Crash Dive is a typical WWII propaganda film with a stirring musical score by Hugo Friedhofer that prompts any young man to want to enlist in the navy. The cast is uniformly good, especially Tyrone Power as he cleverly tries to woo a reluctant Anne Baxter. Sub skipper Dana Andrews always excelled in military roles. The plot borders on the ridiculous. A German naval base in the north Atlantic- where? An American submarine conducting offensive operations in the Atlantic would likely have been attacked on sight by Allied forces who would naturally assume all subs in the Atlantic were German (such was the fate of one U.S. sub which left New London for the Panama Canal and was never heard from again). Good action scenes for a film of this genre with many of the clichés that would be repeated in other WWII submarine films.
