The Incredible Petrified World

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 could not do it and Warren could not find anyone else to do it 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, and as if to add insult to injury, Warren never paid her.

When the characters in the film are trapped under the ocean in the diving bell, they simply leave the bell by climbing up to the hatch, which is supposedly at the top of it. Such an action underwater would immediately flood it, yet not even one drop of water comes into it when they leave.
