Continuity mistake: When Lao Che's goons toss Indy onto the cart at Club Obi Wan, note the soles of Indy's shoes are entirely tan with black heels, but when the cart crashes into the bandstand we see the arches of Indy's soles are black and the heels are tan.
Continuity mistake: After Indy and Willie have jumped out the window at Club Obi Wan, when they land on the lower awnings and roll off we can see Willie's high-heels have become flats.
Continuity mistake: After Indy, Willie, and Short Round jump out of the plane with the raft, when the raft finally slows down in the water Willie falls backwards with her legs up in the air and her high-heels have become flats.
Continuity mistake: Right when Indy cuts the bridge and it dangles loose towards the rocky wall, notice that Willie is above Shorty, both in an X position (very likely replaced with dolls). In the close-up of the real actors, both are very close parallel to each other.
Continuity mistake: After Willie crosses the bridge, right when Indy threatens to drop the bag, her hair style changes completely.
Continuity mistake: During the mine race, the cart behind Indy's flips over and is launched far away from the tracks, yet a frame later it's laying down right on the track for a second cart to crash against it.
Continuity mistake: The beginning of the bridge scene is really chaotic: Short walks several meters ahead, the wide angle shows he's alone, then a frame later he's several meters back plus with Willie next to him, then it cuts to him and again he's alone.
Continuity mistake: While hanging from the bridge, when the Thuggee flies down, Indy is sometimes in a higher or lower place, depending on the shot.
Continuity mistake: In the village, the three are surrounded by a huge crowd, yet when Short goes for a walk, half a second later, there's barely a dozen people in front of Indy and Willie. Then it cuts back to the previous wide angle and the huge crowd reappears.
Continuity mistake: When Indy uses his whip to swing into the mine cart that Willie and Shorty are in, the way that he is holding the whip changes from shot to shot. Frontal shots show Indy holding the whip with his hands above his head. In shots from behind, Indy is holding the whip with his hands at his chest.
Continuity mistake: When Mola Ram is trying to get Indy's heart on the hanging bridge, the opening of Indy's shirt keeps changing drastically through shots.
Continuity mistake: The dancers pick up some red handkerchiefs creating a narrow tunnel for Willie to walk through. A frame later they are spread 15 meters apart and just two dancers are parallel to each other holding the fabric.
Continuity mistake: Before Mola Ram hides through a trap door on the floor, his hat is off except for a very brief moment when it's on.
Continuity mistake: The side of the mountain with the bridge is irregular with rough edges when seen in the wide angles, but smooth in the close-ups.
Continuity mistake: Before the water tank falls, there's a shot on Mola Ram and his people next to it. Then there's a wide shot of the tank about to burst and the people running away from the area. Then the previous shot of Mola Ram standing calmly with his men by the tank is repeated, which makes no sense.
Continuity mistake: During the mine cart scene, Indy is sometimes seated on the back, others on the front, with no logic whatsoever, and sometimes between one frame and another.
Continuity mistake: When the rickshaw crashes, the sailor jumps out. One second later, from a different angle, he is inside the rickshaw jumping out again.
Continuity mistake: When Indy is in agony surrounded by candles, the three next to his feet change positions between shots.
Continuity mistake: When the three are leaning on the mountain with the jet of water, Short's arms are spread apart in the wide angle, but close to his body in the immediate close-up, a frame later.
Continuity mistake: When the pilots jump off the plane the flowers on Willie's hair swap positions for a brief moment.
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.
