"Tabitha" originated as a pilot that aired on ABC on April 24, 1976. The episode used the variant spelling "Tabatha" for the title, and starred Liberty Williams in the title role. Bruce Kimmel portrayed her brother, Adam Stephens. The major difference between the pilot and the series was that Adam was a full-fledged and mischievous warlock in the pilot, but was made a mortal for the series (thus making him the disapproving figure as Darrin had been). In the first pilot, Tabatha was an editorial assistant for the fictional "Trend" magazine, lived in San Francisco, and had a boyfriend named Cliff (Archie Hahn). She also contended with the supernatural antics of Adam. In situations that were very similar to "I, Darrin, Take This Witch, Samantha", the pilot episode of "Bewitched", Tabatha tells Cliff that she is a witch, who at first does not believe her, but later discovers that she is telling the truth. Also, much like her mother did when she used her powers to deflect the unwanted affections of Sheila Sommers, her father's former fiancée, Tabatha deflects rival Dinah Nichols (Barbara Rhoades) from seducing Cliff.
