The creators of Blue Planet: Seas of Life reunite to celebrate our remarkable planet as never before thought possible with a stunning trip into the wilderness shot on revolutionary high-definition cameras over the course of five years, and utilizing 40 cameramen in 200 locations. These are the scenes that simply were not possible with older filmmaking technology, and from the highest mountain peaks to the deepest river floors, Planet Earth sets out to capture on camera the most elusive creatures every known to humankind. Acclaimed actor David Attenborough narrates as the filmmakers of Planet Earth take viewers on a journey that is truly out of this world. The version of this series that aired on the Discovery Channel for American audiences featured alternate narration by actress Sigourney Weaver. ~ Jason Buchanan, Rovi
