The producers of Planet Earth explore some truly remarkable creatures and their unique habitats, many of which have never been captured on camera before. Star nosed moles, Zambian bats, and the Vogelkop bowerbird are just a few of the creature's you'll encounter as the filmmakers take viewers to distant continents, using state-of-the-art filming techniques to drift along with migrating elephants, soar through the sky with monarch butterflies, and witness a mating battle (also known as a "heat run") between male humpback whales. A two week visit with some Komodo dragons allows us to witness with striking detail how the mighty, ancient beasts can manage the unique feat of taking down an animal that towers over them in size. The series concludes with a "making-of" special which reveals how the dedicated filmmakers worked for more than four years to deliver a nature series with the power to take your breath away. Narrated by David Attenborugh.
