Submarine Command (1951)
Submarine Command is a 1951 film starring William Holden, Don Taylor, Nancy Olson, William Bendix, and Darryl Hickman, directed by John Farrow. The movie is notable for being one of the first to touch on post traumatic stress disorder. After Holden had put $20,000 of his own money into the film it was panned by critics for its brooding melodrama.
