Revealing: 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

Visible crew/equipment: At the bullfight a crew member is reflected in Sands' sunglasses in several shots.

Continuity: 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.
