There are places on Earth with no human history or memories, as remote from us as a distant planet. The deep-sea trenches are such a place – the deepest points on the planet, shrouded in eternal darkness, and home to an ocean's worth of scientific mysteries waiting to be solved.
As a boy, filmmaker James Cameron dreamed of a journey to the deepest part of the ocean. 'Deepsea Challenge 3D' is an astonishing documentary feature about the dramatic fulfilment of that dream, a historic expedition which took Cameron on the first-ever solo dive to the deepest place on the planet, deeper than Everest is high; the Mariana Trench in the Pacific Ocean.
It offers a rare glimpse into the dedication and passion Cameron (as expedition leader, submersible co-designer and pilot) shared with the mission’s international team to take on the seemingly impossible task— creating a sub, built in Sydney, that could withstand the crushing pressure almost 36,000 feet down. The risks were astounding. The footage is breathtaking.
