Crew or equipment visible: Apparatus for simulating the gunshot wound in Richard Crenna's back, called a squib, is quite visible as he runs away from the camera in the China Light courtyard.
Continuity: Upon seeing the boom in the river, the Captain (Richard Crenna) leans forward grabbing the forward handrail. In the next scene, he again leans forward grabbing the forward handrail.
Continuity: At the end in the missionary's courtyard 2 Chinese soldiers are shot at the obelisk. One falls in the right open portion the other falls to the left. The left soldier disappears in subsequent scenes.
Errors made by characters (possibly deliberate errors by the filmmakers): Just before shooting Po-Han with a Springfield rifle to put him out of his misery, Holman makes a long-range adjustment to the rifle's rear sight. Such an adjustment would not have been necessary, since Po-Han was fairly close to Holman.
