Round Planet explores the complex culture, society, and intelligence of our closest ancestors, the four species of great apes: the mountain gorilla, the chimpanzee, the bonobo, and the orangutan. Narrator Armstrong Wedgewood (Matt Lucas) takes us on a tour from Central Africa to Sumatra to explore the lives of these huge primates, taking delight-and sometimes liberties-in drawing parallels between the behavior onscreen and human society.
