Revealing: In the jail scene, Gene Hackman is reading from a book. When he turns the book too far towards the camera you catch a glimpse of his lines on brighter white paper attached inside the book.

Continuity: 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.

Factual error: During the confrontation between Little Bill and English Bob outside the barber shop, all the Deputies cocked their guns - for emphasis. Then Mr. Beauchamp reaches into his bag to show that he only has books, the Deputies cock their guns again. With the rifles they have this would eject the shell that was in the barrel and cycle a new one. It doesn't.

Continuity: In the bar scene where Gene Hackman confronts Clint Eastwood there is a whiskey bottle and a glass on the table in front of Eastwood. He shoves the glass forward and you definitely hear it chink against the bottle. In the next second there are several inches of space between the bottle and the glass.

Revealing: The white horse that Eastwood rides is stallion, not a mare (look carefully).

Continuity: When "The Schofield Kid" kills "Quick Mike" in the outhouse, all of the shots are to the chest. In the cutaway shot of the dead Quick Mike, he has a bullet hole in his forehead.
