Did You Know?


James Goldstone, who directed the second pilot, Star Trek: Where No Man Has Gone Before (1966) was hired to direct this episode, because the production staff greatly praised his work. However, filming of this episode went two days over schedule (mostly due to the aforementioned script problems), resulting in eight shooting days. Goldstone was never re-hired. See more »

Superb Dark Story, Not A Typical Star Trek Episode
25 October 2016 | by Dan1863SicklesSee all my reviews

This is not a typical episode of STAR TREK. There is no happy ending. Kirk, Spock, and McCoy, don't work together as a team. Kirk fights, but he doesn't win; in fact he gets thrown around like a rag doll! He doesn't come up with any answers, and he doesn't make any heroic speeches. The main villain and his followers aren't really outwitted, they almost literally self-destruct. Nothing changes for the better, and when the truth is revealed no one is happy with what they discover!

Yet with all that, this is one of the strongest early episodes. Dr. Korby is one of the most sinister and chilling of all Star Trek villains. His downfall is chilling because his goals are so very seductive and universal. Who doesn't want to cheat death? Who wouldn't make the choice he made, and who wouldn't be driven mad by turning into what he became?

Michael Strong is superb as the most tormented of mad scientists, a villain who becomes increasingly repulsive until the shocking truth makes him appear more pitiable than anything else. Bear in mind, Strong was an actor who could play any part, from cold, calculating scientist to a blue collar slob. It's a hoot to watch this episode and then catch him in the old American Playhouse production of THE ICEMAN COMETH, where he plays Chuck the Bartender. ("Can ya imagine me having a robot wife, Kirk? The kind of robot that, if you lined up all the other robots she stayed with, they'd reach to Chicago!")

And speaking of robot wives, the stunningly beautiful Sherry Jackson is one of the most memorable and frightening of Kirk's many conquests, since she takes a stock fantasy figure and turns her into someone . . . or something . . . both chilling and pitiable. Her final cry ("love me") is a mini- tragedy that matches the major tragedy of Dr. Korby.

Robert Bloch wrote an incredible story here, a tragedy that has all the clammy, claustrophobic terror of PSYCHO and the creeping paranoia of the Cold War. The horror grips you and never lets you go. I don't know if this is great STAR TREK. But I know it's art. And I like it!
