Warner Bros. Pictures had produced a financial and critical hit in 1955's
Battle Cry, and was anxious to repeat the success with a film based on Major James Altieri's novel "Darby's Rangers". Altieri was known to Warner Brothers, as he had been
technical advisor on
Force of Arms (1951). Director
William Wellman had established a reputation for turning out top war films with
The Story of G.I. Joe and
Battleground. He agreed to the film on the condition that Warner Brothers finance his dream project,
Lafayette Escadrille, about his experience as a pilot in the famed World War I
French Foreign Legion air squadron. Warner Brothers insisted on emphasizing the romantic pairings of most of the leads to emulate its success doing so in
Battle Cry. A problem arose with the
United States Army. The
United States Marine Corps had enthusiastically lent bases, Marine extras, and film of its campaigns to Hollywood films to
boost its public image. While the Army had as well, it was not so keen on this project, reflecting its feeling that Ranger operations had led to heavy losses of excellent soldiers it thought would have been better employed leading regular infantry units. By the 1950s, rather than the separate Ranger units shown in the movie, the Army preferred training individual officers and
NCOs at the
Ranger School, who then returned to their units and trained them in Ranger tactics and military values. Thus, the U.S. Army's co-operation was limited to training the actors and providing black-and-white stock footage.
Tab Hunter says Wellman offered him the lead role, the director hoping to reunite the stars of
Lafayette Escadrille (
Etchika Choureau would co star and the director's son
William Wellman Jr. also appeared in both films) but Hunter was tired of war films and turned him down. He was replaced by
Edd Byrnes. Originally,
Charlton Heston was cast as
William O. Darby. He was enthusiastic about portraying a recent historical figure; he could interview people who knew Darby in creating his characterization. However, he asked for five percent of the profits.
Jack L. Warner thought he was joking, until just before filming. (Heston later sued Warner Bros for $250,000 – $100,000 fee, $50,000 further earnings, and $100,000 damage to his career.) Warner looked to his studio's contracted actors and chose thirty-year-old
Korean War veteran
James Garner, already slated to appear in a featured part. He had the proper appearance and age to play Darby, who was killed in battle at age thirty-four. It was his first leading film role. His place in the film was taken by
Stuart Whitman. (Garner too would later sue Warner Brothers). Garner later wrote in his memoirs that he did not feel Wellman "wanted me in the part... and I don't blame him: I was too young for it and he deserved a bigger star. But we got along fine because we respected each other." By extensively using original World War II film footage and
black and white cinematography, ''Darby's Rangers'' was able to be filmed economically on the studio
backlot. ==Promotion==
