As a movie about some people trying to overcome nature and escape a cave, Sanctum could have easily have made it to a cable network trying to present something a bit less whimsical than whatever SyFy was putting on that night. Based on the true and much less exciting story of documentary maker Andrew Wight, the movie tells the straightforward tale of a group of people stuck in a cave who must venture deeper into it to escape. As you might expect, the usual characters are here, from the hardened cave explorer Frank (Richard Roxburgh) who can't connect with his angry teenage son Josh (Rhys Wakefield) to the rich thrill-seeking sponsors of the expedition (Ioan Gruffudd and Alice Parkinson). With dialogue like, "There is no god down here!" the only thing keeping this movie from basic cable is producer James Cameron and his toys.
