What Pilot Episode?
Only a few people know about the pilot episode of the show. It was shot in color, though it was never shown on TV. The producers chose to shoot the other episodes in black and white for financial reasons, though it was very fitting for the show. It was also interesting that Lily and Ernest were played by other people and Lily had been called Phoebe back then.
The First Choice Was The Wrong Choice
When it comes to Eddie Munster, Herman Munster and Grandpa, they were not actually the first choice actors for the roles. Bert Lahr of the Wizard of Oz fame was initially approached to play Grandpa, while Bill Mumy was offered the role of Eddie Munster. John Carradine, meanwhile, was asked to play Herman. Luckily, they all declined and things worked out perfectly in the end.
