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: 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: 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.
