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.
Continuity mistake: In the same part, he is now standing on top of the wall. Zorro takes out his whip and wraps it around the tree limb and swings over to the other part of the wall. When he lands on the wall, he takes off running, letting go of the whip. When the camera returns to him running on the wall, he has a new whip, all rolled up in his hand. (00:08:05)
Other mistake: In the ending shots, when the hoist is bringing up the last of the gold to the wagon, why is the wagon covered up if they still have gold to put in it? (01:52:40)
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.
