A Different Cast Appeared in the Original Pilot Episode
The original pilot, entitled “Marooned,” did not air until 1992. The cast included John Gabriel as the Professor, as well as Kit Smythe and Nancy McCarthy as secretaries Ginger and Bunny. All three actors were replaced when CBS picked up the series. However, the character of Ginger was changed into a movie star, and Bunny became farm girl Mary Ann.
