Two actors who would later co-star on Quincy M.E. (1976) appeared in this episode: Robert Ito (uncredited) and Val Bisoglio.
Guest star Ted Cassidy would later provide the growling voice for the title King of Monsters in the cartoon series Godzilla (1978), that character of course having quite the history with Raymond Burr in the films Godzilla: King of the Monsters! (1956) and Godzilla 1985 (1985).
