Character mistake: On the day Rebecca arrives home, Junior Douglas says that he was "Valedictorian, Class of '95." Earlier, Drago talked of almost killing Running Buffalo "during that trouble back in the '40's," which would have been about 50 years earlier. That would mean Drago and McLintock were fighting Indians when they were babies, or possibly before they were born!
Continuity mistake: A blond boy in a light brown shirt is attacked by a crow and goes from having no blood on his neck to having a lot of blood smeared on his neck between shots. (01:14:10)
Visible crew/equipment: When James Bond shoots down the helicopter, then it crashes. He emerges from the rocks to run from the crash site to the right of the picture, just as you see Sean Connery emerge from behind rocks from the right in the same scene. So, for about a second, there are two James Bonds in the picture. One is the stuntman, and the other is Sean Connery. (01:38:05)
Factual error: The Forum shown in that film is smaller than in real life. Also, Cleopatra is shown passing through the Arc of Contantine, a monument that was built centuries after her death.
Continuity mistake: When Princess Dala is drunk on the tiger rug, her champagne glass jumps from her right hand to her left just after she says "tally ho .... no more virgin queen".
Audio problem: When Sarge is giving instructions to Allbright over the taxi radio Allbright replies "I don't know what the union's going to say about all this" to which Sarge replies "**** the union". His mouth doesn't open while the noise sounds to cover up his swear word.
Revealing mistake: After a carriage rolls over Midshipman Poop-Decker's sword, he can be seen pushing some kind of trigger with his thumb to make the sword split in two. (00:05:05)
Continuity mistake: When James Coburn is about to leave the phone booth where he's been lighting matches, the number of matches he leaves on the top of the phone changes between shots.
Continuity mistake: When Donovan is picking Miss Deddum off the ship, she loses her balance (and bag) and there are many outriggers near the ship. First the water is choppy, then Donovan says "watch these swells." The next second it's calm as glass when she steps off and he pulls her in the water. The next scene, everyone is jumping from the ship and suddenly, all the outriggers are nowhere to be seen near the boat.
Continuity mistake: When Dr. Boyer's car is pulled out of the pool, it is facing in the opposite direction from when it was driven in.
Continuity mistake: In Irma's apartment, the windows are covered with newspapers, to block out prying eyes. From the apartment's view, the newspapers don't cover the lower third, but from the street view, the lower third is covered.
Factual error: Anthropology Professor Robert Orwell Sutwell explains that his black kimono was a gift from "the Tokyo Fire Department." The seven characters embroidered on the kimono are Chinese, not Japanese.
Continuity mistake: When John Davis is approached at the beginning of the movie, he is sitting at a bar table. Depending on the camera angle, he is resting his cheek against a closed fist or his thumb. (00:04:00)
Continuity mistake: Goliath's two new friends grab him by the arms and carry him between the horses to escape from the guards; as the bad guys give chase, there's no consistency between shots regarding the shadows; they gallop through shadow areas that are entirely exposed to the sun when the baddies are coming, and vice versa.
