Best Answer

Sanctum is based on the true events of the writer/producer of the film, Andrew Wright. Wright was cave-diving in Western Australia's Nullabor Plain, which is a frontier for cave exploration, when a freak storm hit the area and trapped Wright and about 15 other divers underground. The screenplay is loosely based on the events that transpired.

The movie is based on events that happened to one of the film's co-writers, Andrew Wight, who went deep-sea diving and ended up trapped with a group of other divers in an underwater cave system.
