国家地理百年纪念典藏55：窥探自然

Wild passions captures some of the most remarkable natural history sequences ever recorded and goes behind-the-scenes with filmmakers and cinematographers to hear the stories of what it takes to become a voyeur in the natural world. We follow filmmakers Carol and Richard Foster in the caves of Belize as they try to capture images of bats, Tom Mangelsen in the frozen tundra of Churchill, Manitoba wrapping up his ten-year shoot on his polar bear film, and Anton van Munster through the wilds of the Serengeti.
