Who doesn't love a good submarine movie? Jude Law plays a salty seadog fired from his job at an ocean salvage company who assembles a motley crew of pseudo-pirates to search the depths of the Black Sea for a sunken Nazi U-boat rumored to be loaded with gold. Director Kevin Macdonald (The Last King of Scotland) manages to shoot some tense aquatic adventure sequences. If only the stripped-down script for this underwater Treasure of the Sierra Madre rehash were as interested in its plot as in the heated arguments among the ensemble crew members. 115 minutes R.
