The Incredible Petrified World is a 1959 science fiction film produced and directed by Jerry Warren, and starring John Carradine and Robert Clarke.

Professor Millard Wyman sends a crew of two men, Paul Whitmore and Craig Randall, and two women, Lauri Talbott and Dale Marshall, down to ocean depths never before explored.

In an interview, star Robert Clarke said that the cinematographer was a well-known Hollywood cameraman who used the pseudonym "Victor Fisher" to avoid trouble with the union for taking a job on a non-union picture.

It remained unreleased for two-and-a-half years until it was put on the bottom of a double feature with another of Warren's films, Teenage Zombies, first showing on November 12, 1959,[1] later released on April 16, 1960.

"[7] The film opens with some stock footage showing a shark battling, and tearing apart, an octopus (perhaps these were the monsters spoken of in the ad line).
