Though Fred Freiberger was credited on screen as producer for the Night of the Torture Chamber, he was fired before filming began on this show. John Mantley produced this show uncredited.
West and Gordon first met the Governor and Miss Piecemeal "a year earlier" in The Night the Wizard Shook the Earth (1965).
The vase destroyed in this episode is identical to the one that is destroyed in The Night of the Howling Light (1965).
Alfred Ryder also played a guest character with the first name of "Horatio" in The Night of the Deadly Bubble (1967).
At the end of the episode, the governor uses his right hand to shake Hands with Jim West and Artemis Gordon. The governor is supposed to be left handed. This may seem odd, but is not, as it is customary to shake hands with the right hand in Western countries as the right hand is thought to be closer to the heart.
