In 2011, Frozen Planet gave BBC viewers an unprecedented insight into life in the Poles.
But, going further than Series 1, it also explores life beyond the Poles - witnessing the wildlife dramas that play out in all the world's coldest regions: our high mountains, frozen grasslands, snowbound forests, and ice-cold oceans.From polar bears to penguins, Siberian tigers to snow monkeys, each species must overcome unique challenges to survive their extreme environments. Now, 11 years later, Frozen Planet II - presented by Sir David Attenborough - returns to the Arctic and Antarctic to observe the amazing species that thrive there.
