The miniature spaceship prop was the same one used in the classic 1956 film Forbidden Planet.

Jack Klugman is also in "A Passage for Trumpet," "A Game of Pool" and "In Praise of Pip."

The short story written by Richard Matheson, was his first attempt at sitting down and penning a science fiction story.

Opening Narration
Narrator: Picture of the spaceship E-89, cruising above the thirteenth planet of star system fifty-one, the year 1997. In a little while, supposedly, the ship will be landed and specimens taken: vegetable, mineral and, if any, animal. These will be brought back to overpopulated Earth, where technicians will evaluate them and, if everything is satisfactory, stamp their findings with the word "inhabitable" and open up yet another planet for colonization. These are the things that are supposed to happen . . . Picture of the crew of the spaceship E-89: Captain Ross, Lieutenant Mason, Lieutenant Carter. Three men who have just reached a place which is as far from home as they will ever be. Three men who in a matter of minutes will be plunged into the darkest nightmare reaches of the Twilight Zone.

Closing Narration
Narrator: Picture of a man who will not see anything he does not chose to see--including his own death. A man of such indomitable will that even the two men beneath his command are not allowed to see the truth; which truth is, that they are no longer among the living, that the movements they make and the words they speak have all been made and spoken countless times before--and will be made and spoken countless times again, perhaps even unto eternity. Picture of a latter-day Flying Dutchman, sailing into the Twilight Zone.

This episode is based on the short story "Death Ship" by Richard Matheson. The story was first published in Fantastic Story Magazine March, 1953, and later included in Matheson's Shock! collection Dell, 1961.
