The petrified world is a cave deep in the ocean, which is where some explorers end up when their diving bell malfunctions. A movie like this could really use a monster or two. All this one has is John Carradine, who doesn't even act scary in it, and some stock footage of a fight between a shark and a squid. That's better than nothing, I guess.
