For a Few Dollars More (1965) - 9 mistakes

Other: At the beginning of the film, you see Colonel Mortimer traveling on a train while reading a bible. He has a Indian squaw and a gentleman wearing glasses and a derby sitting across from him. A conductor comes by to pick up their tickets. Colonel Mortimer asks the conductor, "is it far to Tucamcari?" The conductor replies, "we pass there in three to four minutes." The gentleman with glasses starts to tell the Colonel that he is on the wrong train. As he tells him this, look out the train window and see a car driving off into the distance.

Deliberate "mistake": Near the beginning, Col. Mortimer takes down a wanted poster and goes after the man. The man he kills looks nothing like the man pictured on the poster.

Continuity: When Monco drives away with the dead bandits a tail gate of the cart is swinging freely. A few seconds later - after having retrieved the money bag from the tree and driving away 'into the sunset' - the tail gate is not there.

Revealing: After Monco beats up Cavanaugh and places Cavanaugh's back up against the bar, while Monco faces him, three of Cavanaugh's henchmen appear at the entrance of the bar demanding that Cavanaugh be released. Monco turns around and kills all of them with his pistol, while Cavanaugh falls to the floor crawling toward his gun. Monco is walking toward the entrance of the saloon with his back to Cavanaugh. Monco draws his gun and kills Cavanaugh without looking at him. If you look closely at the tip end of the pistol, you can see that the only thing that Monco would have killed was the saloon floor.

Continuity: After Monco brings Sancho Perez back to Indio's hideout, one of Indio's henchmen shoots the tip end of Monco's cigar off. When Monco relights that cigar, the cigar is longer. Immediately after, Indio lights his cigarette with that cigar, and it gets shorter.

Revealing: During the "dream sequence", Indio shoots the young man several times, yet there's neither blood nor bullet holes on his shirt, front or back.

Continuity: Near the beginning when Lee Van Cleef looks at the the wanted poster on the ticket booth at Tucumcari (just after getting off the train), there are two extra zero's drawn onto the poster (as added by the villain). Van Cleef then takes this poster away with him, and slots it under the door of a hotel room on a later scene - notice that the additional zero's have since disappeared from the same poster.

Revealing: While Lee Van Cleef is browsing the news-journal, we first see a front page, followed by 6 identical consequent pairs of pages and then again the same front page from before. Also, the text doesn't seem to be text at all.

Continuity: Monco's and Col. Mortimer's hats are remarkably undamaged after having received six and four bullets respectively. Stetsons are not soft enough to just fly away with the bullet. There should be some holes in them.
