The Munsters began as a pitch for a cartoon before Universal Studios and its creators settled on live actors, and this forty-five minute retrospective traces that decision through the show's run on CBS and its afterlife in reruns. CBS executive Mike Dann and series director Norman Abbot, both fixtures behind the camera rather than in front of it, talk through the casting choices and the network politics that shaped the series. Fan historians Don Glut and Bob Burns add context on why the show kept finding new audiences decades after production ended. The interviews carry the film: Yvonne De Carlo, Butch Patrick, and Al Lewis appear on camera, along with all three actresses who played Marilyn Munster over the show's short run, addressing why Beverly Owens left so early. Fred Gwynne had died before filming and is absent, though his castmates speak about working with him. The film also covers the post-series films, including Munster, Go Home! and Here Come the Munsters, in which Edward Herrmann took over the role of Herman.
