Prehistoric Planet is a re-version of the BBC's "Walking with Dinosaurs" and "Walking with Beasts" series, done by Discovery Channel and NBC for the Discovery Kids network.
 Though the producers kept most of the original animation, David Bock and Peter Sherman wrote new text for a younger target audience, narrated by Ben Stiller (in Season 1) and Christian Slater (in Season 2), and interspersed the scenes with occasional quizzes to act as bumpers around the commercial breaks.
 New music was incorporated as well.
 Most marketing and advertising for the series focused on the dinosaur episodes.
 In addition, the final episode, the "Prehistoric Planet Top 10" focused solely on the creatures from "Walking With Dinosaurs".
 Most of the graphic content from the shows were removed to be more appropriate for children, small content edits were also done to allow original programs to fit in the 23 minutes of non-commercial time that a normal half-hour program has on network TV, resulting in footage from the shows to be trimmed down.
 Only Season 1 has been released on home video and DVD.
Back With Two Beasts is the nineteenth album (and fourth collection of outtakes) by the Australian psychedelic rock band The Church, released in November 2005.
 The material was recorded during the "Uninvited, Like the Clouds" sessions but released first, as a teaser for that album, and was originally only available from the band's website or at their gigs.
 It was re-released by Unorthodox Records in 2009.
 The title is a play on the euphemism for sexual intercourse, "the beast with two backs", to which both of the titles on the band's previous self-released album, "Jammed", also referred.
Monsters We Met is a documentary produced by the BBC and later aired on Animal Planet in 2003 (under the title, Land of Lost Monsters) but also used footage from "Walking with Beasts" and "Walking with Cavemen" both made by 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 to the extinction of all great animals.
