On what should be a routine rescue mission during World War II, the submarine USS Tiger Shark picks up three survivors of a U-boat attack. As the crew is trapped together in the sub’s narrow corridors and constricted spaces, bizarre and frightening events begin to transpire. In a suspense-fueled race for survival, they must figure out the submarine’s past before it’s too late to resurface alive. Hauntingly directed by David Twohy ( Pitch Black ) and co-written by Darren Aronofsky ( Requiem for a Dream ), Below is a harrowing, otherworldly excursion into undersea terror. The superb cast includes Olivia Williams ( The Sixth Sense ), Bruce Greenwood ( Rules of Engagement ), Matthew Davis ( Blue Crush ) and Zach Galifianakis ( The Hangover ).
