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.

Correction: After the shot, and during the close up of Tuco on the ground is shown, the horse can be heard galloping away.
