In 2011, Frozen Planet gave BBC viewers an unprecedented insight into life in the Poles.

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. 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.

These are the last true wildernesses on earth; places so challenging for survival that only a heroic cast of animals can live here. From polar bears to penguins, Siberian tigers to snow monkeys, each species must overcome unique challenges to survive their extreme environments."
