Did You Know?


This episode, which was one of John Erman's earliest jobs as a director, depicts Earth soldiers who have been captured and are being tormented by aliens on a mostly barren set consisting of a few rock-like props and doorways. It bears many striking similarities to the third season episode of Star Trek: The Empath (1968), also directed by Erman. Kirk, Spock, and McCoy (and the Empath, played by Kathryn Hays) spend the majority of that episode on a mostly bare set consisting of a few props and dark curtains, also being tormented by aliens.

Ebonite Interrogator: We are not at war here. The grief and loss we caused your planet was an accident. We promised we would do anything to rectify this unforgivable mistake. But we cannot sanction the continuation of such immoral and inhuman experimentation.
Commanding General: Inhuman? What do you know of humans, sir?

When Do We Turn on Each Other?
6 January 2015 | by (United States) – See all my reviews

This is quite a good study in human nature and includes some fine acting performances, including one by Martin Sheen. A group of intergalactic warriors are put in a prison camp on a remote planet and interrogated by the aliens there. Their understanding is that they are at war with these folks and the revert to the old name, rank, and serial number stuff. Unfortunately for them, the tactics employed are those often used. Divide and conquer, keep them guessing, turn them against each other. The aliens have a kind of want/weapon that can steal a person's speech or make them blind, or whatever is necessary to put them in a weakened position. The neat thing about this episode is that there is a kicker her which I will not mention. The interaction among the players is quite realistic and the audience is left out of the loop for most of the show. This is as much a psychological drama as it is science fiction. Well written and well presented.
