Other mistake: Indy's bridge breaks and he is hanging by it with the natives shooting arrows at him. If you look closely you can see two arrows bounce off his back. All the other clatter noisily onto the cliff-face or stick in the bridge, so it's not like they've lost much force due to the range.
Continuity mistake: When Shorty falls through the bridge, a large hole is made. Later on, the hole disappears.
Continuity mistake: Outside the club, a sailor and a girl are in a buggy, which crashes. When the buggy is on the road, the sailor is on one side - when it crashes, he is on the other side, having swapped places with the girl.
Factual error: When they fly from Shanghai (southern China) to India (southwest of China) you see the plane passing the Great Chinese Wall. But the wall is placed in northern China, not on the route Shanghai - Chungking - India.
Continuity mistake: During the 8 minute race on the mine carts through the mine. The group passes several bottomless cliffs, several huge holes, and even a hole of lava about 200 feet long. Yet when the water is released, it gets to them in about 30 seconds, and shows no sign of stopping when they outrun it.
Continuity mistake: All during the fight in the sacrifice temple, the strap across Indy's chest hangs from his left shoulder to his right side. When he hugs Shorty, the strap is reversed. Also, the blood on his mouth occasionally switches sides, as does the parting of his hair. They obviously flipped the negative. Fixed in the DVD version.
Revealing mistake: When Indy and Willie jump out of the Obi Wan Nightclub, they fall through several awnings, the idea being that they will break the characters' fall. All well and good. But, if you look very carefully, you can see small taped-up cut marks which the crew made so the stunt men (and women) could effortlessly glide though the awnings.
Visible crew/equipment: When Indy enters the dungeon, he is using a match to lighten the writing on the wall. You can see the shadow of his whole arm which shouldn't be visible if that match was the light source.
Continuity mistake: When Indy and Willie are waiting for each other to come to their respective rooms, Indy's clock shows the time as 10.17 and yet when the Thuggee guard tries to strangle Indy, the same clock shows the time at 10.36.
Continuity mistake: The scene in the Obi Wan nightclub when Indiana runs out of the window with Willie Scott. Indiana is running behind the gong and we see him collect Willie. In the next shot seen from behind the gong Indiana has yet to reach Willie before they jump out of the window.
Continuity mistake: During the escape from the mine, Indy has to slide along on a rope to catch his companion's cart. Whilst hanging from the rope the shot switches from in front to behind a number of times. Depending on the shot, Indy switches from barely hanging on to having the rope grasped tightly next to him.
Continuity mistake: When Indy is struggling on the bridge, he breaks one or two of the planks. When they are shown again, they are undamaged.
Continuity mistake: When Indy, Shorty and Willie are looking at the ritual from the "balcony" in the cave, they take a look at the big skull on the wall. The artifact stones aren't placed in the skull. In the next shot the stones are there. After a few seconds the camera turns and the stones aren't there again. Some minutes later some of the bad guys bring them and put them in the skull.
Visible crew/equipment: When Indy appears at the entrance of the mining caves to free the enslaved children, he punches out one of the guards and he goes flying in the air and across the gravel. You can see two suspension wires attached to the actor to drag him back through the dirt.
