The Incredible Petrified World

Professor Millard Wyman (John Carradine) sends a crew of two men, Paul Whitmore (Allen Windsor) and Craig Randall (Robert Clarke) and two women Lauri Talbott (Sheila Noonan) and Dale Marshall (Phyllis Coates) down to ocean depths never before explored. But, there’s a technical problem during the launch and the mission is believed lost. Miraculously the crew survives the mishap but they fear that their inevitable deaths are only postponed because they broke free of the cable connecting them to the surface and lost communication.
