Hey, they were the original Olsen twins! Fraternal twins named Erin and Diane Murphy were cast to share the role of the Stephens’ daughter, Tabitha. It is quite common for twins to be used, particularly for the parts of babies. Babies have their own personality, so at any given time if one does not cooperate with filming the other can be used.
One baby from the Murphy twins definitely cooperated more than the other. It was clear right away that Erin really took to acting and would be the star of the show, so she was used for close-up shots and speaking scenes, while Diane was primarily used in long shots.
It’s been said that Elizabeth Montgomery was not pleased when I Dream Of Jeannie debuted on NBC just one year after Bewitched was introduced on rival network ABC. In fact, the two shows were long compared while on air and the comparison remains even now!
Both shows were about gorgeous blonde women with magical powers – Jeannie was a 2,000-year-old genie who falls in love with a NASA astronaut – and they both shared similar plot lines at times. But Elizabeth never felt any personal animosity toward I Dream Of Jeannie’s stars Barbara Eden or Larry Hagman.
On April 4, 1968, Bewitched was interrupted to announce the tragic news that civil rights leader Martin Luther King, Jr. had been assassinated. Eerily, the first day of rehearsal for the show was on Nov. 22, 1963, the day of the assassination of President Kennedy.
