If you're looking for a political message in Kingdom of the Planet of the Apes, consider the following: The story begins "many generations" after the death of the previous reboot trilogy's hero, Caesar. Caesar was the first ape to speak, following the spread of a strange virus. Eventually, he became the leader of the apes in a war against the remnants of humanity. Caesar's teachings—apes should not kill each other, and apes are stronger together—have become quasi-religious dogma (ape-ma?) amongst the apes who live on in the post-apocalyptic world.
But those beliefs have been perverted by an authoritarian sect run by Proximus, a strutting, vainglorious bonobo bent on unifying and dominating the fragmented ape clans into something greater. Proximus preaches strength and glory; it turns out the bonobos, like all men, are obsessed with Rome. But his footsoldiers massacre peaceful ape clans, and his murderous forces wear face coverings and are known as "masks." His whole kingdom appears to be built on personal whim and something resembling slavery. Talk about a banana republic.
