An examination of the heavy metal music subculture that tries to explain why, despite the longevity and popularity of the genre, fans are marginalized and ridiculed for their passion.
Sam Dunn is a anthropologist and a lifelong metal fan. After years of studying diverse cultures, Sam turns his academic eye a little closer to home and embarks on an epic journey into the heart of heavy metal. His mission: to figure out why metal music is consistently stereotyped, dismissed and condemned, even while the tribe that loves it stubbornly holds its ground -- spreading the word, keeping the faith and adopting styles and attitudes that go way beyond the music.
Sam visits heavy metal landmarks as far flung as L.A.'s Sunset Strip, the dirty streets of Birmingham and the dark forests of Norway. Along the way, the two sides of Sam Dunn -- curious anthropologist and rabid fan -- collide, as Sam explores metal's obsession with sex, religion, violence and death, meets his heroes, and discovers some things about the culture that even he can't defend.

On the coast, two worlds collide. Coasts are the most dynamic and challenging habitats in the ocean - that brings great rewards but also great danger. The extraordinary animals that live here must find ingenious ways to cope with two very different worlds. This episode is a rollercoaster ride of heart-stopping action and epic drama, peopled with characters from the beautiful to the bizarre. We meet fish that live on dry land and puffins that must travel 60 miles or more for a single meal, and witness a life-and-death struggle in a technicolour rock pool. In a secluded cove in the Galapagos, sea lions feast on 60kg tuna. It should be impossible - tuna are usually far too fast for sea lions to catch. But here the sea lions club together to herd their prey inshore. Once trapped in the shallows, these huge fish are easy pickings. As the tide recedes in Brazil, lightfoot crabs leap from rock to rock, desperately avoiding the water - their lives depend on it. Moray eels launch themselves from rock pools, jaw gaping. Then octopuses, too. Both crawl across dry rock to set their ambush. Elsewhere, the ever-changing tides create rock pools. But these temporary worlds are a battleground. Predatory starfish turn a magical garden into the stuff of nightmares.

Coral reefs are the nursery for all life in the oceans, a remarkable ecosystem that sustains us. Yet with carbon emissions warming the seas, a phenomenon called 'coral bleaching' -a sign of mass coral death- has been accelerating around the world, and the public has no idea of the scale or implication of the catastrophe silently raging underwater.
Chasing Coral taps into the collective will and wisdom of an ad man, a self-proclaimed coral nerd, top-notch camera designers, and renowned marine biologists as they invent the first time-lapse camera to record bleaching events as they happen. Unfortunately, the effort is anything but simple, and the team doggedly battles technical malfunctions and the force of nature in pursuit of their golden fleece: documenting the indisputable and tragic transformation below the waves. With its breathtaking photography, nail-biting suspense, and startling emotion, Chasing Coral is a dramatic revelation that won't have audiences sitting idle for long.

Nick Yarris, a convicted murderer who has spent 23 years on Death Row and was released in 2004 when DNA evidence proved he was innocent of the crime, tells his story. In a non-linear structure, he reveals his early life, youthful transgressions, arrest, and time on death row, with several twists and turns. This gripping documentary reels you in, closer and closer, finally playing its hand in the closing moments.

Austrian director Michael Glawogger travels to five countries to focus on some of the worst jobs imaginable: Ukrainian miners crawl into tiny cracks in old coal pits to scratch out a few bags of winter fuel; Indonesian workers trudge long distances carrying baskets with hundreds of pounds of sulfur chunks extracted from a steaming mountain; Pakistanis risk explosions and burial under tons of scrap iron as they dismantle huge carrier ships. The visuals are everything here. Despite the hardships depicted, many sequences have a dreamlike beauty. In addition, the director has a bone-dry sense of irony; during the Ukraine scenes, he frequently cuts away to a statue of Stakhanov, the "hero" lauded by the Soviets for his superhuman work habits. He also shows us an old German smelting works that's been converted into a theme park.

An astonishing journey revealing the awesome power of the natural world. Over the course of one single day, we track the sun from the highest mountains to the remotest islands, from exotic jungles to urban jungles. Breakthroughs in filmmaking technology bring you up close with a cast of unforgettable characters: a baby zebra desperate to cross a swollen river, a penguin who heroically undertakes a death-defying daily commute to feed his family, a family of sperm whales who like to snooze vertically, and a sloth on the hunt for love.
Told with humour, intimacy and a jaw-dropping sense of cinematic splendour, Earth: One Amazing Day highlights how every day is filled with more wonders than you can possibly imagine- until now.
