Planet of the Apes

Armando and Caesar (Roddy McDowall), a young chimpanzee horseback rider in Armando's circus, distribute flyers around a large city to advertise the circus' arrival. Armando warns the chimpanzee to be careful....should anyone learn his identity as the son of Cornelius and Zira, it would mean their deaths. They see apes performing various menial tasks, and are shocked at the harsh discipline on disobedient apes
