March of the penguins (2005 )

Set against the barren splendour of the Antarctic, March Of The Penguins captures in extraordinary detail the remarkable lengths that Emperor penguins go to every year to breed their young. This most grueling of courtship rituals begins with a long, long walk and slide across hundreds of miles of ice, rock and snow in freezing temperatures that regularly dip below -20c. Hampered by icy winds and polar storms the parent penguins risk starvation while guarding the single egg - not easy when contact between the egg and the frozen ground will prove fatal to the unborn chick ? and face the perils of a trek back to the ocean in search of food, where predators including leopard seals lie in wait.
