Unknown World
Unknown World (a.k.a. Night Without Stars) is a 1951 independently made American black-and-white science fiction adventure film, directed by Terrell O. Morse, and starring Bruce Kellogg, Marilyn Nash, Jim Bannon, and Otto Waldis. Distributed by Lippert Pictures, it was produced by Irving A. Block and Jack Rabin. The film concerns a scientific expedition seeking livable space deep beneath the Earth's surface in the event a nuclear war makes living above ground impossible. Plot Dr. Jeremiah Morley is concerned about an imminent nuclear war. He organizes an expedition of scientists and has them use a large atomic-powered tank-like boring machine, called the Cyclotram, capable of drilling down deep through the Earth's surface in order to find an underground environment where humanity could escape and survive a future nuclear holocaust. The expedition (Andy Ostergaard, Dr. Lindsey, Dr. Bauer, Dr. Paxton, and Dr. Coleman) begins after government funding has fallen through, and they are bailed out at the last minute by private funding from newspaper heir Wright Thompson, who insists on going with them as a lark. Romantic rivalry soon develops between Ostergaard and Thompson for Lindsey, and during the dangerous underground expedition two lives are lost to the perils of their adventure.
