Monsters We Met is a documentary produced by the BBC that later aired as a special on Animal Planet in 2004 (under the title, Land of Lost Monsters) which also included footage from Walking with Beasts and Walking with Cavemen (both also made by the BBC). The show used computer-generated imagery to recreate the life of the giant animals that lived during the last ice age and explains how early humans encountered them. It also features humans as the main reason for the extinction of all great animals.
