Siberian Tiger, The Secret Kingdom

Filmmakers Alastair Fothergill and Keith Scholey chronicle a year in the lives of an Alaskan brown bear named Sky and her cubs, Scout and Amber. Their saga begins as the bears emerge from hibernation at the end of winter. As time passes, the bear family must work together to find food and stay safe from other predators, especially other bears. Although their world is exciting, it is also risky, and the cubs' survival hinges on family togetherness.

Every year, thousands of Antarctica's emperor penguins make an astonishing journey to breed their young. They walk, marching day and night in single file 70 miles into the darkest, driest and coldest continent on Earth. This amazing, true-life tale is touched with humour and alive with thrills. Breathtaking photography captures the transcendent beauty and staggering drama of devoted parent penguins who, in the fierce polar winter, take turns guarding their egg and trekking to the ocean in search of food. Predators hunt them, storms lash them. But the safety of their adorable chicks makes it all worthwhile. So follow the leader... to adventure!!
