Character mistake: At the confederate prison camp after they are captured a soldier comes up to the sergeant (Van Cleef) and informs him that the "Captain" wants to see him right away. In the next shot with Van Cleef where he is talking to the commanding officer you will see that he is not a captain but a major. (01:35:00 - 01:35:29)
The Good, the Bad and the Ugly (1966)
1 character mistake - chronological order
Directed by: Sergio Leone
Starring: Clint Eastwood, Eli Wallach, Lee Van Cleef
Other mistake: In the very last scene of the movie, and just before Blondie shoots the rope that is holding Tuco on the grave's cross. You can see a car moving in the background, screen right of Tuco's head. (02:55:29)

Suggested correction: I've just watched this scene; there's no car visible. There's a bit where Blondie prepares his gun prior to aiming, then the camera switches back to Tuco. To the right of Tuco, in the background, a blurry something can be seen for maybe a second moving right to left. The object is far too blurry to identify. There's no reason to believe it's a car. It makes more sense that it's a horse-drawn wagon.
Tuco: I'll kill you.
Man With No Name: If you do that... You'll always be poor... Just like the greasy rat you are.
Trivia: Eli Wallach actually did get a black eye during his torture scene (but thankfully nothing more).
Question: If Tuco seriously thought that The Man with No Name would shoot him, why did Tuco voluntarily stick his head in the noose? Death is death. Why choose hanging over gunshot?
