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. (01:34:45)
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. (01:27:45)
Continuity mistake: When the girl falls off the elephant, she falls off head first, and during a 5 foot fall, at most, manages to do a complete flip and land on her backside. (00:31:00)
Continuity mistake: When Indy is fighting on the conveyor belt, he is about to be run over a couple of times, but in the next shot he is further away. (01:31:40)
Revealing mistake: During the mine cart scene, after Indy notices that the track cuts out, just as the mine cart flies over the expanse there's a vertical wire at the back of the cart, leading up to the top of the screen, and a horizontal wire at the front of the cart, leading toward the right side of the screen. Additionally, when the mine cart lands on the other track keep your eye on the top edge of the screen as something dips into view, but it's pulled back up immediately, right before the shot cuts away to Mola Ram. The wires and the mysterious object can be seen when viewed on Amazon Prime, but they seem to have been edited out of the DVD (2008 version) I own.
Continuity mistake: During the melee at Club Obi Wan, Lao Che's goons toss Indy onto the dish cart which has a horizontal metal bar between two of its legs over the wheels, but in the closeup as Indy tries to grab the antidote vial, the metal bar has vanished, but it reappears when it crashes into the bandstand.
Continuity mistake: At Club Obi Wan, Indy reminds Lao Che that Kao Kan tried to get Nurhachi without payment, and when Kao Kan raises his hand we see the gauze wrapped around his palm with a strip from his thumb area going diagonally down to his wrist, but in the next shot the gauze strip is wrapped diagonally from the opposite direction.
Continuity mistake: After Short Round snaps Indy out of his trance, when the Thuggee continues to lower Willie we see in her closeup that the flowers in her hair and the flower garland around her neck are already shriveled and blackened, but in her next closeup the flowers are back to being vibrant and fresh.
