Ah, me - who would have guessed this movie would one day emerge into the light of day after being (apparently) submerged for years in fan-video limbo? This tidbit used to be a staple of the "Late Late Show" circuit - after the parents had gone to bed, the less critically demanding kids would have *their* kind of flick to watch.
Never mind the preposterous assumptions (like huge passenger-carrying atomic submarines cruising under the polar ice cap!). We all tuned in for the weird Theramin-like music and the gooey, drippy one-eyed, tentacled alien. In fact, he looks a LOT like the ones you see on the Halloween episodes of the Simpsons!
Long available only through specialty video outlets (at "special" prices!), this is really an inexpensive trip down memory lane for those of us who first saw it through our fingers in front of our eyes by the flickering light of the boob tube after everyone else had retired. It boasts a "Who's Who" of bit-part and character actors of the genre, some actually effective footage *inside* the underwater UFO, and that totally classic alien. Go on - you KNOW you want to see it! Why ELSE did you look this one up?!?! ;-)
