Almost as famous for his mentoring of undersea filming equipment as for the movies he's directed, James Cameron puts those developments to use as a producer of this frequently tense thriller. During a cave excursion, explorers become trapped, forcing them to do a lot of breath-holding as they try to find a way out through watery passages.
Cast members include Ioan Gruffudd ("Fantastic Four"), Richard Roxburgh ("Mission: Impossible 2") and Rhys Wakefield. DVD extras: "making-of" documentary; audio commentary by Wakefield, director Alister Grierson and co-producer and writer Andrew Wright; deleted and extended scenes. *** (R: AS, P, V) (Also on Blu-ray and Movies on Demand)Copyright © 2015, Los Angeles Times
