Plot synapsis: Underwater mining rig, day 87 of a 90 day tour, goof-off sexist jerk wanders off and finds a sunken Russian freighter.
The cast consists of Peter Weller as the geologist boss, Richard Crenna as the semi-doctor and crewed by Ernie Hudson (who gets some of the best lines and steals his scenes), Amanda Pays (and her annoyingly fake accent) Daniel Stern, Michael Carmine, an adorable Lisa Eilbacher, Meg Foster (what IS it about her eyes? And why was she trying so hard to do a crappy acting job?), and the wonderful Hector Elizondo.
After ALIEN did the haunted house in space so successfully there were a lot of immitators. Then we had a few underwater adventures which did fairly well in a vauge sort of way. Think of this as a cheap way of combining both. Except for Pays and Foster, we have a group of really fine actors working in an underwater mining facility.
Personal note: Seriously, if this had been real and I was Pays' charactor I would have severly hurt the Stern character. His behavior was borish to the point of distracting from the movie and something no decent boss would have allowed.
Anyway, the movie cover said the magic words: GENETIC MUTATION! I was hooked, as always. Pays and Stern are outside doing their job when Stern wanders off (why?) and falls off a cliff. Movie goers probably cheered at that point. Pays goes after him, wandering through fakey looking sea worms and finds the Russian freighter. I liked the scary fish that pops up in Pays' face. Stern shows up with a huge safe, carrying it like it weighs 20 pounds instead of several hundred and they head back.
The safe contains a lot of 'personal effects' from deceased crewmembers which should have triggered a lot more concern than it did. Sterns character slips out a flask of vodka and hides it. Eilbacher's character sees him do it, and later talks him into sharing it with her. Because of the extreme danger of the job, alcohol is not permitted there.
Eventually the Crenna figures out the Russians were doing GENETIC EXPERIMENTATION (I love this stuff) on it's own crew by doctoring their vodka. By the time Crenna comes up with that of course, Stern and Eilbacher are already infected. It hits Stern first, and hardest, then things begin getting out of control.
Up to this point the movie does quite well. It's best effects were, unfortunately, the ones you don't see, using shadow and noise. As good as the cast mostly was, the sets, the production, etc., the special effects were really substandard. Or to put it another way, they were just cheesy and bad, a jarring note to an otherwise interesting movie.
There was not a lot of new material here, nothing terribly original, but it is still not bad. Flawed by it's special effects, surely, but some good acting and a decent script saves it from being a B movie.
