Narrator Tom Hanks and the crew will reveal perils and breakthroughs behind the lens of this milestone nature series — trekking through corrosive waters 14,000 feet up in the Andes to film flamingos, weathering Amazonian lightning storms, forging bonds between a wild puma and its longtime cameraman, and pioneering cinematography from cameras mounted on the back of a whales. The special will explore the dedication, fieldcraft, humor, heart and innovation that came together to create one of the most ambitious wildlife series ever produced. “The Americas” is executive produced by renowned Emmy and BAFTA Award-winning wildlife producer Mike Gunton (“Life,” “Planet Earth II,” “Dynasties”) for BBC Studios Natural History Unit, the best-known and most respected producers of natural history content in the world, in association with Universal Television Alternative Studio, a division of Universal Studio Group.
