Visible crew/equipment: During the initial phase of the final assault, a row of men with their backs to the camera is shown. One of these men (right of the center, with a bandaged head) is actually a dummy positioned at the spot where the wall is blasted a few seconds later. (02:29:35)
Visible crew/equipment: When the three Mexican farmers arrive in town you see the traces in the street from a car making a 3-point-turn in the front of the picture. You see the traces in later shots, too. (00:09:15)
