Corrected entry: The scene on the train features some dialogue implying the assassination of James Garfield, President of the United States, by Charles J. Guiteau. However, the assassination took place in 1881; the film takes place in 1880.
Corrected entry: In the final gun fight Clint Eastwood shoots the deputy in the off yellow shirt standing next to "the fat man" in the upper stomach. The deputy does not seem to notice this and keeps firing. In the next scene he appears to be shot again and falls dead, only one bullet hole is visible. (01:57:34)
Corrected entry: Right after Little Bill beats the tar out of English Bob, Bob falls unconscious. Little Bill then proceeds to yell at everyone standing around. While he is yelling, watch closely in the background (bottom right of the screen) and you will notice the unconscious English Bob moving and looking directly at the camera waiting for a "cut."
Corrected entry: During the final scene, there is a thunderstorm happening as Will rides into town and then proceeds to kill Little Bill and the rest. Although there is very loud thunder, there is never any lightning.
Corrected entry: Eastwood is visiting the grave of his wife. On the gravestone it reads "Born March 1840....died August 1878...aged 29 years." But that would be 38 years.
