Planet Earth: The Complete Series (2007)

To call Planet Earth, the magnificent 11-part BBC documentary, just another nature series is like calling Antarctica just another big sheet of ice: Those unmoved by shots of prowling snow leopards and frolicking polar bear cubs are hereby directed to move to another world. And when Planet Earth: The Complete Series is viewed in one of the high-def formats (either Blu-ray or HD-DVD), the often gasp-inducing footage takes on a startling vividness and depth. EXTRAS Found only on the standard-def (!) five-disc set, they include a sobering 150-minute special about our planet's uncertain future.
