Journey into Amazonia features the swollen rivers, flooded forests and dense canopy of the vast rain forest recognized as one of Earth's natural wonders. For three years, producer Harry Marshall and his team braved sweltering heat and insect swarms to capture the changing seasons of a magical world. This three-part wildlife series offers an enchanting look at rarely seen creatures as they contend with the volatile waters of the world's largest river system. The river's rich, turbulent waters sustain a vast cast of characters, including seven-foot otters, fruit-harvesting fish, fresh water dolphins and manatees. On land, stealthy jaguars prowl, acrobatic monkeys defy gravity and keeneyed harpy eagles soar.
