The World's Biggest Cave

In 2009 a team of British cavers went on an expedition deep within the jungle of central Vietnam. To their amazement they discovered an enormous cave which they believe to be the biggest in the world. The team, the first humans ever to enter the cave, traveled 6 kilometers underground until their way was blocked by a gigantic rock face they dubbed 'The Great Wall of Vietnam'. Now they have returned, but this time with the right equipment to climb the wall and with a geologist and zoologist to discover if this is indeed the Biggest Cave in the World and what secrets lie deep within?

The Last Maneater: Killer Tigers of India

Sunderbans (Forest of Beauty) is in West Bengal, India, and is the only place on Earth that is the natural habitat of Royal Bengal Tigers that have never known to be fearful of humans. One tiger has been known to kill three fully grown men, leaving behind orphans and widows who belong to poor tribes, dependent on harvesting wild honey and fishing, in a swampy mangrove region. About 80 people are killed annually by these ferocious beasts with razor-sharp jaws, whose forepaws can shatter bones, and sharp teeth can pierce a skull in one bite. Amidst religious superstitions, the narrator attempts to explain the cause behind their taste for human meat in a region devoid of electricity, roadways, firearms and safe drinking water, and why the villagers continue to live there despite of being stalked and mauled on land and water alike.

An Otter Study

An Otter Study is a 1912 British short black-and-white silent documentary film, produced by Kineto, featuring an otter in its natural habitat, including groundbreaking footage of underwater hunting scenes. The film provided a novel treatment of the creature, which had previously appeared on film only as the victim of hunt films, with the unique underwater footage, shot by a cameraman behind glass in a tank concealed on the bed of the river in the opening scene, and a concluding scene, excised from the surviving print, in which it escapes the hunters. It was long thought lost until footage from a 1920s Visual Education re-release of the film, re-edited under the supervision of Professor J Arthur Thomson of Aberdeen University's Natural History Department, was rediscovered.
