The Munsters – Beverly Owen was replaced by Pat Priest

Marilyn Munster

As the only non-horror character on the show, Marilyn was the ugly relative and the audiences introduction to the family. Originally the role was played by Owen (who was contractually obligated to take the role), and she left after 13 episodes because she wanted to get married and leave the role. She was replaced by Pat Priest who continued the role for 70 more episodes.
