Continuity mistake: When they arrive on the island of Talos, the bronze giant, Hercules and Hylus find the statues atop huge plinths.

Continuity mistake: The flight deck of the plane does not exist. It is a made up console that looks nothing like the one on the 747-200 (the plane shown in the air).
Continuity mistake: In the scene where the two men are carrying the coffin with the cross on it down to the crypt, the coffin is being held with the cross pointing towards the last man. But in the next shot the cross is pointing towards the first man, as the coffin has been turned around. Then in the next shot the coffin is in its original position, with the cross pointing towards the last man. There is not enough time for the coffin to rotate this many times between the two men carrying it.
Continuity mistake: When Arthur is out hunting in the woods, Arthur is lying on a tree branch. In one shot, his pants leg is coloured brown, whereas, in the next shot, it is skin colour (as if he isn't wearing any pants). In the next shot, the brown pants leg has returned.
Continuity mistake: Paul Newman and the Count are in the car heading to the rehearsals. When they are about to arrive, the background behind the Count shows a pier, but when the angle changes the background behind Newman shows the car surrounded by buildings.

Continuity mistake: In the scene when Sam and Eric are sleeping by the fire, Sam is on the left side of the screen and Eric is on the right, and Eric has a rip all the way down the back of his shirt. Later, Eric gets up and moves away and calls for Sam to join him. In the shot of Sam moving towards Eric, his back is to the camera and you can see that Sam's shirt now has the rip - not Eric's.

Continuity mistake: When Cleopatra and Caesar meet for the first time, Caesar takes a piece of fruit to his mouth. But in the next shot, his arm is by his side even though there was no time for him to put it down. (00:22:15)
Continuity mistake: When Theo and Eleanor decide to explore the house, before the arrival of Luke and Dr Markway, they are in one of the dark corridors of the house. When Eleanor speaks the leaves of a plant shake, close to her right shoulder, but Eleanor is standing perfectly still, touching the right hand side of her chin with her right hand. Eleanor then hears a gasp, and we hear her thinking. In the next shot of Theo, Eleanor, now in the background, has moved a meter or two away from the plant, she is more to the centre of the archway. The next shot shows Eleanor standing next to the plant again.
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: When PT 109 crashes into the hut at the end of the wharf it is doing about three knots. The shot before (across the stern) shows the wake of a boat doing about 35 knots. When the boat actually hits, a sailor falls over, the wrong way for someone caught by inertia and at the same time, on the port stern bollard, you can see a line fastened and leading ashore. The boat is supposed to be moving alongside the wharf off to starboard: (a) there is nowhere for that line to be fastened to, and (b) the boat is supposed to be still underway.
