Trivia: This is basically the same plot from season three episode Three Wishes. Here Darrin is told there is "fog" preventing his flight out; season three it was "snow." In both episodes, Endora tests Dartin's faithfulness by juxtaposing him with a beautiful girl.
Trivia: Elizabeth Montgomery (Samantha) was actually able to twitch her mouth quickly to move her nose back and forth. Many believe that the editors sped up the film to enhance her twitch.
Trivia: Because Erin Murphy, who played Tabitha, was ill, her fraternal twin sister Diane took her place in this episode. By this time, Erin and Diane didn't resemble each other as much as they once did, and it was obvious to regular viewers of the show that it wasn't the Tabitha they were used to seeing. The producers received several letters asking "Who was that?"
Trivia: The Screen Gems sets of Bewitched and I Dream of Jeannie were right next to each other at the studio, and many of the actual sets and props were shared between the two shows. Both shows also shared Dick Albain, the Special Effects expert, who worked on the two shows for quite awhile.
Trivia: Since the filming crew had to float objects around the set, they spray-painted the wires to make them less visible.
Trivia: Elizabeth Montgomery herself chose the name 'Tabitha' for the name of her TV daughter; actor Edward Andrews had a daughter with that name and Elizabeth liked the 'old fashioned' way it sounded. But at first the name was spelled 'Tabatha' in the credits and Elizabeth disliked it.
Trivia: When Uncle Arthur loses his powers,Samantha offers to teach him how to drive. This is a reversal of the season 1 episode, "Red Light, Green Light", where Paul Lynde - playing a driving instructor before he was later cast as Uncle Arthur - tried to teach Samantha how to drive. (00:14:30)
Trivia: Dick York played Darrin Stephens from 1964 till '69, when he left under supposed false pretenses, including those stemming from his addiction to painkillers (for his chronic back pain), there may have been other reasons for his leaving or possible dismissal. Dick Sargent took over the role in '69, and played Darrin until the show ended in 1972.
