This was the only time that Chuck Connors and Barry Atwater worked together as castmates, the two actors each later portraying a separate character named Janos Skorzeny, with Atwater's turn being as the vampire in The Night Stalker (1972) (the first of two TV movie pilots for the series Kolchak: The Night Stalker (1974)) and Connors's turn being as the werewolf in the series Werewolf (1987) who is the originator of the bloodline causing the werewolf curse of the show's protagonist, the latter character created by the writers as a reference paying tribute to his earlier namesake.
