Sci Fi History: Planet of the Apes (1968)

Planet of the Apes might be the most disturbing post apocalyptic film ever. Humanity devolved to little more than cattle. Meanwhile, apes became the planet's dominant species. The apes hunt people for sport and enslave them. The dominant species developed speech and advanced intelligence. On top of this, the film's star, Charlton Heston, was an A-list actor and hero. Despite this, not even Heston could not overcome this threat to humanity, which is part of the film's appeal. Moses could not escape the Planet of the Apes, so who could? In addition to Heston's helplessness, the end was particularly disturbing when his character discovers he is on Earth after a long space voyage. Lastly, the film dealt with racial tensions by focusing on three types of apes. Gorillas were the enforcers, chimps the intellectuals, and orangatans ruled. Each type of ape held their own prejudices against the other reflecting modern America.
