Continuity mistake: During the shootout with Danny Trejo's men, one of his motorcycle thugs hits a car and is sent flying through the air. If you watch, you can see the approaching car is white, but when the thug runs into the side, it is a green car. (00:53:20)
Factual error: When Antonio Banderas gets shot with the dart in the forehead there are two reasons why that wouldn't work - 1) There isn't any muscle tissue and the skin is too thin for the dart to stick most likely. 2) The tranquilizer would never take effect that quick unless it was injected into a muscle where the blood supply is greater. (00:53:55)
Revealing mistake: When Antonio Banderas jumps into the Cadillac to escape from the bikers, there is a wide shot of him driving the car while being chased for a few seconds where you can very obviously tell he is not driving the car. It is a stunt double, and a very skinny one at that. In fact it almost looks like a woman. (00:55:50)
Continuity mistake: When Carolina is being shot by Marquez she is holding her daughter who actually looks quite serious. When it cuts she is suddenly smiling. (00:56:40)
Continuity mistake: When the mariachi is shot by Marquez we see holes in his shirt made by the bullets as he flies backwards in the air. There's a quick shot back at Marquez still shooting, then back to the mariachi still flying through the air, but this time the holes made by the bullets in his shirt are covered in blood. That much blood wouldn't appear that fast. (00:56:45)
Revealing mistake: After Carolina is shot dead her corpse breathes a little. (00:57:00)
Revealing mistake: When the mariachi wakes up after being tranquilized by the dart, he beats a couple of guys. Then he turns around shooting a guy in his head. If you look closely you can see blood being splattered on his head from the lower right corner. (00:57:40)
Continuity mistake: When Lorenzo practices shooting he hits a bottle which his alcoholic buddy is holding in his hand. Only the neck remains in the hand, but when the camera angle changes the piece is much bigger, including the label. (00:59:15)
Continuity mistake: When Barillo has his face operated on, we get a shot of him where we can see the skin around his eyes is extremely affected by the operation. Then later when we see him looking at his dead daughter, we can see the skin around his eyes is almost fully healed. This is just a few hours after his operation, which would be impossible. (01:05:00 - 01:28:10)
Revealing mistake: You can see Jorge's hair move, as a hair dryer blows in his hair, right before Ajedrez rams her gun in his head. (01:05:05)
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)
Revealing mistake: Near the end of the movie, when Johnny Depp's eyes are removed, he talks with the boy when he's against the wall. In several shots you can see Johnny Depp's eyes through the sunglasses. (01:33:55)
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.
Audio problem: At the beginning of the film when Antonio Banderas is playing the guitar on top of the building and there is a helicopter camera panning around him, he is playing something completely different to what the music does.
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.
Revealing mistake: In the scene where Johnny Depp is searching Cheech Marin by the river, you can see Cheech breathing, even though he is supposedly dead from the gunshot in the scene before.
Suggested correction: There is a feature on the DVD that shows the making of this scene, and that a dummy was used.
Incorrect. What they did was use digital effects to blend the fake eye socket of the dummy onto a shot of the real Cheech Marin because the dummy didn't look real enough in close-up. So, that actually is Cheech Marin, and you can, in fact, see him lightly breathing once or twice. The only part of the dummy you can see in these shots is the area immediately around his right eye, where they blended footage of the dummy in. They specifically said on the DVD that the dummy didn't look real enough to be used on its own. I'm not sure how you could have missed that part on the special feature because they show how they blended the two shots.
