Continuity mistake: When Indy is driving the truck, chasing Belloq and his Nazi cohorts, the last Nazi guarding the Ark of the Covenant climbs to the driver's side of the truck and kicks Indy away from the steering wheel. The first time he punches Indy in the arm, Indy's blood is on his fist. However, the second time he punches Indy in the same spot, there is no blood on his fist.
Visible crew/equipment: When Indiana is thrown through the windshield of the truck during the truck chase scene, there is another man in the driver's seat leaning toward the door, driving the truck with dark hair. This is noticeable just as the glass is broken.
Visible crew/equipment: As the bad guys are leaving the dig site for Cairo, there is a shot of the black vehicle (lead car) looking right at the driver. On the bottom of the shot is a shadow of film equipment that shouldn't be there. The shot lingers, so the shadow is very visible. (01:22:50)
Other mistake: In the bar shootout, a man is shot in the head. The bullet hits him in his hat right in the middle of his forehead, and then his hat falls off. But we then see a close-up of his face, and there's no bullet wound in his forehead or anywhere else.
Continuity mistake: In the bar shootout, a man is shot in the head, and as Marion screams in shock she's holding onto the table. In the very next shot her hand is much lower.
Continuity mistake: When chasing Indy in the truck that he has driven into a fruit market, the Germans in their car are surrounded by fruit sellers. One gives a German soldier a melon, who promptly throws it to the ground on the left side of the car. When the car pulls away, the broken melon lies on the right side.
Revealing mistake: As the truck tips to the left, the stunt driver is seen steering, and appears to be activating the ram to finish the stunt.
Continuity mistake: Indy swings on the vine, and his bag is on his hip. As he gets up on the plane, it disappears, but the strap is on his shoulder again in the cockpit.
Continuity mistake: While Indy is chased while running towards the plane, he is in an open field where Jack the pilot can perfectly see him, but when the angle changes Indy is suddenly next to a forest.
Continuity mistake: The huge rock rolls down to ground level, but when the angle changes it's back on a levelled position.
Continuity mistake: The position of the door through which Satipo escapes with the idol is inconsistent in every shot, sometimes it's higher, then almost closed, then back to open.
Continuity mistake: As Marion initiates the drinking challenge with Belloq, from the front she quickly tosses the drink back, tipping her head back then forward. From behind she repeats the motion.
Revealing mistake: When the thug with the blade sticking out his back is standing still, there is some kind of squared device on his back under his clothes, presumably to retract the fake blade to end the sequence.
Audio problem: In Marion's bar, she uses a burning log to knock one of the goons out. As his face changes, you hear "ow!" then he moans as he falls over. However, his mouth doesn't match any of the sounds.
Visible crew/equipment: At the beginning of the ark chase sequence, Indy jumps into a truck off a horse and fights the driver. He pushes the driver up against the door. At the bottom of the frame you can see the camera shadow. (01:23:35)
Continuity mistake: When Indy is shot in the arm in the car, there's no blood on the windscreen at first, but in the very next shot there is.
Audio problem: While Indy tries to escape from the Well of Souls a stick in his mouth falls on Marion, who starts to cry very loudly; however, her mouth doesn't move an inch.
Continuity mistake: After Marion's been thrown in the Well of Souls, a net and pair of sticks over the crate behind Belloq appear or disappear randomly between shots.
Continuity mistake: After the kids save Indy at the bar, he exits and there's a man on the right carrying a load on his shoulder. He appears and disappears randomly depending on the angle.
Continuity mistake: When Indy's crew is lifting the stone door to access the Well of Souls, big clouds of white smoke come out from every corner. A frame later, from a wider angle, they're gone.
