Because Mission: Impossible and Star Trek were both shot on the Desilu lot, the two series always had some crossover with guest stars. But this episode features no less than six guest stars who also appeared in Star Trek: Antoinette Bower ("Catspaw"), Sid Haig ("The Return of the Archons"), Percy Rodriguez ("Court Martial"), Joseph Ruskin ("The Gamesters of Triskelion"), George Sawaya ("The Menagerie" and "Errand of Mercy") and Warren Stevens ("By Any Other Name").
The names of the Arabic characters are entirely made up: "Ibn Borca" means "son of a lady's veil" and "Fasar" means "to examine a urine sample". Jara, Musha, and Akim are not Arabic names either.
