X-Minus One

X Minus One is an American half-hour science fiction radio drama series that was broadcast from April 24, 1955, to January 9, 1958, in various timeslots on NBC. Known for high production values in adapting stories from the leading American authors of the era, X Minus One has been described as one of the finest offerings of American radio drama and one of the best science fiction series in any medium.

Initially a revival of NBC’s Dimension X (1950–51), the first 15 episodes of X Minus One were new versions of Dimension X episodes, but the remainder were adaptations by NBC staff writers, including Ernest Kinoy and George Lefferts, of newly published science fiction stories by leading writers in the field, including Isaac Asimov, Ray Bradbury, Philip K. Dick, Robert A. Heinlein, Frederik Pohl, and Theodore Sturgeon, along with some original scripts by Kinoy and Lefferts.

Included in the series were adaptations of Robert Sheckley’s “Skulking Permit”, Bradbury’s “Mars Is Heaven”, Heinlein’s “Universe” and “The Green Hills of Earth”, Pohl’s “The Tunnel under the World”, J.T. McIntosh’s “Hallucination Orbit”, Fritz Leiber’s “A Pail of Air”, and George Lefferts’ “The Parade”

The program opened with announcer Fred Collins delivering the countdown, leading into the following introduction (although later shows beginning with Episode 37, were partnered with Galaxy Science Fiction rather than Astounding Science Fiction):

“Countdown for blastoff. X minus five, four, three, two, X minus one. Fire! From the far horizons of the unknown come transcribed tales of new dimensions in time and space. These are stories of the future; adventures in which you’ll live in a million could-be years on a thousand maybe worlds. The National Broadcasting Company, in cooperation with Street & Smith, publishers of Astounding Science Fiction, presents X Minus One.”

The series was canceled after the 126th broadcast on January 9, 1958. However, the early 1970s brought a wave of nostalgia for old-time radio; a new experimental episode, “The Iron Chancellor” by Robert Silverberg, was produced in 1973, but it failed to revive the series.

The Stars

There were no regular stars in X Minus One. The series featured a rotating cast of voice actors who brought the various science fiction stories to life.

Some of the notable performers who appeared in the series included William Redfield, Mandel Kramer, and Staats Cotsworth.

Other Information

X Minus One was produced in cooperation with the publishers of Astounding Science Fiction magazine (later renamed Analog Science Fiction and Fact). The series was known for its high production values, with realistic sound effects and atmospheric music enhancing the adaptations of classic science fiction tales.

While the series was not a major ratings success during its original run, it has since gained a devoted following among old-time radio enthusiasts and science fiction fans. The series has been praised for its faithful adaptations of literary works and its ability to capture the sense of wonder and imagination that characterized the golden age of science fiction.

In addition to the 1973 experimental episode “The Iron Chancellor”, there have been efforts to revive X Minus One in other media.

Overall, X Minus One stands as a testament to the enduring appeal of classic science fiction and the power of radio drama to transport listeners to new and imaginative worlds.
