This eight-minute educational film was produced by American publishing giant CRM/McGraw Hill Films in 1974 and tells the story of Plato’s “Allegory of the Cave” in a psychedelic style. It features actor Orson Welles as its narrator and was animated by illustrator Dick Oden.  There is little additional information available about the circumstances of this film’s production; however, its philosophical subject matter  — authority, obedience, perception and the nature of reality — were themes that were being explored in a number of experimental films and cartoons of the 1970s (see also “The Return to Olympus” and “Metamorphoses”). An intriguing description of the film suggests that it was made in order to educate workers and those in positions of leadership about “the strategies that managers use to train and supervise their employees.”

In its sit-com sensibilities and with its extremely catchy theme song, this Hanna-Barbera series closely followed the model of its famed 1960s predecessors, “The Flintstones” and “The Jetsons,” though it lasted only one season (13 half-hour episodes). It depicted a regular family circa 63 CE — dad Augustus “Gus” Holiday, his wife Laurie, their daughter Precocia, their teen-aged son Happius (nicknamed “Hap”), and their pet lion Brutus — as they deal with distinctly modern problems, in particular with their landlord Mr. Evictus of the Venus de Milo Arms (who was voiced by Dom DeLuise).
