James Cameron’s ‘Deepsea Challenge 3D’ documentary released

In March 2012, film director James Cameron became the first person in history to solo dive the Challenger Deep, the deepest point of the Mariana Trench and the world, a staggering 6.8 miles (35,756 feet) below the surface of the Pacific Ocean.

For the dive, Cameron descended into the trench for more than two and a half hours aboard his custom-built 24-foot submersible, Deepsea Challenger, which actually shrank in size considerably due to the enormous pressure.

Now, more than two years later, Cameron is releasing “Deepsea Challenge 3D”, a documentary film chronicling his record breaking solo dive and the seven years of preparation that led up to it.

The film opened in U.S. theaters on Friday.
