This awe-inspiring documentary charts James Cameron’s expedition to the bottom of the Mariana Trench, the deepest part of the world’s oceans, in his deep-diving submersible. 

Venture into the least known and explored place on earth

More than 50 years ago, two men climbed into a massive, blimp-like submersible, descended about 35,800 feet (10,912 meters) to the deepest point in the ocean, and became the first people to observe the dark underworld of one of Earth’s most extreme environments. No one had been back since, until March 26, 2012, when James Cameron, a National Geographic explorer-in-residence, made a record-breaking solo dive, piloting the Deepsea Challenger to the ocean’s depths. He squeezed into a pilot sphere so small he could not extend his arms. As he maneuvered on the ocean floor amid unexplored terrain and strange new animals, Cameron filmed footage for this feature-length documentary and collected samples for historic research. Why? To promote exploration and scientific discovery.

Although best known for directing films such as Titanic and Avatar, Cameron is an avid explorer with 72 submersible dives to his credit – to depths of up to 16,000 feet (4,877 meters).

For Cameron, who explored the Titanic wreck during his production of the Academy Award-winning film, reaching the deepest point on Earth was a long-term goal. 

‘Imagination feeds exploration’, he says. ‘You have to imagine the possible before you can go and do it.’
