Continuity mistake: During the middle of the bar fight scene, Indy was slammed on the counter and whispered to the girl, "Whisky". In the next shot she grabbed the bottle and handed it to Jones. The very next shot she hands him the bottle again. It happens very quick. Watch carefully. (00:32:05)
Continuity mistake: When Belloq grabs the machine gun, his left hand is on the trigger and his right hand on the gun cartridge as he turns round with his back to the camera, but in the next shot, his right hand is on the trigger and his left hand on the cartridge but in the next shot, his hands have changed position once more, this time left hand on the trigger and right hand on the cartridge. (01:42:55)
Continuity mistake: When Indy is chasing after the truck on horseback, he jumps off the horse and onto the truck, as he does this the horse begins to slow down and fall behind, but as Indy throws the German soldier in the passenger seat out of the truck the horse has disappeared, it could not have been hidden from view behind the truck, because the horse's shadow would have been visible. (01:23:30)
Audio problem: At the beginning of the film, one of the guides goes to shoot Indy with a gun, but as Indy uses the whip to defend himself, the gun bounces off a rock and goes into the water. As the gun hits the rock you hear the sound of the gun firing, but there is no sign of a flash from the barrel or any gun smoke. (00:03:10)
Revealing mistake: When the German staff car comes into the market place to find no truck, watch as Dietrich hurls the melon - the SS guy in the front is obviously a dummy for this one shot. (01:29:40)
Continuity mistake: Several times during the fight in and around the truck the bars around the top of the cab come off and are miraculously back on again. (01:24:05)
Revealing mistake: When Indy is running through the cave and finds the spy that took the artifact with spikes through him, he brushes up against the dummy and it shakes like rubber and the light bounces off it like rubber. (00:09:10)
Continuity mistake: At the beginning of the film, When Indy uses the whip to take the guides gun away, Satipo makes a weird face and starts to move away in amazement. The very next frame, in a wider shot, he is not finishing his movements, but on the contrary he is standing still, with a normal gesture, until a second later he starts to repeat the movement and looks from before.
Continuity mistake: When Indy is fighting the Nazis on the truck, one Nazi is thrown from the truck and is rolling the opposite direction of the truck. (01:23:30)
Revealing mistake: When Indy fights the driver of the Nazi truck, the windshield is smashed when Indy is thrown through it, but there is no wind. Look at the driver's hair, not one stirs from a breeze while driving a fast moving truck with no windshield? (01:27:30)
Factual error: The interior of the German U-boat is completely different from the real interior of a Type VII U-boat, which is correctly shown in movies like 'Das Boot' or 'U-571'. For example, the ladder from the conning tower faces a different direction, the map table is too big and on the wrong side, the valves for submerging are on the side of the control room and not at its front and stern, depth gauges are too big...etc. All interiors were standardized, so it could not have been an individual build.
