The Pacific Ocean covers one third of the Earth's surface. It is greater than all of Earth's land combined, holds half of our world's water, and hides the deepest place on our planet. It's where huge and iconic, rare and dazzling creatures call home - and where creatures yet to be discovered lurk. Over four cinematic episodes, Big Pacific breaks the boundaries between land and sea, moving throughout the Pacific Ocean to present a broad range of locations, species, natural phenomena and behaviours. Each episode focuses on an iconic characteristic of the Pacific: Passionate, Voracious, Violent, and Mysterious. Filmed in cinematic 4K, Big Pacific will present the ocean and its denizens in ways never before seen on television - exploring the monstrous to the minute; the alien to the intimate.
