Filmed with state-of-the-art technology over 14 months, often in temperatures of -60 degrees, with Force 10 storms and tidal waves as an added bonus, this natural history of Antarctica comes from the coldest, wildest, most lonely, starkly beautiful and most inhospitable place on Earth. Here Sir David Attenborough discovers penguins by the millions, thousands of whales, half the world's seal population and seabirds galore.
