On March 25th, 10 p.m. ET, world famous director James Cameron became the first human to reach the 11-kilometer-deep of the Mariana Trench in a custom-built Deep Sea Challenger submersible.

As a National Geographic “explorer on a mission” the filmmaker is shooting “Deepsea Challenge” there, which is a new 3D documentary film about the incredible expedition to one of the most extreme and dangerous environments on Earth. Cameron plans to take multiple dives to the point he already reached, exploring the dark underworld of the Pacific's Mariana Trench.

See below a short photo report about the expedition from James Cameron's Deepsea Challenge website. Enjoy the photos!
