Continuity mistake: When Indy drives the Nazi car, he turns the steering wheel to our right, but the car skids to the left. (00:07:10)
Continuity mistake: After the Roman shipwreck, the Spanish flag on the dive boat goes from flapping vividly in the wind in one shot to then hanging limp in the next. This discrepancy is throughout all of the exterior dive boat scenes. This likely shows which clips were filmed on location and which were filmed in a studio. (01:09:40)
Continuity mistake: Within the Roman shipwreck, Indy is grappling with his fear of snakes (eels) with his red flare; a torch light is briefly shone on his head from above. When the shot reverses to the diver at his rescue, she has no torch at all in sight. (01:11:12)
Continuity mistake: While on the boat, Helena does her 7 spades card trick. When she gives Indy a turn, you can see the bottom card is a black 2. When she fans them out, it changes to black king of clubs. Then, in the next shot, it changes to 8 of clubs. (01:16:00 - 01:17:00)
Suggested correction: Not necessarily a mistake. She could be changing those cards by sleight of hand, while moving the 7 of spades into position for the final force. The mistake was not using the 3 of clubs for it.
Continuity mistake: At the start of the film, towards the end of the steam train roof battle, as Indy jumps from the train (200+ feet into the rocky shallow looking part of a river), it's still fairly dark in the early hours of the morning. As he surfaces seconds later, it's considerably brighter. Then, as he walks up the river bank, morning is well broken into much brighter light. Assuming the scene is set around March/April 1945, sunrise in the Alps is unlikely to occur so rapidly. (02:16:01 - 02:16:35)
Continuity mistake: When the villains are following Indy through the caves, the old wooden bridge completely breaks and falls apart. However, when they make their escape across the same bridge, it's intact with only a couple of wooden slats broken.
Continuity mistake: When Indy arrives in Tangier at Hotel Le Atlantique, it is evening. A party is going on in the hotel while the auction is being held. A discussion starts, and a fight breaks out. They go outside, and all of a sudden, it is daytime.
Continuity mistake: Inside the plane, Indy looks at his bleeding wound. Note how shiny and wet it is, as opposed to an instant shot later when it looks dry.
Continuity mistake: The bitten parts of the panini that Helena holds change between shots.
Continuity mistake: When Renaldo is shot in his chest, Helena jolts forward nervously in shock while she grabs a handrail. An instant cut later, she is calmly sitting as if nothing had happened.
Continuity mistake: When Voller grabs the Grafikos tablet from the chest, it's covered in sea snot. When he shows it to Indy, most of the snot is gone. Though a couple of drops dripped while taken out of the chest, the missing amount of moss is really big.This happens in a matter of 2 seconds, before Voller rinses the tablet.
Suggested correction: Watch it again. Voller takes the Grafikos tablet out of the chest, walks to the rear kitchen area, and briefly rinses the sea-gunk off the tablet into a sink. You can hear the sound of a faucet running. Then he shows it to Indy.
Continuity mistake: When Voller grabs the tablet from the chest, he holds its upper left side. A shot later, he is holding its lower left side. When he shows it to Indy, the grip changes again twice.
Continuity mistake: On the boat, when Klaber grabs the wooden chest, he puts his hand on it with his sleeve soaking wet. A shot later, it's dry.
Continuity mistake: When the kid and the sailor are on the boat, watching the sea, the man leans with his hands on the handrail. A shot later, he's leaning on his forearms.
Continuity mistake: When Indy grabs the dial, his thumb surrounds its border, touching the carved words on it. When the shot changes, his hand is suddenly on the left side of the dial.
Continuity mistake: On the boat, when Indy lights up the wax block, it is next to the edge of the table, together with the whiskey bottle, lighter, and cork. Two seconds later, the block is on the center of the table and the rest of the objects are on the opposite side they were.
Continuity mistake: On the boat, when the kid hands Helena the dial, she touches it with her right hand. A shot later, her right hand is away and her left arm is leaning towards the dial.
Continuity mistake: When Indy is hanged, the bomb falls downwards slowly. Check the writing on it, and you'll notice that a shot later, the bomb has moved upwards and is repeating the previous movement.
Continuity mistake: When Indy is hanged, the bomb is stuck parallel to the ground. A shot later, it's perpendicular to the ground.
Continuity mistake: In the tuktuk, Indy tries to snatch the bag from Voller, who grabs it strongly. His left hand changes positions depending on the shot.
