Return to the Planet of the Apes is a short-lived animated series, by DePatie-Freleng Enterprises in association with 20th Century Fox Television, based upon Planet of the Apes by Pierre Boulle. Boulle's novel had previously inspired five films and a TV series, beginning with the 1968 film Planet of the Apes starring Charlton Heston. Unlike the film, its sequels, and the 1974 live action TV 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 movie which were changed due to budgetary limitations in the late 1960s.
