Walking with Beasts (Walking with Prehistoric Beasts in North American releases) is a 2001 six-part television documentary miniseries, produced by the BBC Natural History Unit. It is the second installment of the Walking With. . . series and a sequel to Walking with Dinosaurs. Beasts takes place after the extinction of the dinosaurs 65 million years ago depicted in Walking with Dinosaurs, and recreates animals of the Cenozoic with computer-generated imagery and animatronics. Like Dinosaurs, its narrative is presented in the style of a traditional nature documentary. Some of the concepts it illustrates are the evolution of whales, horses, elephants and humans.
