The Munsters Unaired Pilot

The first presentation was filmed in color and ran 16 minutes (later cut to just over 13 minutes). It was used to pitch the series to CBS and its affiliates. (The episode is available on the first season of The Munsters DVDs.) It never aired, but the script was reused as the basis for Episode 2, "My Fair Munster". The cast in the title sequence included Joan Marshall as Phoebe (instead of Lily), Beverley Owen as Marilyn, Nate "Happy" Derman as Eddie, Al Lewis as Grandpa and Fred Gwynne as Herman. Although the same house exterior was used, it was later changed to appear spookier for the series. This included adding the tower deck and Marilyn's deck, a new coat of paint and enlarging the living room. Although Grandpa had the same dungeon, Gwynne did not wear padding in the pitch episode, had a more protruding forehead, and was broad but thin. The most noticeable difference was his somber expression rather than his comic silliness during the series. Except for Marilyn, the family had a blue-green tint to their skin. The biggest character difference was that Eddie was portrayed by Derman as a nasty brat. Eddie, as played by Patrick, was mostly respectful.
The pilot title sequence had light, happy music borrowed from the Doris Day movie The Thrill of It All instead of the instrumental rock theme. It was also decided that Marshall too closely resembled Morticia Addams and that Derman was too nasty as Eddie, so both were replaced. On the basis of the first presentation, the new series, still not completely cast, was announced by CBS on February 18, 1964. A second black-and-white presentation was filmed with DeCarlo and Patrick. In this version, Eddie appeared with a more normal look, although his hairstyle was later altered to include a pronounced widow's peak.
