Factual error: At the beginning of the movie where the convoy stops at the gate to the military base, the fence has "Razor Wire" on the top, not the period-correct barbed wire. Razor wire came into use in the late sixties by some industries, but the military did not use it until the eighties.

Continuity: At the beginning when Indy is talking to Spalko, his hands keep alternating from being in his pockets to just resting at his sides between shots.

Visible crew/equipment: When the characters are wading out of the river onto the shore (after the waterfall scene), a metal swimming pool ladder can be seen in the lower right corner of the screen.

Factual error: In the warehouse scene, the lights and other metal objects are affected by the box's magnetic field. Yet the soldiers easily lift the box into a metal truck to load it and slide it forward. If the box's magnetic field was as strong as suggested, it would have dragged the soldiers forward as it was magnetically attracted to the truck, and it would have taken much more effort for them to slide it onto the truck bed once it was stuck there.

Continuity: In the beginning, when the trucks are being stopped at the Army gate in Nevada, one of the guards raises the bar immediately, but in a new shot, it is down and stopping the cars from continuing.

Factual error: The movie supposedly is set in 1957, yet Mutt's motorcycle is based on a 2000 or newer Harley Davidson softail, showing the modern-day controls and Twin Cam motor, instead of the panhead motor that would have been the period-correct engine for 1957. It also has a front disc brake - you can see the master cylinder on the handlebars. Again, out-of-place on a 1957 bike.

Continuity: After Indiana and team fall off the disappearing stairs as they make their way into the lost city, they are walking around in the water. But when they step through the next door into the treasure room, all are completely dry.

Visible crew/equipment: When the female Russian is descending the cliff, you can briefly see the harness cable that is holding her up right next to the rope on which she is climbing down.

Continuity: When Indiana and Mutt are in the diner, at the start of the scene there is a pretty blonde girl sitting at the counter just past the corner. A moment later, her seat and the one next to it are occupied by the two Russian guys in suits, and she is talking to a guy with glasses who was earlier by himself. Not enough time had passed for that to change.

Factual error: Indy and Mutt fly to Nazca, Peru. Nazca is only 4 hours away on bus from the capital Lima, yet the city they show on the movie is Cuzco, which is 24 hours away from Lima. Cuzco is on the east side of the country, Nazca is on the west coast right next to Lima. Also, back in 1957 only Lima had an airport, yet they show a Nazca airport that didn't exist.

Continuity: When Indiana Jones is locked in the chair at the Russian camp, there is a reel-to-reel tape recorder machine running to Indy's left. When you first see it, the amount of tape on the left reel is low. Then, when Irina Spalko walks in, she goes over to it and flicks a switch. As the camera moves out, the tape on the left-hand reel is suddenly nearly equal to the one on the right.

Factual error: When Indy and Mutt are flying to Peru, a Pan American Aircraft is shown. It is an Antonov AN-2. Pan Am never flew this Russian aircraft! Also, the shot is backwards; the writing on the aircraft (airline name and registration) read backwards.

Continuity: In the tent, Indy's wrists are tied and he's facing the crystal skull. From one angle his hands are clenched fists, but from a different one they hang loose. The difference is noticable because the angles keep swapping and the hand positions are not continuous.

Continuity: In the forest car chase, towards the end of Mutt's sword-fight, we see Indy driving a car behind Mutt. It cuts to Mutt picking up the skull and then back and Indy's car has disappeared. Then, as Mutt falls off the car, magically Indy appears in time to catch him.

Continuity: In the jungle chase scene, Indy and the others blow up the front-running plough machine. They then continue to drive around in a ploughed jungle alley. They should be hitting a lot of trees.

Factual error: In the church, you can see modern brass panic bars on the doors.

Continuity: During the beginning chase with Mutt and Indy, the bus goes from next to them in one shot to behind them in another.

Factual error: The movie shows Mayan warriors talking Quechua in the Peruvian jungle instead of showing Inca Warriors.

Continuity: When Indy and Mutt first meet in the diner scene, look out the window behind Indy. A group of leather-clad bikers are sitting and talking on their motorcycles in one shot, then it cuts away, then back again, and they have vanished. Now there are just people walking past the window. This happens at least three times during the scene.

Factual error: When Indy is getting decontaminated after the atomic explosion, the workers are using the M17 protective masks. These masks were not in use until the late 1960's.
