The film's working title was The Depths Below. Re-release prints were retitled Submarine. The Devil's Playground was a remake of the 1928 Columbia film Submarine, directed by Frank Capra and starring Jack Holt (see AFI Catalog of Feature Films, 1921-30; F2.5454). The 1931 Columbia film Fifty Fathoms Deep was also based on the same story (see below).
