Frozen Planet (2011)

Frozen Planet takes you on the ultimate polar expedition. This landmark 7-part series brings to the screen the two most remote and least hospitable areas on the planet: the frozen wildernesses of the Arctic and Antarctic. And yet, despite environments where temperatures reach minus 70 degrees Celsius and the sun doesn't shine for half the year, life flourishes. Prime attention is given to seals, penguins, and polar bears, but there's a great deal more: from slugs, snails, and caterpillars to minke whales, beluga whales, and narwhals, from seabirds and cod gathering by the millions to wolves tracking bison and caribou. There are breathtaking shots of the landscape as well, and portraits of the human element.
