nuclear arms race
Rise of the Planet of the Apes is a surprising addition to the typical summer blockbuster canon -- for one thing, it manages to entertain and challenge, without resorting to gratuitous violence to make its point. But there's a deeper subtext that is even more unexpected -- for this is a story in which we start to lose.
It was fashionable in the late 1960s and early '70s for science fiction films to attempt to out-dystopia each other -- see for example the notion in Soylent Green that post-industrial humanity snacks on itself to survive, the suggestion that only robots can be trusted to look after creation in Silent Running, and the climactic revelation in the original Planet of the Apes that a few generations from now, the nuclear arms race will end in mutually assured destruction. All these point to a simple philosophical idea: that humans cannot be trusted to care for ourselves or the planet we steward.
