Light is a fascinating phenomenon. Without light, there would be no cinema, no film – and no life. So light is at the origin of everything, and yet it remains invisible to the eye until it hits matter. This moment is – quite literally – the starting point of Thomas Riedelsheimer’s latest work, for the springtime spectacle of rainbow shreds in the cinematographer and documentary filmmaker’s flat became the starting point of a search for the origin of the images we form of this world. For this quest he dived deep into two spheres that seem to follow different laws but always strive to fathom the magical: physics and art.

Every year, on the steppes of the Serengeti, the most spectacular migration of animals on our planet: Around two million wildebeest, Burchell's zebra and Thomson's gazelles begin their tour of nearly 2,000 miles across the almost treeless savannah. For the first time, a documentary captures stunning footage in the midst of this demanding journey. The documentary starts at the beginning of the year, when more than two million animals gather in the shadow of the volcanoes on the southern edge of the Serengeti in order to birth their offspring. In just two weeks, the animal herd's population has increased by one third, and after only two days, the calves can already run as fast as the adults The young wildebeest in this phase of their life are the most vulnerable to attacks by lions, cheetahs, leopards or hyenas. The film then follows the survivors of these attacks through the next three months on their incredible journey, a trip so long that 200,000 wildebeest will not reach the end.

Journey with the musicians of the Berlin Philharmonic and their conductor Sir Simon Rattle on a breakneck concert tour of six metropolises across Asia: Beijing, Seoul, Shanghai, Hong Kong, Taipei and Tokyo. Their artistic triumph onstage belies a dynamic and dramatic life backstage. The orchestra is a closed society that observes its own laws and traditions, and in the words of one of its musicians is, “an island, a democratic microcosm – almost without precedent in the music world - whose social structure and cohesion is not only founded on a common love for music but also informed by competition, compulsion and the pressure to perform to a high pitch of excellence... .” Never before has the Berlin Philharmonic allowed such intimate and exclusive access into its private world.

This video examines the killer whale, one of nature's greatest predators. It is part of a multi-volume Time Warner series that markets the ferocious, killing aspects of various wild animals.

Fascinating footage of swooping bats, their remarkable habits and habitats, and close-up looks at their interesting yet eerie faces are featured in this documentary, volume seven of the Predators of the Wild series. Most bats eat insects, which may not always come to mind when one thinks of predators and prey -- although the fact that a swarm of bats can eat 30,000 pounds of insects in one night is staggering. Bats make up almost one-fourth of all of the mammals in the world, but only three species of bats are "true vampires" who rely on the blood of other animals for sustenance.
