Sanctum (2011)

Master diver Frank McGuire (Richard Roxburgh) has explored the South Pacific's Esa-ala Caves for months. 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. With dwindling supplies, the crew must navigate an underwater labyrinth to make it out. Soon, they are confronted with the unavoidable question: Can they survive, or will they be trapped forever?

Shot on location off the Gold Coast in Queensland, Australia, Sanctum employs 3-D photography techniques Cameron developed to lens Avatar. 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.
