Except for the series premiere, this is the only episode in which the special guest star (Robert Conrad) is listed at the beginning of the episode.
Look closely at the billboard on the studio wall at the beginning of the episode. It features a picture of Mitch's (Robert Conrad) latest movie, "The Wild Run." A few actual names such as Paul Krasny and others associated with Mannix are listed at the bottom of the credits. Conrad's picture is most likely from "The Wild Wild West."
This was Robert Conrad's first project after ending his four-year run starring in a TV western. Here, he plays a movie star making a western.
During the opening scenes the motorcycle used is a Husqvarna Cross.
Mike Connors and Robert Conrad would have one other shared listed credit, both being among the many stars in attendance for the All-Star Party for 'Dutch' Reagan (1985).
