Corrected entry: In the scene when Tuco has ordered Blondie to stand on a stool and put the hangman's noose around his neck, he orders him to tighten the noose. Just as Tuco aims his pistol to shoot out the leg of the stool, an explosion causes the entire floor to collapse. Tuco drops to a lower level but logically Blondie should have dropped also, thus hanging himself. Instead he mysteriously disappears and lives on for the rest of the movie.
Corrected entry: When Tuco is riding into the three-man bounty hunter ambush, one of the men fires a shot, presumably killing his horse as Tuco is not shot, and if the horse was only startled it would rear back and not tumble forward. The then dead horse is missing from the rest of the scene.
Corrected entry: In the beginning scenes of the movie, Angel Eyes shows up at the man's house to get the name Bill Jackson is hiding under. The boy sits at the table and starts to spoon out some of the food from the bowl but his Mother stops him. He puts the spoon down on the table and leaves. The man then picks up the bowl and the spoon is now back in the bowl.
Corrected entry: Near the end of the film Tuco (Eli Wallach) races around Sad Hill cemetery quickly reading hundreds of tombstones in his rapid search for one marked 'Archie Stanton' - in which he believes is buried two hundred thousand dollars in gold. Yet after having found it Blondie (Clint Eastwood) has to assist him in reading the word 'Unknown' marked on the grave next to that of Stanton. Tuco tries "Unk . . . unk . . ." Strange that an illiterate man had just managed to swiftly read so many names.
Corrected entry: At the beginning, when the Bad shoots the farmer, he falls down on his stomach. When the farmer's wife sees him dead, he's on his back.
