If Rise of the Planet of the Apes was 50% apes and 50% humans, and Dawn of the Planet of the Apes was 65% apes and 35% humans, then War for the Planet of the Apes is 95% apes and 5% humans.
Here is where the conflict at the heart of War for the Planet of the Apes becomes small.
War for the Planet of the Apes will debut in theaters on July 14, 2017.
