The next installment of this sci-fi is set in the 1990s, after a plague has wiped all dogs and cats from the face of the Earth; speechless primitive apes have therefore been domesticated and turned into first pets, then servants of humankind. Their continual mistreatment provokes one advanced ape from the future, Caesar, to lead a spectacular revolt. Starring Roddy McDowall, Don Murray, Ricardo Montalban.
