Almost all of the movies in the Planet of the Apes franchise focus on answering an understandable question: How did this planet become, well, a planet of the apes? The original 1968 movie and infamous 2001 Tim Burton remake are about astronauts who are stunned to realize the planet they crash-landed on was Earth all along, and the first sequel ends with the planet getting blown up. But every other movie (and there have been 10 in total) has been about the downfall of humanity and the rise of the apes.
