James Cameron is in the highest echelon of successful movie directors. His monster hits include "Titanic," "Avatar" and "The Terminator" series. In his latest film he is listed as the producer of the escape thriller "Sanctum," which is based on a harrowing true story experienced by co-writer Andrew Wright.
It follows a team of daring cave-diving adventurers. They set out to explore one of the most complex and dangerous subterranean cave systems in the world. A hurricane strikes their remote island while they are still underground. They soon become trapped in the flooded caves with no obvious way out.
What follows is a predictable tale of desperate people trying to escape from their terrible situation. As they try to find an exit to the upper world, they go deeper into darkness with fatal consequences.
There are some stunning scenes of natural beauty in the style of National Geographic. But the realistic gut-wrenching events lead to tangible feelings of claustrophobia and despair. Overall, watching this harrowing movie turns out to be a real ordeal for the viewer.
