Production Notes
The costumes were designed by William Ware Theiss who had thought of a cross design. During production of the episode, a censorship agent was sent to observe the episode to make sure there was no footage of cleavage on the side Sherry Jackson's costume. During that time, cleavage on the front was allowed, but cleavage on the side was banned from television. Sherry Jackson had to place tape on the sides of her costume to make sure that there was not a costume malfunction.

William Shatner was asked to shave his chest for the scene where his android is created because the director felt that the character would be clean shaven. During the scene, where William Shatner has dinner with his android, a split screen was used so that Shatner appeared to be eating dinner with someone who looked exactly like him.
