Visible crew/equipment: In the scene where the Dons are looking at the map of California, Zorro runs in and cuts it down, over all of the men. You can clearly see that strings are pulling it over the men.
Other mistake: Near the end of the film there is a stand-off, if you look in the sky an aeroplane flies by.
Continuity mistake: When Alejandro and Captain Love are fighting on the gold lift, Alejandro punches the sword out of Captain Love's hand. He grabs it and stabs it through him. When it shows the top view of the sword stuck in Captain Love, hit the pause button. Look at the sword blade going through Captain Love's stomach.Then look at the other end of the blade going out of his back. They are at different places in him.
Revealing mistake: In the scene where Captain Love and Antonio Banderas (as Zorro) meet in the hallway of the hacienda, two guards rush down the hallway and drop their rifles and swords. Zorro asks them to bend over and then proceed to kick/nudge them out the window. If you watch carefully, you'll notice that the guard on the right (furthest from Zorro) reacts to the kick too early.
Continuity mistake: Near the beginning of the movie, after the big fight scene, Zorro rides up the steps on his horse and behind him you can see that the sun is setting, which means it should be early evening. But whenever it shows the boys, the light on them and the landscape makes it appear to be mid-day.
Visible crew/equipment: In the ending shots, when Alejandro and Captain Love are fighting, when Captain Love falls down the hill, Alejandro grabs a shovel and slides down the hill. If you look at the shovel, you will see the strap that holds his feet to it.
Continuity mistake: During the Banderas/Zeta Jones fencing sequence, right after he kisses her the first time, we see a shot from behind her and her shoulder is bare. The shots before and after have it covered, with the fabric tight to her so it couldn't slip off. He slices the fabric off in the next shot.
Factual error: During the scene towards the end of the film where Alejandro is chasing Captain Love in the shack with the furnace at the mine, we see a pressure gauge just before the furnace explodes. The unit of measurement on the pressure gauge is shown as kg/cm2. Metric measures were not used in Mexico until eleven years after the film was set, and as California was a part of Mexico at the time, metric measurements would not have been used there.
Continuity mistake: Later in the movie, when Alejandro is now Zorro and in the house confronting Captain Love by drooping in behind him. Watch the tip of the sword as it moves to a different location on the Captain's uniform.
Continuity mistake: Don Rafael's hair keeps changing from being curled to straight when Zorro (Antonio Banderas) first appears before him.
Audio problem: During the scene when Anthony Hopkins is in a dark corner and starts talking to Don Rafael, his lips move at different times than his speech heard on the screen.
Audio problem: At the very beginning where the two young boys cut the eye holes, the sound of cloth ripping is not synchronized with the knife cutting it.
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.
Continuity mistake: When in the cantina, at the time the corn stalks disappear, Zorro knocks the sword out of Alejandro's hand. The sword seems to fly back behind him. In the next shot, Zorro catches the sword because it is now falling straight from the sky.
Visible crew/equipment: In the opening scene when Zorro (Anthony Hopkins) is freeing the peasants and jumps down from the top of the mission to the small balcony, you can see that the bricks where he lands actually either are made of or mounted on some type of rubber as they give way and bounce back under his feet when he lands there.
