Underwater, nobody can hear you scream. But you can still get chills watching this submerged supernatural chiller. The isolated haunt is a WWII submarine adrift in the Atlantic after taking aboard a few stranded survivors...and something else (cue creepy music now). Thanks to some eerie coscreenwriting by Darren Aronofsky (Requiem for a Dream), minds get tricks played on them and bodies begin piling up, even if the whole thing is a tad too murky.
Bruce Greenwood, Olivia Williams and Scott Foley give wicked performances as the final lot left to deal with the mysterious mess, doing their part to keep this sucker at "see" level.
