We recently had an opportunity to speak with director Alister Grierson, writer Andrew Wight, and executive producer James Cameron, as well as actors Richard Roxburgh, Ioan Gruffudd, Alice Parkinson, and Rhys Wakefield. We had a chance to discuss the new film, shooting it in 3D, working underwater and the true story that the movie is based on. To watch our exclusive interview please click on the video clip below.

The 3D 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. 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. 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 3D 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. Sanctum was inspired by the film's co-writer Andrew Wight's near-death experience of leading a diving expedition miles into a system of underwater caves, then having to find a way out after a freak storm collapsed the entrance.
