The film was directed by John Ford, who also directed "The World Moves On" and "Judge Priest" in the year it came out. Ford co-produced the film along with Merian C. Cooper and Cliff Reid. Cooper himself had a military career. He served in the United States Army Air Service from 1916 to 1921, and would return to military service in World War II, in which he served from 1941 to 1945, reaching the rank of brigadier general. Ford himself served in the United States Navy in World War II from 1942 to 1945, reaching the rank of commander. He stayed in the reserves from 1946 to 1962. In the reserves, Ford reached the rank of rear admiral. The script was written by Dudley Nichols and Garrett Fort, based on the 1927 war novel "Patrol", by Philip MacDonald. The novel was first adapted in 1929, by Walter Summers, who directed and wrote the film with Victor McLaglen’s younger brother Cyril in the lead role. The novel and movies focus on the psychological strain on a patrol of British soldiers when they become lost in the desert and surrounded by the enemy in Iraq. MacDonald himself served in the British cavalry during World War I in the Mesopotamian campaign.
