In this episode, Henry Jones introduces himself as "Chester Dolenz". In his previous appearance in Run, Steve, Run (1974), Dolenz introduces himself as "Jeffrey Dolenz".
Obvious body doubles used for Oscar Goldman near the end of the episode. First, seen from behind in the trailer when Oscar meets his impostor robot. Next, when both Oscars jump out of the trailer and stand beside one another. Finally, the majority of the fight between Steve and the robot uses a body double for Richard Anderson.
Both Dr. Chester Dolenz and Oscar's reaction to the fight between Steve and the robot are totally indifferent. They just simply watch. One would think Oscar would be concerned for Steve as he's up against something just as powerful as him.
