18. BATTLE FOR THE PLANET OF THE APES (1973)
BFPOA features plenty of ape-on-ape action, but little else. In a prologue, John Huston (hiding behind ape makeup and, no doubt, laughing all the way to the bank) lends his baritone to catch us up on some of the four previous Apes flicks. Then gorilla general Aldo tries to overthrow the benevolent Caesar (Roddy McDowall) while a posse of radioactive human mutants (their most obvious symptom is an allergy to acting) plan a race war.
