According to the book "The Films of World War II" by Joe Morella, Edward Z. Epstein and John Griggs, the production was beset by many problems. The book states: "Ann Sheridan parted from husband George Brent; Errol Flynn was indicted for rape; location shooting in a small California town was delayed several weeks because of fog, during which Ruth Gordon and Judith Anderson were besieged with telegrams from Katharine Cornell demanding their return to New York for her stage production of 'The Three Sisters'. Miss Gordon was restrained from leaving, but not before letting it be known that she hated Hollywood and the picture. Fortunately for Warners, the fog lifted, Flynn was acquitted, and the film was completed."
Errol Flynn was criticized for playing heroes in World War II movies. Tony Thomas in his book "Errol Flynn: The Spy Who Never Was" states that Flynn had tried to enlist in every branch of the armed services he could but was rejected as unfit for service on the grounds of his health: he had a heart condition, tuberculosis, malaria and a back problem. He felt he could contribute to America's war effort by appearing in such films as Northern Pursuit (1943); Dive Bomber (1941), Objective, Burma! (1945) and Uncertain Glory (1944). Reportedly, he was at his most professional and co-operative while working on these war pictures. Warner Brothers managed to keep reports about his health problems from being made public because they were afraid it might affect his box-office draw.
Errol Flynn went on trial on charges of rape during production. Warner Brothers studio chief Jack L. Warner rushed his previous film, Gentleman Jim (1942), into release and even hired Flynn a lawyer. He was eventually acquitted of all charges.
Weather problems plagued the production. A thick fog delayed location filming for several weeks in the town of Monterey, CA. Errol Flynn got sick with a sinus illness, a condition that apparently was caused and/or aggravated by the bad weather.
The Minister of St. Olav's Church for Norwegian Seamen, Hans Stesness, acted as a a technical adviser for the religious scenes. St. Olav's is situated in the harbor city of San Pedro, CA, and is now known as the Norwegian Seamen's Church, San Pedro. It is part of the Norwegian Church Abroad. Richard Fraser, playing village Pastor Aalesen, was loaned a robe by Pastor Stessness to wear in this film.
This film was apparently banned in Argentina when it was initially released. The government denied an exhibition permit for the film, stating that the picture could compromise that country's political neutrality.
Location shooting took place in Monterey County and on the Monterey Peninsula in California. Sites included Monterey and Monterey Bay, Cannery Row in New Monterey, Del Monte and the Del Monte Forest and in coves near Cypress Point. Special authorization was granted the production by the US Navy and US Army to shoot in a Restricted Military Zone in Del Monte in the environs of the Monterey Presidio. The "New York Times" reported on Sept. 27, 1942, that the production used a fleet of local fishing boats and two piers at Monterey.
