Although Raye claimed that the 1991 picture was plagiarized from an autobiographical outline she had written, her case was dismissed.) According to information in the Twentieth Century-Fox Records of the Legal Department, Landis and Edwin Seaver wrote a book about her travels while the film was in pre-production at the studio. Although UCLA Arts—Special Collections Library, Landis's material was not used in the screenplay, the studio agreed to let her use the film's title as her book title for the publicity value. Her book, which was published in 1944, first appeared as a serial in SEP (18 December 1943 – 15 January 1944). The legal records indicate that, while the film was based on the experiences of all four performers, only Mayfair and Francis directly contributed to the screenplay. The legal records also indicate that Mayfair's agent, Lou Irwin, was the first person to suggest the idea of the film to the studio. Studio records reveal that Waldo Salt worked on an early draft of the film's script, but the extent of his contribution to the completed picture has not been determined. According to a "The Hollywood Reporter" news item, Islin Auster was originally scheduled to produce the picture. The Twentieth Century-Fox Produced Scripts Collection, also kept at UCLA, contains conference notes with studio production chief Darryl F. Zanuck, who planned for John Sutton to play "Capt. Lloyd." Zanuck told director William A. Seiter, "Martha Raye usually talks too fast and too loud. Try to make her play Martha-Raye-off-stage and not Martha-Raye-on-the-screen, if possible." An August 1943 "HR" news item noted that Jack Oakie had been set for the comedy lead and that Cornel Wilde was being considered for "the juvenile spot." Although a 21 October 1943 "HR" news item stated that Raye would sing "Jeep, Jeep, Listen to the Soldiers Sing," which she had written herself, the song does not appear in the completed picture. This marked the screen debut of singer Dick Haymes. Dance director Don Loper was borrowed from MGM for the production, which was Francis's first film appearance since the 1942 Universal production "Between Us Girls". Mayfair had not appeared in a feature film since the 1930 musical "Paramount on Parade", and "Four Jills in a Jeep" was her last screen appearance. According to an April 1943 "HR" news item, Landis, Raye, and Mayfair were also scheduled to make a short film recreating their act.
