Four adventurers descend to the depths of the ocean when the cable on their underwater diving bell snaps. The rest of their expedition, believing them to be lost, abandons hope of finding them. Exiting the diving bell, the party finds themselves in a network of underwater caverns. They encounter a shipwreck survivor. He tells them he has been there for 14 years and that there is no way out. The two men in the exploring party believe him only after a hike to a volcanic vent that supplies the caverns with oxygen. On the surface, Prof. Millard Wyman, the elder scientist who designed the original diving bell, decides to try again to explore the depths of the ocean. He finds out that there is another diving bell in existence that is identical to the one that was lost... Written by Jim Cobb <gymcobb@azstarnet.com>

When the characters are trapped undersea in the diving bell, they simply leave by climbing up to a hatch, supposedly at the top of the bell. Such an action underwater would immediately flood the bell. Yet, not even a drop of water enters the bell when they exit. See more »

The most exciting thing about the film is the title ...
17 October 2004 | by FranklinTVSee all my reviews

When thinking of a catchy film title, "The Incredible Petrified World" is a strange one, as by the third word, you are starting to think of frozen stillness becoming lifeless. So, in this case, it is an apt title.

The simple problem with this film is nothing happens; and it seems forever to occur.

Our four heroes (sorry, two heroes and two women, judging by the subservient roles given to the female leads, and the bleak plot warning that if you step out of line, men will hate and leave you) go down in a dodgy diving bell, which conveniently fails at depth near an underwater cave that glows in the dark (phosphorus they explain). I could be critical of the science at this point, but this claim pales with the completely unexplained manner they can snorkel in and out of the diving bell without it being flooded.

Anyway, once they reach the Incredible Petrified World (aka small cave with glowing walls), they eventually meet a stranger who claims he got there from a shipwreck 14yrs ago. Now, it would have been good if they explained how he might have been able to swim so deep without being scuba supported, although it would have been better to explain why they chose to make him look like Chico Marx with a Santa beard, and wearing caveman clothes.

And thats the main problem; you don't mind putting up with the first three quarters being tedious if there is a payoff. Alas, in this case, the payoff is just the remaining tedious quarter.
