1 of 16Planet of the Apes
Apes might like the future world of this 1968 classic, but for humans it's less fun than a barrel of power-mad monkeys. We only realize the fate of the Earth as Charlton Heston comes across a rather famous monument on a barren beach and realizes that humans are their own worst enemies: "We finally did it. You maniacs! You blew it up!"
