Visible crew/equipment: Right away as the alarm goes off at the bomb test site, you can see a man walking reflected in the window behind Indy. There is not supposed to be anybody else there.

Visible crew/equipment: As they are running away from the ants, you can see a rig of stage lights under the jeep Col. Spalko's crew was driving.

Continuity: When Col. Spalko begins cutting the leather covering the alien corpse in the casket, no straps are seen. In the close-up shot a strap is suddenly visible.

Continuity: At the beginning of the movie where Indy is talking to Spalko, his hands keep alternating between being in his pockets and 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 taking place in 1957, yet the motorcycle that Mutt rides 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 of 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 climbing down the cliff you are able to see for a brief second the cable from the harness 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 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 change.

Continuity: In the scene where Indiana Jones is locked in the chair in the Russian camp there is a reel to reel tape machine running to Indy's left. When you first see it the tape on the left 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: 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: 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: When Indy's in the tent facing the skull with his wrists tied, from one angle his hands are clenched fists, but from a different angle they hang loose. Since angles keep swapping, the difference is noticeable because the position is not continuous.

Factual error: In the scene 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.

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

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

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.

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