De Carlo died of natural causes Monday at the Motion Picture & Television facility in suburban Woodland Hills, longtime friend and television producer Kevin Burns said Wednesday.
De Carlo, whose shapely figure helped launch her career in B-movie desert adventures and Westerns, rose to more important roles in the 1950s. Later, she had a key role in a landmark Broadway musical, Stephen Sondheim's "Follies."
But for TV viewers, she will always be known as Lily Munster in the 1964-1966 horror movie spoof "The Munsters." The series (the name allegedly derived from "fun-monsters") offered a gallery of Universal Pictures grotesques, including Dracula and Frankenstein's monster, in a cobwebbed gothic setting.
