Other mistake: In the spike room, you see Shorty step on the switch that seals the two doorways. During that part, you see the stone extend from the wall, which he leans against to start the lowering ceiling. However, when Willie enters, without stepping on the switch, she pushes the stone to both seal the doors, start the ceiling lowering again, and extend the spikes. Why did it come out without anyone stepping on the switch beforehand like it did previously?
Other mistake: When Willie is given the pot of soup, she puts her spoon in and the eyes float up to the surface. Why are all of the eyes looking straight upward? Unless they're anchored in some way, not all of the pupils, if any, should be on top.
Continuity mistake: When Willie walks out of her bedroom while Indy is fighting the assassin, the left sleeve on her pyjamas changes from rolled down to rolled up between shots.
Revealing mistake: When Indy is put inside a cage Short Round comes to hug him. There's a shot of Indy from behind and he is a noticeable stand-in: Thinner face, clean hair, no sweat, and clean shaven instead of stubble.
Continuity mistake: After the man is burnt in the lava pit, Indy says the word 'diamonds'. Willy comes closer and then turns her head to the right. When the shot changes she's facing straight.
Continuity mistake: In the mine cart, after Willie cries "Hurry" there's an aerial shot of the cart and Short Round has vanished.
Continuity mistake: When Indy is stopping the mine cart with his foot Willie's hand is on top of Indy's or not depending on the shot. This swaps back and forth.
Continuity mistake: When Indy falls inside the mine cart, the protruding log disappears. A shot later it reappears, but when Indy hits the railroad switch with the shovel it disappears again.
Continuity mistake: When Indy is fighting the Chief Guard on the conveyor belt, there is nothing behind the guard before he picks up the large rock, but in a close-up there are now small rocks on the belt.
Revealing mistake: When Indy is whipped six times, the first time we can see the whip doesn't touch him, or go anywhere near him.
Continuity mistake: When Indy hangs the assassin on the fan, in one shot he's spinning, but in the very next shot he's not. He can't just instantly stop, he'd have to slow down.
Revealing mistake: When Indy wraps his whip around an assassin's neck and hangs him on the fan, we can see it's not actually around his neck, it's just attached to his clothing.
Continuity mistake: When Indy punches Short Round, he starts falling forwards, but lands on his back.
Audio problem: Indie lifts Willie from the lava pit, she is semi unconscious. She slaps him weakly but instead a loud and strong punch is heard.
Continuity mistake: Before the first sacrifice victim is being lowered into the lava pit, Mola Ram is standing on the edge of the pit, but in a few shots later he moves some feet away.
Continuity mistake: When Indy, Willie and the kid are leaving the village riding the elephants the sun changes between shots.
Continuity mistake: On the ladder, when Mola Ram tries to grab Indy's heart, Mola's hands and Indy's chest are very sweaty and dirty in the close-ups, but dry and quite clean in the wide angles.
Continuity mistake: On the bridge, when Indy threatens the Thugees to drop the bag, they're a couple meters away from his back, but in the next angle they're further away.
Continuity mistake: After Short Round breaks the Maharaja's spell, the blood on the side of his mouth swaps from a thick strand to a thin one between shots.
Continuity mistake: Mola Ram falls off the bridge-ladder when a step breaks in two, but from the immediate wide angle it just moves slightly out of place. Furthermore, in the next angles the step is perfectly fixed.
Chosen answer: His neck was snapped by the whip getting caught in the fan. There isn't always blood with a hanging. Since the fan wasn't designed to hold a man's weight, the motor in it would have stopped or given out.
