Sanctum (Single Disc)

Sanctum, the epic underwater adventure from three-time Academy Award-winning executive producer James Cameron (Avatar, Titanic), 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 of Moulin Rouge!, Mission: Impossible II) has explored the South Pacific’s Esa’ala caves for months.  But when his exit is cut off in a flash flood, Frank’s key team—including 17-year-old son Josh (Rhys Wakefield of The Black Balloon, Broken Hill) and financier Carl Hurley (Ioan Gruffudd of Fantastic Four series, W.)—is forced to radically alter plans.

With dwindling supplies, the crew—including Carl’s girlfriend, Victoria (Alice Parkinson of Where the Wild Things Are, X-Men Origins: Wolverine), and Crazy George (Dan Wyllie of Muriel’s Wedding, Chopper)—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?
