In the original novel the lead character Major Henri de Beaujolais is an officer of spahis (Algerian colonial cavalry of the French Army) and has no connection with the better known Foreign Legion. In all surviving stills of Beau Sabreur Gary Cooper is shown wearing the distinctive spahi uniform and it is not clear whether the lost film was intended to be a Foreign Legion epic.
Plot
A desert-bound member of the French Foreign Legion exposes a betrayer to the Legion. He is then sent on a mission among the Arabs to conclude the signing of a crucial peace treaty.[1]
The sound version of the film featured a theme song entitled "Desert Stars" which was composed by Edward Lockton and Frank Tours. A second song, "Thinking of You," by Joseph Grey (words) and Allie Moore (music), was also featured on the soundtrack.
