With a production budget of $25 million, the makers of Blue Planet: Seas of Life crafted this epic story of life on Earth. Five years in production, with over 2,000 days in the field, using 40 cameramen filming across 200 locations, and shot entirely in high definition, Planet Earth is an unparalleled portrait of the "third rock from the sun." This stunning television experience captures rare action in impossible locations and presents intimate moments with our planet's best-loved, wildest, and most elusive creatures. Employing a revolutionary new aerial photography system, the series captures animal behavior that has never before been seen on film. The series features high-definition footage from outer space to offer a brand-new perspective on wonders such as the Himalayas and the Amazon River. From the highest mountains to the deepest rivers, this blockbuster series takes you on an unforgettable journey through the daily struggle for survival in Earth's most extreme habitats. Planet Earth goes places viewers have never seen before, to experience new sights and sounds. The set contains the original U.K. broadcast version, including 90 minutes of footage not aired on the Discovery Channel's U.S. telecasts, and features narration by natural history icon David Attenborough. The standard edition also features 110 minutes of behind-the-scenes footage -- one 10-minute segment for each episode, and Planet Earth - The Future, a three-part, two-and-a-half-hour look at the possible fate of endangered animals, habitats, and humanity. Following the environmental issues raised by Planet Earth, this feature explores why so many species are threatened and how they can be protected in the future.
