Audio problem: At the beginning of the film, one of the guides goes to shoot Indy with a gun, but as Indy uses the whip to defend himself, the gun bounces off a rock and goes into the water. As the gun hits the rock you hear the sound of the gun firing, but there is no sign of a flash from the barrel or any gun smoke. (00:03:10)
Continuity mistake: When Indy and the Peruvian are entering the cave and clearing the cobwebs, you can see at least one spider on Indy's back. The next shot shows a clear, long shot of Indy's back with light reflecting on his jacket and no spiders. In the next shot, the Peruvian notices the spiders. (00:04:20)
Continuity mistake: As Indy and Satipo enter the temple, When Indy says to Satipo "stop" he is holding the whip in his right hand, yet when Indy says "stay out of the light" the whip is in his left hand. (00:05:10)
Continuity mistake: In front of the idol, Indy shows Satipo the trap on the floor. Satipo's head position is different in all 3 shots in barely 2 seconds: First he's looking downwards, then straight, then his head is turned sideways, and then back to straight. (00:08:20)
Continuity mistake: In the beginning, Indy's partner takes the idol, throws down the whip, and leaves him hanging on a ledge with the ceiling closing down to the ground. While he is hanging the you can see that the ceiling barely has enough room for Indy to fit. Indy struggles to get up which during this time he would have no room to get under, yet when he finally gets up the ceiling has risen giving him plenty of room to get under. (00:08:45)
Revealing mistake: When Indy is running through the cave and finds the spy that took the artifact with spikes through him, he brushes up against the dummy and it shakes like rubber and the light bounces off it like rubber. (00:09:10)
Continuity mistake: Near the beginning of the movie where Indiana is running away from the tribe of South American Indians after Belloq robs Indiana of the gold statue, in one shot you can see that the Indians are only a few meters behind Indiana, but in the next shot, they are at least 50 meters behind. (00:11:20)
Continuity mistake: There's a shot of the plane at the beginning, taken from the front, looking down the length of the body, where there's no writing on the side. (00:11:45)
Suggested correction: On a good quality frame the number is visible quite clear. Not visible on a poor resolution frame.
Continuity mistake: When Indy climbs onto the pontoon of the airplane from the lagoon in the opening sequence, he is obviously wet from swimming in the lagoon. However, in the next scene as he climbs further, his clothes are miraculously dry as observed by watching them blowing freely during take-off. (00:12:05)
Factual error: At the beginning of the movie, Indy escapes in biplane with registration OB-CPO (a Star Wars nod, as noted in trivia). However the OB registration is used by Peru, and it should be followed by four digits, not by three letters. (00:12:10)
Continuity mistake: On the blackboard, between the numbers 4 and 5, the word "and" is written. After the girl shows the "Love you", the word is replaced by a dot. (00:13:49)
Continuity mistake: In Indy's class at the beginning, the girl that lowers her eye lids to show the phrase "Love you", is looking in a totally different direction than the people behind her. They're all supposed to be looking at him, but the girls behind her are looking to their right while she is looking straight. They can't be daydreaming because they're all smiling and look infatuated. (00:13:58)
Continuity mistake: When the government comes to see Indy at the University he is teaching, they enter the large room, I think it's a gymnasium. He puts the huge book on the table and one of the buckles comes undone. But when he goes to open the book to show the g-men a picture of the Ark he undoes both buckles. (00:15:30 - 00:19:30)
Continuity mistake: When Indy is listening to the one Army agent he is in the process of putting his right hand into his pocket. In the next shot the hand is back on the leather case. (00:16:46)
Continuity mistake: Major Eaton's right hand moves from his ear to his mouth between shots. (00:17:34)
Continuity mistake: During the scene where Indy and Marcus are with the Army intelligence agents, watch the agent who is wearing the light blue suit - at the moment when Marcus refers to a secret chamber, the agent in the blue suit has his right hand resting on top the chair that he is sitting on, but in the next shot when he replies "secret chamber" his right hand is now on his face. (00:17:55)
Continuity mistake: Eaton and Musgrove are sitting, waiting for Indy to open the book. When Indy opens it, suddenly Musgrove is standing. (00:19:43)
Continuity mistake: When Indy is packing his suitcase to go to Nepal, he picks up a gun that is wrapped in a piece of cloth, he tosses the gun with his left hand into his right hand and begins to unwrap the gun from the cloth by raising his right hand, so that the gun will fall into his left hand, but the gun ends up falling into Indy's right hand instead of his left hand. (00:22:10)
Factual error: When Indy flies to Nepal, there is a scene of the sea plane taking off with the Golden Gate Bridge in the background. The movie is set in 1936, and the bridge wasn't completed until 1937, with pictures from December 1936 showing large gaps still in the deck that do not appear in the movie. (00:23:00)
Factual error: During the travel to Nepal, "Thailand" is written on the map. The country has had this name only since 1939. This film takes place in 1936, when Thailand was called Siam. (00:23:20)
