While making The Munsters, Yvonne De Carlo (Lily Munster) and Fred Gwynne (Herman Munster) became good colleagues 🤝. At first, Gwynne and co-star Al Lewis were unsure about De Carlo joining the cast because of her successful film career 🎥. But their worries went away quickly as De Carlo took her role seriously and professionally 🎭. She played Lily Munster by following the advice to act like Donna Reed, giving her character a kind and caring personality, even though she was a spooky mother 🧛‍
