The Navy was initially uncomfortable with both the portrayal of a mentally unbalanced man as the captain of one of its ships and the word "mutiny" in the film's title. After Stanley Roberts' shooting script was completed and approved by the Navy after 15 months of negotiations, the Department agreed to cooperate with Columbia Pictures by providing access to its ships, planes, combat boats, Pearl Harbor, the port of San Francisco, and Naval Station Treasure Island for filming. Dmytryk recalled in his memoir that after "noisy" protests from the Navy subsided, the film production received wholehearted cooperation. This included the conversion of two soon to be decommissioned destroyer/destroyer minesweepers, USS "Thompson" (DD-627/DMS-38) and USS "Doyle" (DD-494/DMS-34/), as facsimiles to portray the USS "Caine".
