Continuity mistake: When Jorge is captured there is a shot where he is sitting with his head tipped over to the side, while one of the bad guys suggests to torture him. In the next shot Jorge's head is straight. (01:14:50)
Continuity mistake: In the scenes after Johnny Depp's eyes are removed the length of the blood draining down his face changes from shot to shot. Generally they get longer (as you would expect) but occasionally revert to shorter blood trails. Particularly noticeable when going from under his chin to not reaching his chin. (01:22:05)
Continuity mistake: Towards the end when the alcoholic Mariachi is about to use his guitar case as a RC car, he opens it to get the control and shuts it. A cut to a different shot shows the box open again, but then when it rolls to the truck, it is closed. (01:23:10)
Continuity mistake: Near the end, when blinded agent Sands is shot by one of the two bad guys in the leg, he falls towards and drops both his glasses and the gun he's holding. Then the view changes to the bad guy and in the next shot on Depp, he is holding that gun in his hand again, miraculously. (01:26:05)
Continuity mistake: In the scene at the end of the movie, where El Mariachi steps in to the president's room and saves Jorge FBI by shooting Barillo, it is his right leg making noises when he walks after having shot Barillo, not his left leg as throughout the whole movie. (01:26:35)
Continuity mistake: In the scene where the little boy is guiding Agent Sands to the center of the city, watch Agent Sands' right hand. In one shot, his hand is empty and he is holding on to the wall as he walks, but in the shot where the boy turns around to look at the guy who is following them, you can see a gun in his hand. Shortly after that, his hand is empty again and he reaches in his pants and pulls out the gun.
Continuity mistake: As the bikes are chasing Banderas in the car, you can see the sky is overcast. In a following wide shot of the car and the bikes the sky it is a perfect blue sky with only a few small clouds in the background.
Continuity mistake: When the army shoots the guards around the president, before El shows up and saves him, you can see bullets blowing off pieces of the wall behind. A second later, they disappear. The damage was CGI, and wasn't animated in all the shots.
Chosen answer: They would need to be touching the ground so the electrical current could complete the circuit.
