National Geographic's Most Amazing

A riveting 90 minute special that counts down dramatic events captured on film through the National Geographic lens. Five action-packed segments feature spectacular imagery and firsthand accounts from the scientists, journalists and filmmakers on the scene that let viewers experience thrilling moments of discovery, heart-pounding adventure, and shocking rarely seen animal behaviors. A base jumper equipped with a helmet-cam takes a mile-high free fall-but his parachute won't open. A cameraman films a shark swimming away-but the shark turns back for an unexpected close-up. A journalist and his crew duck for cover on a mountaintop in Afghanistan as their location comes under attack and bullets fly right over their heads.

It is perhaps the most intriguing story to have ever emerged from ancient Egypt - the mystery behind the famed boy-king Tutankhamen. Why did he die so young? Was he murdered? And is there an explanation for the legendary curse said to follow those who found his tomb centuries later? Now, for the first time, an international team of scientists is using state-of-the-art CT-scan technology to unveil the truth of what really happened 3000 years ago and unravel the mystery of King Tut's curse. It's an unprecedented look into Tut's life and death that will reveal answers about the man behind the golden mask in King Tut's Final Secrets.

In a clannish world, tattoos announce where you belong. They declare that the bearer is either one of "us" or one of "them" - and "they" are almost always taboo. Explore the realm of headhunters where tattoos were once a matter of life and death. Witness a bloody rite of passage in Africa as a boy goes under the knife to earn his literal stripes as a man. Tattoos serve as totems to human creativity, as well as testimony to our darker impulses. With a tattoo, we can literally draw the lines that divide the accepted from the taboo.

Where and when the next mega disaster will strike - volcanic eruption, earthquake, tsunami or hurricane - is the focus of scientists around the world. Join tsunami scientist Jose Borrero of the University of Southern California on his trip to visit Banda Aceh with a National Geographic film team, one week after the December 26, 2004, tsunami - a tsunami so strong it actually moved the island of Sumatra a hundred feet.

Over the centuries, explorers traded tales of a lost civilization amid the dense Amazonian rainforest. Scientists dismissed the legends as exaggerations, believing that the rainforest could not sustain such a huge population - until now. A new generation of explorers armed with 21st-century technology has uncovered remarkable evidence that could reinvent our understanding of the Amazon and the indigenous peoples who lived there. Using CGI and dramatic re-creations, National Geographic re-imagines the banks of the Amazon 500 years ago, teeming with inhabitants living in the Lost Cities of the Amazon.

They are giants-stretching more than 90 meters above the ground, with hidden gardens and mysterious predators thriving within their canopy. Climber Steve Sillett investigates their monster crowns while escaping crashing trees in the process. Down below, National Geographic Explorer-in-Residence Mike Fay charts the redwood range to size up the past and future of these primeval trees.
