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>

Did You Know?


Phyllis Coates accepted the role of Dale Marshall as a favor to director Jerry Warren, who was a former boyfriend; the actress originally cast in the lead couldn't do it and Warren couldn't find anyone else in time. He convinced Coates to do it by telling her that the film would not be shown in California. However, after it was completed, she found out that Warren did indeed release the film in California, and she was told by at least one studio executive (at Columbia) that the film was so inferior and shoddy that the studio would not be hiring her again. On top of that, Warren never paid her. See more »


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 »


[first lines]
Narrator: This is the sea, as old as the world itself. It extends over three quarters of the surface of the globe. The sea: the birthplace of life, the great storehouse of minerals, the prison of haunting mysteries.

Unusual, unexpected, but still not very good '50s sci-fi
11 March 2007 | by mstomasoSee all my reviews

Like The Mole People, Unknown World and The Abyss, The Incredible Petrified World (IPW) defies sci-fi conventions by taking place entirely in inner space. Also like Mole People and Unknown World, inner space seems to have been built for human habitation - not only are the cave networks the perfect size for humans to walk upright in, the absurd Cyclotram of the unknown world even has a nicely graded (though bumpy) road to travel along while drilling through solid bedrock.

The only resemblance between this film and The Abyss is the underwater setting. IPW was made with less than a fraction of The Abyss' budget and the most talented actress in the film (Coates) was not paid. The film proceeds with mostly character-actors, and little to no character development.

Four people - a professional diver, two oceanographers and the stereotype female reporter - man the first deep-sea submersible diving bell (ya, this technology was already somewhat obsolete by the 1950s and the Navy was doing far more interesting things but who cares) on its first exploratory mission. Predictably, something goes wrong. But soon enough the crew finds itself in an underwater maze of caverns complete with fish ponds, potable water, a monitor lizard and a vaguely menacing hermit with extremely bad hair.

Putting all the absurdities aside (which is asking a lot), the plot is at least different and does take a few unanticipated turns. The terrestrial portion of the plot - focusing on Carradine as the philanthropic engineer sponsoring all of this - is actually more or less believable and interesting. But any value this plot adds is easily balanced by the laughable goings-on down below - especially the unnecessary and ridiculous hermit subplot.

All in all, I think this film deserves a better rating than it has here on IMDb, but I was seriously reconsidering my rating after I read about Ms. Coates' difficulties resulting from this film.

Recommended for B-sci-fi fans. AAAC (avoid at all costs) for everybody else.
