Trivia

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 movies as El misterio de las nieves (1943), El escuadrón suicida (1941), Aventuras en Birmania (1945), and Tres dias de vida (1944). Reportedly, he was at his most professional and cooperative while working on these movies. Warner Bros. 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 Bros. studio chief Jack L. Warner rushed his previous movie, El caballero audaz (1942), into release, and even hired Flynn a lawyer. Flynn was eventually acquitted of all charges.

When a character refers to a traitorous Nazi collaborator (like Karen's brother, Johann) he's called a "quisling". This term comes from a Norwegian fascist supporter of Nazi Germany's occupation, Vidkun Quisling, a former army officer who served as a puppet prime minister for the Nazis. He was tried for treason by Norway and executed in 1945 after its liberation.

The Minister of St. Olav's Church for Norwegian Seamen, Hans Stesness, acted as 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 (Pastor Aalesen) was loaned a robe by Pastor Stessness to wear in this movie.
