Continuity: In the scene where Nacho is supposed to beat up the guys on his date with the nun, he's stretching by the wall. He sees two guys coming and jumps over to grab her. When he first grabs her, her left arm is free, but in the close up shot directly afterwards, her arms are both inside his.

Continuity: When Incarnacion breaks up the fight between the children in the schoolyard, Nacho is giving them a lecture. If you watch Chacho's cape tied around his neck, the knot changes from side to middle as they move from shot to shot.

Continuity: In the scene when Jack Black is about to be unmasked and the kids are watching his match on TV, Chancho goes to to cover the TV. He is wearing a pink shirt but in the shot of him covering the TV he is wearing a white singlet.

Deliberate "mistake": Several of the matches Nacho loses, he should actually have won. In Mexican pro wrestling, it is illegal to rip another's mask off, and results in immediate disqualification. This happens twice to Nacho, both in the fight with the midgets and in the final against Ramses.

Continuity: In the scene after Nacho drinks the eagle egg, we see him standing in the wrestling ring with his right arm out holding his cape and his left arm bent. However, when the camera cuts to a closer shot of him, his left arm is suddenly by his side.
