Trivia: Beverly Owen played the part of Marilyn for thirteen episodes believing the show would flop. When The Munsters became a hit, she started crying because of being away from her boyfriend who lived in New York. She was let go and the part of Marilyn went to Pat Priest who had such an uncanny resemblance to Beverly that people watching the show never knew the difference.
Trivia: From its inception, "The Munsters" was supposed to be produced in full color, and its earliest pilot was, in fact, shot in full color. The only reason the series was shot in black and white was because both CBS Television and Universal Studios refused to pay the additional $10,000 per episode for color.
Trivia: Fred Gwynne (Herman) in real life was 6 feet 5 inches tall. In order to achieve the character, he was fitted with shoes that were at least four inches thick in the soles. The make up for his face and head added the rest to make him 7 feet 3 inches tall, and the air cooled suit added girth, and weighed 40 to 50 pounds.
