Actor Bill Dana makes a cameo appearance as a man-in-the-street. He is a brother of series' composer/conductor Irving Szathmary. Dana would be brought in as 99's Control partner for season five's "Ice Station Siegfried", as Don Adams refused to participate, deeming the episode as a poor retread of season four's "Schwartz's Island".
This episode was directed by James Komack that would later appear as Uncle Norman on ABC's "The Courtship of Eddie's Father.
