Critic Reviews for The Neptune Factor
Take one toy submarine, add some fishing line to the top of it and have it "explore" your aquarium. This is sadly the extent of the action in this C- movie. It is a huge waste of the talented actors and was an even larger waste of my time in watching it. I have no problem with campy movies, and this was the reason I watched this flick, but Jason and the Argonauts this ain't. Very slow pacing along with the aforementioned "action" scene(s) make this one of the worse films I have watched. Save yourself an hour and a half and clean your house instead, it will be more rewarding and you'll even have a cleaner house to show for your time.
I thought that the combination of Walter Pidgeon and Ernest Borgnine might bely my initial thoughts that this would just be another mediocre TV adventure movie. Sadly not, for thats exactly what it is. A submarine descends to the unknown depths of the ocean to rescue the crew of a lab that has been damaged in an earthquake. I say adventure, but that is really stretching the point: it's a glacially slow moving feature with neither star - nor Ben Gazzara as the vessel's Captain ("Blake") given much in the way of dialogue or activity to work with. It's got some pretty (ropey) underwater photography and a marvellous pre-Disney outing for "Nemo" - only this time he is naughty and enormous. Sorry, one to avoid I'm afraid.
