Continuity mistake: After Indy's fight with the Chief Guard on the conveyor belt, when Indy attempts to save him from the rock crusher Indy ends up hoisting himself up in mid-air, and when he reaches the platform Indy's shoes are completely flat, unlike Indy's ankle boots which have heels.Super Grover
Continuity mistake: After Willie saves Short from the hole in the bridge, the river is filled with water. Seconds later, when Indy is about to cut the bridge, there's a wide angle where there's barely any water, with rocks coming out. Then he cuts the bridge and it's filled with water again.Sacha
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.
Other mistake: When fighting the sword wielding guards before getting on the bridge, Indy uses his bullwhip to disarm one of them. As the sword flies out of his hand it kind of hangs in the air as it falls. It is obviously a prop made of a very light material. (01:42:35)
