Factual error: Why is Hilts not wearing a uniform? A serving officer captured behind enemy lines in civilian clothing risked being shot as a spy. If a prisoner's uniform was too worn or damaged to wear, it was routine for the German authorities to replace it - a P.O.W. in civilian clothes is an obvious escape risk. He is wearing a pair of tan chinos, a cut off sloppy Joe sweatshirt, both ridiculously anachronistic - Sixties hipster fashions - and nowhere even close to a World War 2 uniform. He is also wearing Army Type III Service boots - something that would never have been issued to a fighter pilot.
Continuity mistake: In the wide-angle shots of the blue Willys (Jeep) wagon, the windshield is a 2-piece version with a vertical divider in the middle. The close-up shots don't have the divider.
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)
Continuity mistake: When they arrive on the island of Talos, the bronze giant, Hercules and Hylus find the statues atop huge plinths. In close up, they are looking up at the statue of Talos, then in a wide shot they start to walk towards it across bare rocks, then in close up they are back where they were with plants behind them.
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: 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.
