Baxter Nancy Olson as Nancy Vallon Alan Napier as Sturak Vernon "Red" McQueen as Phil Briggs Gayne Whitman as Dr. Gelster Veda Ann Borg as Madge Robert Keys as Edwin White Sarah Padden as Mrs. Lexiter Production notes The film was shot entirely on location in Hawaii and includes scenes of Pearl Harbor, Molokai, Waikiki, and downtown Honolulu from 30 April to 16 June 1952. Several of the people cast in the film were Honolulu citizens - Honolulu Chief of Police Dan Liu, news reporter Vernon "Red" McQueen, wrestling champion Zinko "Lucky" Simunovich, University of Hawaii professor Joel Trapido, Bishop Kinai Ikuma, Sam "Steamboat" Mokuaki, Charles "Panama" Baptiste, Rennie Brooks, Akira Fukunaza, and Ralph Honda. Also in the cast was Edwin Layton, Admiral Nimitz's Chief of intelligence, who successfully deduced Yamamoto's attack on the island of Midway in June 1942. He later co-wrote the book, "And I Was There: Pearl Harbor and Midway—Breaking the Secrets," New York: William Morrow.(1985) Its world premiere was in Kohio, Hawaii, on 28 August 1952. The film was rushed into release to beat two other John Wayne films, RKO's Jet Pilot, which was not released until 1957, and Republic's The Quiet Man. After the opening credits, a voice-over narrator recites quotes from the short story "The Devil and Daniel Webster" by Stephen Vincent Benet, immediately followed by a voice-over tribute to the HUAC for its pursuit of inquiries "undaunted by the vicious campaign of slander launched against them." A title card at the end of the film states that the incidents in the film were based on the files of the committee, although names and places were changed, and acknowledges the cooperation of the committee in the making of the film. Nancy Olson hated the script, but figured that six weeks in Hawaii and a chance to work with a star like John Wayne seemed good enough reasons to accept. She thought the film would flop and nobody would see it. She was right to a degree – it was not one of Wayne's more successful pictures – but she did not count on how often it would appear on television. She later said people stopped her all the time to mention it. Olson, a staunch liberal Democrat, said Wayne and she would often have political arguments, but she would always let Wayne have the last word. John Wayne recorded an advertisement for Camel cigarettes
