I Dream Of Jeannie: Then, Now, and Fun Facts About the Show
No Theme Song?

When the second season of the show debuted, it was also the first time for the audience to hear the show’s (now) iconic theme song also showed up with the first season shot in color. It was filmed in black and white, and the show’s producers played around with a few various options for a song but could never decide on one until the following season.
The Marriage Mistake

Barbara Eden was deadest against the wedding between Jeannie and Tony. She pointed out that Jeannie was first and foremost not a human. She also realized that it would break the show’s sexual tension and destroy its credibility. Of course, Jeannie’s “genie” nature was addressed in the show and became the major conundrum of the episode because genies cannot be photographed.
