included Mike Okuda and Jules Urbach put together a new pitch for Questor—a project updated for the post-9/11 world but still driven by the timeless Roddenberry themes of evolution, ethics, and survival. From detailed series bibles to pilot treatments and fan outreach, Cash walks us through the chaotic early years of TNG, the roots of Questor, and the bittersweet story behind its final pitch.

  5. How Star Trek: The Next Generation Built a Believable Warp Drive

    JAN 20

    How Star Trek: The Next Generation Built a Believable Warp Drive

    This week on The Trek Files: warp coils, dilithium chambers, and a whole lot of gamma rays. Returning guest Rick Sternbach joins Larry Nemecek once again for a lively exploration of Star Trek: The Next Generation's scientific backbone. Using early technical memos and a classic 1987 warp engine sketch, Rick walks us through how the team brought real-world physics into the heart of the Enterprise-D's design and when they just had to make it up. From working with Los Alamos physicists to devising the ejection system for the warp core, Rick shares stories of how he and Mike Okuda grounded the show's tech in reality while still serving the drama. Ever wonder why deuterium goes on top, antimatter on the bottom, or how a photon torpedo really works? This one's for the technobabble lovers and science fans alike.

  6. The Book That Launched a Franchise Revival

    The Book That Launched a Franchise Revival

    Long before The Next Generation brought LCARS to life or 3D printers made cosplay easier, Star Trek fans relied on one book to make the Enterprise feel real: The Starfleet Technical Manual by Franz Joseph. In this week's episode, Larry Nemecek welcomes back Karen Schnaubelt, daughter of Franz Joseph, to mark the 50th anniversary of that seminal 1975 publication, just weeks after its surprise appearance atop the New York Times bestseller list. More than just a how-to guide for warp drives and turbo lifts, the Tech Manual became a cornerstone of Trek fandom and helped lay the foundation for the Star Trek revival that followed. Karen reflects on her father's unique journey from retired engineer to pop culture icon, how the Technical Manual grew out of lunch-hour sketches and club meetings, and what it was like watching fandom embrace a book that treated Star Trek like a living universe. Plus, Larry and Karen discuss how that very success may have stirred some tension in Gene Roddenberry's orbit.

    Exploring Gene Roddenberry's Star Trek: The Motion Picture Novel Preface

    Writer/producer Mike Sussman returns to The Trek Files with a personal favorite: the creative and very meta preface to Gene Roddenberry's novelization of Star Trek: The Motion Picture. In it, Gene (writing as himself and as Admiral Kirk) casts the original Star Trek series as a fictionalized dramatization of real events. Wait… what? Join Mike and Larry Nemecek as they unpack Roddenberry's playful (and possibly defensive) retcon of Trek canon, written at a time when Gene was emerging as a sci-fi thought leader in the post-Star Wars, post-lecture-circuit era. It's Roddenberry as revisionist historian, spinning group consciousness, mind control revolts, and alternate human evolution… all in the introduction to his own movie tie-in novel. You may never look at the "real" Kirk, or Trek canon, the same way again.

  8. How Star Trek TNG's Tech Stayed (Almost) Scientifically Accurate

    How Star Trek TNG's Tech Stayed (Almost) Scientifically Accurate

    What happens when your sci-fi franchise is also a part-time science think tank? This week, Rick Sternbach returns to The Trek Files to discuss a set of internal memos he and Michael Okuda sent to the TNG production team, an essential peek behind the curtain at how plausible science and week-to-week TV production collided during the Berman era. These "tech notes" weren't just background noise. They helped shape the direction of key episodes, lent credibility to futuristic concepts like nanotechnology and AI, and quietly preserved Trek's internal logic. From computer core comparisons to white dwarf fragments, Rick walks us through how the art department helped make the 24th century feel real and even got a line read by Scotty. Whether you're a longtime fan of the TNG Technical Manual or just someone who geeks out over starship systems, this one's for you. Documents and Additional References: Technical Memo: "Evolution" – notes on nanotechnology, AI behavior, and micro-replication systems in TNG S3E1 Technical Memo: "Hollow Pursuits" – science commentary and plausible extrapolations for the episode's holodeck failure storyline Technical Memo: "The Most Toys" – suggestions on transporter physics and energy beam effects Naren Shankar (science advisor and writer, TNG Seasons 3–7) Joan Pearce (continuity consultant, Roddenberry-era Star Trek) The Trek Files Season 14 on Memory Alpha All episodes and documents: The Trek Files on Memory Alpha Visit the Trekland site for behind-the-scenes access and exclusive merchandise.
