Visible crew/equipment: When the guitarist almost gets hit by a bus, you see a shot from inside the bus about what happens outside. If you watch carefully you can see Robert Rodriguez in the rear view mirror holding the camera with a towel on his head.

Revealing: When Azul is in the bar and goes into the men's room to execute the man inside, we look straight at the men's room door. You hear a gun shot, but you can see you can see a flash reflected. That means that what ever made the gunshot sound was behind the camera. Also in the same shot you can see a man's shadow on the door.

Revealing: In the scene where El Mariachi is trying to escape Moco's men by sliding down a wire onto the bus, he first throws the ball-and-chain-weapon over the wire. But then when he slides down, you can see a pulley device that he is using, not the chain.

Visible crew/equipment: In the last scene of the movie, when El Mariachi is with his bike, just as the camera pans up the shadow of the camera is visible on him.

Continuity: After Moco and Azul finish their telephone conversation about how many of Moco's men Azul killed, Azul leaves, but one of Azul's men goes back to see Azul's women. In the background, there are posters of the Playboy bunny logo and a woman on a jetski. Ashe runs away from the lethal women, the posters are nowhere to be found next to the doorway.

Continuity: When Azul is in the bar, just after killing the men at the table and the barkeeper he puts his machine gun back in his case leaning against one side and picks up a sawn-off shot gun. When he comes back from the toilet, the gun is back in the case and not visible anymore.

Continuity: When the mariachi is being chased, after they've left the hotel, he runs up a truck and two of the bad guys shoot each other trying to hit him. He picks up a gun to shoot at the other bad guy. The gun he actually fires is a completely different type of gun. When he drops it, it's changed back to the one he picked up.
