While Sanctum looks to be an average survival drama story - a la The Perfect Storm - the setting and influence of Cameron's 3D technology automatically set it apart. Designed to operate in extreme environments, the technology used to shoot the action-thriller will bring audiences on a breathless journey across plunging cliffs and into the furthest reaches of our subterranean world. Shot on location off the Gold Coast in Queensland, Australia, Sanctum employs 3-D photography techniques Cameron developed to lens Avatar. Soon, they are confronted with the unavoidable question: Can they survive, or will they be trapped forever?

With dwindling supplies, the crew must navigate an underwater labyrinth to make it out.

But when his exit is cut off in a flash flood, Frank’s team-including 17-year-old son Josh (Rhys Wakefield) and financier Carl Hurley (Ioan Gruffudd)-are forced to radically alter plans. Master diver Frank McGuire (Richard Roxburgh) has explored the South Pacific’s Esa-ala Caves for months. When a tropical storm forces them deep into the caverns, they must fight raging water, deadly terrain and creeping panic as they search for an unknown escape route to the sea.

The 3-D action-thriller Sanctum, from executive producer James Cameron, follows a team of underwater cave divers on a treacherous expedition to the largest, most beautiful and least accessible cave system on Earth. The film adaptation of that harrowing story is said to focus on “the unique relationship between father and son, and the fragility of that bond when faced with the onslaught of nature.'
