One of the hanged men is plainly breathing (albeit shallowly) in the foreground to the viewer's right, as the Stranger is washing up (after shooting Oaks) in the background.

After a captive sacrifices himself to stampede Oaks's posse's horses over a hill, leaving them without escape, Once they've shot the captives, suddenly the horses reappear, back for their getaway.

During the lynching of Oaks' gang, the tire tracks of the camera car are clearly visible down the middle of the main street.

A cartridge or round includes the bullet, case, and primer. At 13 minutes two Indians melt gold to make and gift The Stranger "with gold made bullets." The gold bullets are obviously cartridges spray painted gold.
