Continuity mistake: When Indy tries to grab the antidote vial from the table, in the closeup just as the vial falls off the table the camera follows the vial as it lands in the empty area to the left of Lao Che's chair where Kao Kan's chair should be, but it's not, and the rug's edge with wood floor beside Lao Che's chair though it shouldn't be. Then Indy hits Kao Kan who is again seated closely to Lao Che's left, as he should be, and when Kao Kan falls backward we see the rug edge is nowhere near Lao Che's chair, also as it should be. (00:08:20)
Visible crew/equipment: After Willie spits in Indy's face it cuts to Short Round running through the mine, and just as Shorty turns his head toward the camera behind him, we can catch a glimpse of something blue which does not belong in this dark dreary environment, at the right side of the screen. There is a tall spotlight and two crew members, one is wearing a solid blue shirt and a cap, and the other a blue/white striped shirt with white pants. (01:21:25)
Visible crew/equipment: During Lao Che's car chase, when Short Round pulls up behind the rickshaw and slams on the accelerator, in the next shot just as the car speeds up, we can see the metal bar at the bottom front of the car leading to underneath the rickshaw, for the stunt. Then when the rickshaw crashes we can see the small third wheel at the base of the rickshaw's seat, allowing it to lean all the way back and roll on the ground for the stunt.
Continuity mistake: The mine cart Willie pushes and then climbs into does not have an actual braking mechanism at the bottom of the braking pole, but after Indy joins Willie and Shorty in the mine cart there's a sudden appearance of a metal braking mechanism, which is attached to the pole and base of the cart, for use during the chase.
Continuity mistake: After Wu Han is shot there's a closeup of the gun in Chen's hand, and as the camera slowly pans up to Chen's face note the carnation is on Chen's right lapel, though in the previous and following shots Chen's boutonnière is on his left lapel. The closeup is a flipped shot.
Visible crew/equipment: While clinging to the hanging bridge, just as Indy tries to grab Mola Ram's foot in the closeup we can see Indy's red harness and the wire cable protruding from his shirt. Then after Mola Ram orders his archers to shoot, when Short Round and Willie are shouting at Indy we can see a bit of Shorty's safety cable protruding from his shirt, and it's seen again after Mola Ram falls onto Indy, when Willie and Shorty are shouting once more.
Factual error: In the scene at the end of the movie on the bridge, the fear of heights is increased by the shots of hungry reptiles waiting below. The reptiles shown are alligators. This is wrong: crocodiles are the animals that live in India, not alligators. (01:45:35)
Revealing 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. (01:48:40)
Continuity mistake: During the mine cart scene, right after Indy strikes the overhead metal bin, the next wideshot of the Thuggee goons is a flipped shot, note the stripe direction on their turbans and their cart's brake has switched sides. Then another shot with a view facing the front of Indy's cart looking back towards the Thuggee cart, note the brake at the front of Indy's cart has switched sides.
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. (01:36:00 - 01:39:30)
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. (00:14:35)
