Continuity mistake: Don Rafael's hair keeps changing from being curled to straight when Zorro (Antonio Banderas) first appears before him.
Revealing mistake: In the ending scene when Antonio Banderes is putting the baby to sleep, he steps away to talk to Catherine Zeta-Jones and you can see someone moving the baby back and forth in the crib, to get the baby to laugh.
Continuity mistake: After don Rafael show the other dons the map of an independent California, a close-up shot of Alejandro shows him putting his cane under his arm. The next shot, a wider view, shows him doing it again.
Revealing mistake: During Alejandro and Elena's dance, in the far shots, you can plainly see they are using doubles.
Revealing mistake: When Alejandro cuts off the shoulder of Elena's dress during their sword fight, the dress dips below Elena's nipple, and we can see a pastie covering it.
Suggested correction: I have looked at every frame of the video. I don't see a pastie. At more than one frame, I see her actual breasts and nipples.
Factual error: The film takes place during the 1840s and features an American Army officer, Capt. Love. The western style hat that Love wears with the crossed swords insignia of the infantry was not used by the US Army until the American Civil War, twenty years later. During the time period of the film, US Army officers wore a soft cap with a bill in front.
Factual error: Captain Love's revolver is a Colt Buntline. This model wasn't released until 1876. The movie is set in 1841. He should have been using a Colt Paterson, which was invented in 1836.
Suggested correction: The pistol that Captain Love is using IS the Colt Paterson. You can see this by going to timestamp 1:58:17. If you look at the profile of the weapon in his hand and compare it to pictures of the Colt Paterson, you can see it is a Colt Paterson. The Colt Buntline does not have the same profile.
At the end of the movie Captain Love does have a Colt Paterson, but in the beginning of the movie the pistol he has is a different model. The first pistol looks a lot like a Colt Buntline.
Deliberate mistake: During Alejandro and Elena's duel, he slashes her skirt and reveals her bare leg. When he slashes off her whole gown, she's somehow wearing leggings. Obviously so Catherine Zeta-Jones would not be naked.
Revealing mistake: Stuntmen can be seen in various scenes. Examples include the opening fight at the plaza, the fight at Montero's courtyard, the horse chase scene and the final duel between Montero and Diego.
Continuity mistake: When Three Finger Jack presents Alejandro and Joaquin to the bumbling Mexican soldiers, he touches a wanted poster and asks permission to read it. He's not touching it any more in the next shot.
Continuity mistake: When Love is stabbed, there's no blood on the sword, but later there is. It couldn't have dripped down, since it's only at the end of the sword.
Continuity mistake: When Love is stabbed, the sword isn't sideways, but in the very next shot, it is.
Continuity mistake: When the dons are all in the mine and looking at the large amount of gold while Rafael is laying out his plan to buy the land with the gold that he mined there, you see Antonia Banderas standing among the dons with Love behind and to the left of him. But, moments later, you see him turn his head and look over his shoulder at Antonio, having not been able to move in that short amount of time, having to push through a few of the dons to get there.
