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 non-avian 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.
BBC One aired the series weekly on Thursday nights, with a regular of repeats the following Sunday afternoon. In 2010, the series was repeated on BBC Three in omnibus format, as three-hour-long episodes.
