Factual error: In the scene where they are flying to Peru from US, they fly over a "map" of a Central America region and the country of Belize is shown. That country was the British Honduras until 1973. It was then renamed to Belize.

Continuity: In the opening scene with the drag race, the lead car in the caravan speeds ahead in response to the challenge. In the next scene, the caravan turns right and the challenger continues straight. At this point, the entire caravan is together despite the fact that the lead car would have been far ahead by that point.

Continuity: When Mutt slams his fist on the table in the Diner the Ketchup and Mustard bottles fall over, the shot pans to Indiana's back and the bottles are standing up again, he tells Mutt to sit down, the camera pans back to Mutts back and the bottles are as they were after Mutt slammed the table and Indiana picks them both up.

Continuity: After the duel between Mutt and Irina Spalko, Mutt falls down into the car with Indy and says, "She is getting away!" as she is seen driving away. However,in the following shot when they are driving near the edge Irina comes out behind them.

Factual error: The hotrod in the opening chase scene has a Chevrolet engine in it, even though it is a Ford car. That was not uncommon to do in the sixties, but the speed equipment on the engine would have not existed in 1957 as it was the early to mid sixties before after market speed parts were produced for the small block Chevy engine, something that the car in the shot is equipped with.

Continuity: When Indy and Mutt meet in the diner, the spoon on the table changes its position between shots.

Continuity: When Spalko is talking to Indy at the start, there are four Russian soldiers behind her who have their guns pointed at Indy. When Spalko says, "order of Lenin," and walks a few steps away from Indy, the soldiers raise their guns to let her pass. It then cuts to a shot of Spalko over Indy's shoulder and their guns are pointed at him again. It then cuts back to a profile shot of the pair and the guards once again have their guns raised.

Continuity: When Mutt and the Russian woman are fighting in the normal view, you see the the AK-47, but when it changes to overhead, it disappears.

Other: In the beginning of the film when they're standing around the heavily magnetized alien all the other metal object like guns and similar are being pulled towards the magnetic force field. But Indy, who is right up and close to the thing, has a metal strap for his bag that is unaffected and stays still, when it also would've pulled towards the alien.

Visible crew/equipment: In the beginning of the film when Indy uses his whip to disarm one of the Russians, when he "uses" his whip to pull the gun away, a wire can be seen on the end of the barrel to pull it up.

Continuity: In the beginning of the film, when the Russians are talking to Indy, his shirt is tucked, then in another shot it's untucked, then it's tucked again. This continues for about 3-5 shots.

Revealing: Right after Indy comes out of the refrigerator, after the nuke exploding, the scene changes to an airfield with two cars driving across the screen. These two cars are obviously CGI, as the first car turns, despite the wheels staying pointing straight.

Factual error: On the scene where they are at the cemetery in Nazca, they show the Nazca lines right off the cemetery. These lines are so big that you need to be in a plane to actually see them. They are about 8 kms long each, and from the top of the hill in the movie they show at least three of them.

Revealing: When Mutt is riding his motorcycle the first time he meets Indy at the train station, his hand is pulling in the clutch as he rides. But with the sound and speed of the bike, the clutch would have to be out.

Continuity: The Russians arrive at the Nevada base and salute the guards. The one on the far right is very close to the barrier, next to where the corner of the house is; half a second later he is several meters behind and walking towards the barrier again.

Continuity: The drawing that Ox makes in front of Indy differs between shots: Watch the shape of the sun.

Continuity: Before Indy finds the crystal skull the mummy's head has a piece of cloth on its forehead. In a wide shot immediately afterwards this cloth disappears.

Factual error: During the fight in the rocket engine testing facility the countdown timer is of a type with electronic digital numbers. In 1957 the countdown timer would have been of a type of flipping numbers, which are mechanically changed as the timer counts down, or a nixie tube display. See films like Fail Safe and Goldfinger for such clocks or timers. LED's weren't even invented until 1962.

Factual error: In the movie they are referring to the natives as Mayan. Incas are native to Peru, Mayans to Central America and Aztecs to Mexico.

Continuity: Right at the start when the Russians pull Mac out of the car, they throw Indy's hat on the ground and there is a close-up shot of it where you can see Mac's feet right next to it. It then cuts to a relatively wide bird's-eye shot over the car as it is surrounded by Russian soldiers and there is nobody near the hat - Mac isn't even in the shot.
