While best known for Star Trek, Shatner's sci-fi credentials extend to several iconic series.
On September 7, 2026, TVLine highlighted five significant science fiction television shows featuring William Shatner, emphasizing that his contributions to the genre extend far beyond his iconic role as Captain James T. Kirk in Star Trek. This report comes amidst reflections on Shatner's diverse career as both a legendary actor and cultural icon.
Among the notable sci-fi series Shatner appeared in is the classic anthology series, The Twilight Zone. His involvement in this series featured two memorable episodes prior to his Star Trek fame. In the Season 2 episode, "Nick of Time," Shatner portrayed a character fascinated by a fortune-telling machine, showcasing his early acting prowess. Three years later, he starred in the acclaimed Season 5 episode "Nightmare at 20,000 Feet," where he delivered an unforgettable performance as a man imagining a creature lurking on the wing of his airplane. These pivotal roles helped establish Shatner as a compelling figure in sci-fi storytelling.
Shatner’s career also saw him venture into another anthology series, The Outer Limits. In this show, inspired by The Twilight Zone, he appeared in the Season 2 episode titled "Cold Hands, Warm Heart." This episode explored the unsettling experiences of astronaut Jeff Barton, who encounters troubling changes upon his return from space travel—a role that further cemented Shatner’s place in the sci-fi genre.
A shift in tone came with Shatner's recurring role in the NBC sitcom 3rd Rock From the Sun. Premiering in 1996, this show featured a group of extraterrestrials living on Earth disguised as a normal American family. Shatner’s character, known as The Big Giant Head, hilariously led the aliens through various adventures during his five-episode guest appearance in Seasons 4 and 5. This role allowed Shatner to showcase his comedic talents while contributing to a distinctly different flavor of science fiction.
Shatner ventured back into science fiction in animation with a guest appearance in Futurama. In the Season 4 episode, "Where No Fan Has Gone Before," he appears as himself alongside several cast members from the original Star Trek. This episode cleverly satirizes the franchise’s legacy and pays homage to Shatner’s immense influence within the sci-fi community. Shatner's cameo is a testament to his enduring popularity and connection with fans of the genre.
In addition to his numerous guest roles, Shatner also created and starred in his own sci-fi series, TekWar, in the 1990s. Based on a novel series of the same name, TekWar tells the story of a former police officer navigating a dystopian future marked by an illicit drug. Although the series was only on air for two seasons and garnered mixed reviews, it highlighted Shatner's multifaceted involvement in the science fiction narrative landscape.
William Shatner’s contributions to science fiction extend far beyond his legendary portrayal of Captain Kirk. With memorable performances in acclaimed anthologies, innovative comedy, and even a self-created series, Shatner has left an indelible mark on the genre. His diverse roles illustrate not merely a deep affection for science fiction but also an ongoing relationship with audiences that transcends individual projects. This appreciation is likely to resonate with both long-time fans and newer viewers discovering his work.
