Filmmaker Alain Resnais documents the atrocities behind the walls of Hitler's concentration camps.

A raw and telling portrait of a people left behind by the modern world, inspired by the work of photographer Martin Martinček - whose pictures of the inhabitants of the Liptov region in central Slovakia, encompassed by the Tatra mountains, distilled entire lifetimes into luminous and intransient images. Dušan Hanák's continuation of these photographs takes the shape of a poetic visual essay, capturing more comprehensive vignettes of their isolated human experiences.

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!!

This documentary follows various migratory bird species on their long journeys from their summer homes to the equator and back, covering thousands of miles and navigating by the stars. These arduous treks are crucial for survival, seeking hospitable climates and food sources. Birds face numerous challenges, including crossing oceans and evading predators, illness, and injury. Although migrations are undertaken as a community, birds disperse into family units once they reach their destinations, and every continent is affected by these migrations, hosting migratory bird species at least part of the year.

A documentary of insect life in meadows and ponds, using incredible close-ups, slow motion, and time-lapse photography. It includes bees collecting nectar, ladybugs eating mites, snails mating, spiders wrapping their catch, a scarab beetle relentlessly pushing its ball of dung uphill, endless lines of caterpillars, an underwater spider creating an air bubble to live in, and a mosquito hatching.
