The Secret Land (1948) | Atomic Age Cinema – 20th Century Retro Video
This film documents the largest expedition ever undertaken to explore Antarctica. The expedition, code named “Operation High Jump,” was made by the U.S. Navy and involved 13 ships (including one submarine), 23 aircraft, and about 4700 men. It was touted to be an expedition to find “coal deposits” and other valuable resources, but in actuality they were trying to find the underground base of the Nazis in Neuschwabenlandt. The Nazis had done a very detailed study of Antarctic and were alleged to have built an underground base there.
