A really funny badflique starring Peter Weller and Amanda Pays, among others. Undersea explorers find a Soviet science vessel on the ocean floor that appears to have been destroyed by mutiny. Despite signs of contamination, some of them sneak some vodka out to their (dry) habitat and guzzle it. Surprise! The vodka contains a genetic virus which kills one of them and converts his corpse to a semi-living Grue! Best part: While trying to throw it out the 'lift-lock' into the sea, the others accidentally cut off its leg, which slithers away into the bilge of their station. It then evolves into a large grody killing beast which begins to assimilate the others! Thus, my favorite phrase for a generic movie monster: the LEG.
