La Grieta on AllMovie

The success of The Abyss led to slew of deep-sea adventures in 1989, including this silly monster movie from the director of Pieces and Slugs. Jack Scalia stars as the head of a rescue mission sent to retrieve a nuclear sub sunken off the coast of Norway, only to be menaced by phony-looking monsters and a ruthless corporate stooge (Ray Wise) trying to get everybody killed. Full Metal Jacket's R. Lee Ermey co-stars as another hard-bitten militarist, this time a ship captain, and the film features numerous poorly-done gore scenes including an exploding head and torn-off limbs. Deborah Adair is noteworthy as Scalia's ex, but the direction is poor and the monsters are likely to produce more in the way of sneers than cheers. See also Leviathan and DeepStar Six.
