When director James Cameron made his record-setting solo dive to the bottom of the Mariana Trench, he brought with him an innovative six-camera high-definition 3-D system to capture the void - and any life within it

“We created a tiny camera that fits in a very small housing to sit out at the end of a camera boom on a one-person sub that was going down to 36,000 feet,” The Hollywood Reporter quoted Cameron as saying. “We developed a 1080p [pixel] camera that was about the size of your thumb that sat inside a little titanium housing, and we generated 3-D from it by essentially putting two housings side by side, because the interocular was small enough."

While we've seen small moments of footage from that historic expedition, the full amazing story of the feat - from engineering to construction to the dive itself  - will now be told in the upcoming theatrical release of "Deepsea Challenge 3D." Directed by John Bruno, Ray Quint and Andrew Wight, the film "tells the story of Cameron’s journey to fulfill his boyhood dream of becoming an explorer."

“James Cameron's Deepsea Challenge 3D is everything we’d dreamed it could be and more,” says Lisa Truitt, president of National Geographic Cinema Ventures and an executive producer of the film. “It’s a heart-racing film experience and an inspiring reminder that our beautiful planet still has much to explore.”

We've got our first look below. "Deepsea Challenge 3D" hits theaters August 8th.
