POLE TO POLE Airs Sunday, March 25, at 8 p.m. ET/PT PLANET EARTH's premiere episode, "Pole to Pole," ties the series together with a fresh understanding of how life in every nook and cranny of the globe is connected — from the highest mountains and darkest caves; shallowest water and deepest oceans; ice-covered lands and great plains; untamed jungles and giant forests; to freshwater and the harshest deserts. The sunward tilt of Earth's orbit dictates all our lives, creating the seasons that trigger one of the greatest spectacles in the world — the mass migration of animals. It's a unique view of the majesty of our planet and the amazing creatures that live here.

MOUNTAINS Airs Sunday, March 25, at 9 p.m. ET/PT This episode tours the mightiest of mountain ranges and introduces a few of its extreme animal mountaineers — the mountain lion, snow leopard and puma, all rarely filmed creatures. CGI time-lapse footage brings the mysterious geological history of mountains to life, while flying alongside bar-headed geese provides a spectacular view of the Himalayas.

DEEP OCEAN Airs Sunday, March 25, at 10 p.m. ET/PT The ocean is by far the largest habitat on our planet and it remains almost entirely unexplored. This episode scans the ocean's vast surface and trolls its depths, revealing daytime hunters and night feeders, from dolphins to manta rays, and life among hot vents and underwater massifs, following the energy source between oceanic white tips, myctopids, tuna, whale sharks and petrels.
