arrives at Exo-III to conduct a search for the missing archeological expedition of Dr. Roger Korby. On the bridge is also Christine Chapel, Korby’s fiancée. They get a signal from the planet, from Korby himself saying his team is alive and well but asking only Kirk to come down to the planet. However, once he’s told that Christine is aboard he’s glad to have her come down as well...Read the full recap
The old-style laser pistol that Brown uses is the prop from the pilot and "The Man Trap."
This episode produced a sequel, the Trek novel Double Double by Michael Jan Friedman (ISBN # 0-671-66130-2). In it another Brown android returns from an expedition, finds Korby and the others "dead," and creates a new Kirk android. The androids then again attempt to put Korby's plan into operation, taking over the Enterprise and Hood while arranging the removal of the original Kirk.
According to a SciFi Channel interview with Sherry Jackson (Andrea), when Kirk kisses her the second time in the episode, William Shatner went for an actual kiss rather than a "screen kiss" as she was expecting.
Associate Producer Robert Justman deliberately picked the shot of Ruk picking up Kirk and lifting him above his head, as the credit for actor Michael Strong appears on-screen.
Spock: Are you sure you recognize his voice?
Chapel: Have you ever been engaged, Mr. Spock?
Korby: Can you understand what I’m offering mankind?
Kirk: Programming. Different word, but the same old promises made by Genghis Khan, Julius Caesar, Hitler, Ferris, Maltuvis.
Korby: Are you with me, Captain?
Kirk: You've created your own Kirk. Why do you need me?
Korby: I created him to impress you, not to replace you.
Kirk: I'm impressed, Doctor... but not the way you think!
Korby: Can you imagine how life could be improved if we could do away with jealousy, greed, hate...
Kirk: It can also be improved by eliminating love, tenderness, sentiment--the other side of the coin.
Spock: You're going back down?
Duplicate Kirk: Mind your own business, Mr. Spock. I'm sick of your half-breed interference, do you hear?
Spock: Yes, very well, Captain.
Kirk: We humans are full of unpredictable emotions that logic cannot solve.
Kirk: The danger to you is Korby!
Ruk: I was programmed by Korby, I cannot harm him!!
Kirk: The Old Ones programmed you too! But it became possible to destroy them!
Ruk: That was the equation! (Ruk seizes Kirk, nearly crushing his chest) Existence! Survival... must cancel out... programming...
Kirk: Something bothering you, Mr. Spock?
Spock: Frankly, I was rather dismayed by your use of the term "half-breed," Captain. You must admit it is an unsophisticated expression.
Kirk: I'll remember that, Mr. Spock, the next time I find myself in a similar situation.
Written by horror author Robert Bloch, script references to the Old Ones is a sly wink to the HP Lovecraft Cthulhu Mythos.
What Are Little Girls Made Of?
The title refers to a nursery rhyme that suggests little girls are made of "sugar and spice and everything nice." Not Korby's girls; they're made of machine parts and electronics - cold and dispassionate things.
What Changed in the Remastered Version
General improvements cited on the main series page. The planet Exo-III receives a significant visual upgrade and new orbital shots of the Enterprise are included. A new clearer shot of the planet's surface is included.
The episode title is rather clever. Real girls, it suggests, are made of "sugar and spice and everything nice," while Korby's people are made of clockwork and electronics. It alludes nicely to the final theme of the episode: that people reinvented as androids, with carefully hedged limitations in their emotions, would be less than human. Inasmuch as this is what destroyed the civiliztion of Exo III, one might expect an archaeologist of Korby's skill and experience would realize the hazard. And he might have, were he not approaching the situation from a particular perspective, the revelation of which also occurs during the episode's final moments.
