The fifth and final film in the APES franchise finds the title characters battling mutant humans. Roddy McDowall returns as Caesar, and Claude Akins and John Huston provide support to help bring the series full circle.

Roddy McDowall and Don Murray star in the fourth PLANET OF THE APES film, which takes place in the then-future 1990s! In a political allegory timed to coincide with the black power movement of the early 1970s, the enslaved apes plot to overthrow the human race that has oppressed them; this ambitious and entertaining sci-fi classic served as a template for last year's RISE OF THE PLANET OF THE APES.

When chimpanzees Cornelius and Zira (Roddy McDowall and Kim Hunter) mysteriously arrive on Earth in a spaceship, they are greeted with wonder and quickly become a media sensation. But this initial excitement turns to suspicion, and the chimp couple find themselves victims of a high-level conspiracy.
