Return to the Planet of the Apes is a 1975 American Saturday morning animated television series based on the 1968 film Planet of the Apes and its sequels, which were, in turn, based on the 1963 novel of the same name by Pierre Boulle. Unlike the film, its sequels, and the 1974 live-action television series, which involved a primitive ape civilization, Return to the Planet of the Apes depicted a technologically advanced society, complete with automobiles, film, and television; as such it more closely resembled both Boulle's original novel and early concepts for the first Apes film which were changed due to budgetary limitations in the late 1960s.
