Trivia

Once, when director John Ford called Loretta Young to the set, the actress refused to leave her trailer until she was happy with her hair. After waiting for her for a while, Ford and several grips went to her trailer and began shaking and rocking it until she came out.

The line "I knew a man named Trubshawe..." refers to a lifelong friend of David Niven's, a source of references or character names in several of his films.

Director John Ford, in an interview published in a modern source, stated "I just didn't like the story, or anything about it, so it was a job of work."

Ford was apt to amuse himself on the set by pulling pranks on his players. He found a convenient victim in the person of British actor David Niven. After telling Niven to enjoy himself and get drunk that night, the next day Ford had him rehearse a scene in front of the film's producer Darryl F. Zanuck which involved a stethoscope and a wound dressing. In Niven's own words: "... I put my hand in the pocket for the stethoscope and pulled out a large snake. Trying manfully to continue the scene, I dropped it on the floor and opened the first-aid box. When I saw it was full of little green turtles, I let out a yell and flung it in the air." Ford called, "Print it!" and the gag blooper was a long-time favorite in the studio's projection room.

German Lugers do not have the maker's name nor serial number on the left side of the upper frame. The serial number is on the front of the frame and the maker's name is on the top of the receiver. Lugers were made in the hundreds of thousands, and trying to trace the origin of the pistol is nearly impossible.

In 1948, Twentieth Century-Fox released another film based on the same source, entitled Massacre à Furnace Creek (1948), which was directed by H. Bruce Humberstone and starred Victor Mature.
