Antoinette Bower, a German-born British performer who captivated science fiction audiences with memorable roles on both “Star Trek” and “The Twilight Zone,” died April 30, 2026, at an assisted living facility in Eagle Rock, Los Angeles, at 93. Her friend Carlotta Glackin confirmed the death, which was not publicly reported until July 11.
No cause of death was disclosed. Glackin, a great-niece of Golden Age character actor Edward Everett Horton, revealed that Bower continued to receive fan letters from devoted “Star Trek” enthusiasts decades beyond her sole appearance on that show. Actor William Shatner, her co-star in that episode, sent condolences upon hearing of her passing, Glackin noted.
Early Life and Humanitarian Service
Born Antoinette Alexandra Jane Bower on September 30, 1932, in Baden-Baden, Germany, to an English father and a German mother, she received her education in England. During the late 1940s, she worked in language supervision and welfare counseling positions for the United Nations’ International Refugee Organization (IRO), which aided millions of displaced persons across Europe and Asia following World War II.
In 1953, Bower joined her family in Canada and found work with the nascent Canadian Broadcasting Corporation (CBC) in Toronto, where she handled public affairs assignments, wrote scripts and hosted live television interviews. Her acting career began during this period, with appearances in a 1958 television version of “The Tell-Tale Heart” and on the syndicated program “Hudson’s Bay” in 1959.
A trip to Los Angeles led to her decision to remain in California after landing an uncredited part in Marlon Brando’s “Mutiny on the Bounty” in 1962. The move launched a nearly four-decade career that established her as one of television’s most sought-after guest performers.
Iconic Science Fiction Performances
In “Probe 7, Over and Out,” a November 1963 episode from “The Twilight Zone” fifth and final season, Bower played Eve Norda, a woman marooned on a far-off planet alongside astronaut Adam Cook, portrayed by Richard Basehart. Rod Serling wrote the installment, which Ted Post directed.
Her most celebrated genre role came in October 1967 when she starred as the malevolent Sylvia in the second-season “Star Trek” episode “Catspaw,” appearing opposite Theo Marcuse’s Korob. The character initially presented as an alluring human woman before revealing her true form as a giant feline alien. That single performance secured Bower’s status among the series’ most unforgettable guest stars.
Extensive Television and Film Work
Throughout her career, Bower amassed an impressive roster of television appearances. Her credits included “Perry Mason,” “Alfred Hitchcock Presents,” “Wagon Train,” “The Man From U.N.C.L.E.,” “The Fugitive,” “Bonanza,” “Hawaii Five-O,” “Get Smart,” “Hogan’s Heroes,” “Mission: Impossible,” “Columbo,” “Kojak” and “Murder, She Wrote.” She also had a role in the 1983 miniseries “The Thorn Birds.”
Her film work included top billing as Dr. Alix Pardee in the 1972 horror picture “Superbeast.” She portrayed the wife of Leslie Nielsen and mother of Jamie Lee Curtis in the 1980 slasher film “Prom Night,” playing a character haunted by her younger daughter’s accidental death. Charles Bronson kidnapped her character in the 1984 action thriller “The Evil That Men Do.”
From 1989 through 1992, Bower held a recurring part on the Canadian drama “Neon Rider” as Fox Devlin, a colleague of Dr. Michael Terry, played by Winston Rekert. The show was set on a British Columbia ranch for troubled and abused teenagers.
Creative Pursuits After Acting
Following her departure from “Neon Rider,” Bower left acting but maintained her creative energy through diverse projects. She created a documentary about Canadian chuckwagon racing, personally managing the cinematography, direction, editing and narration. She pursued carpentry studies at Santa Monica College, built custom cabinets and tall bookshelves, and became a valued Home Depot employee.
In 1963, Bower married American pop artist James Gill; the marriage ended in divorce. Her half-brother, Roger, predeceased her. A celebration of life is planned for September 26 in Pasadena to honor an actress whose performances continued attracting fans long after she exited the industry.
