Goofs

When they go into the hotel for the auction it is night, when they come out after the fight it is day time.

During one chase, Indy's tuk-tuk makes a sharp turn at a T intersection between two very narrow walled-in roads. In the next cut, the pursuing full sized sedan has somehow made an impossible turn and is right behind them again.

When Indy and Helena go through a narrow tunnel to the bridge, they end up covered in bugs and insects. Only a few minutes later when the Nazis go through the same tunnel, there don't seem to be any bugs.

Just before Teddy and the big guy he is cuffed to fall to water, the bridge over the torrent breaks. But when the Nazis leave Archimedes' tomb, they pass over the bridge that hangs again.

While on the plane to Tangiers, Indy reminisces of the night he broke into Baz's room while Basil was about to smash the Antikythera mechanism. Indy grabs the hammer from Baz and pulls him away but a few seconds later Baz has the mechanism clasped against his chest.

Indy and Helena dive at a shipwreck supposed to be 2,000 years old with its wooden hull clearly visible and recognizable. In most waters, such as the ones of the Aegean Sea, wood does not last more than a couple of decades. In fact, Greek and Roman shipwrecks in the area are found by their non wooden materials, such as bronze, and their cargo, such as vases and ceramics, which is where the actual Antikythera mechanism was found.

There's no way Indy and Helena could find skeletons or any trace of human remains when they dive at a 2,000 years old wooden roman ship. All biological stuff will be obliterated by time and decomposition, especially in highly oxygenated water like Mediterranean ones.

The train transporting antiquities to Berlin is fully lit up internally, but the window blinds are not down. During an enemy air raid such would make it an easily spotted target.

While this movie's title namesake object (the dial allegedly built by Archimedes) refers to a real antique device fragments of which were recovered from a 2000-year old ship discovered in 1900, that device is always called the "Antikythera *Mechanism*". Antikythera is not the name of the device itself (as it is in the movie), but of the Greek island nearest where the mechanism was found, and archaeologists like Indiana Jones and Basil Shaw should know that. Additionally, although the island's name is usually pronounced with emphasis on the "ther", the emphasis is usually placed on the "ky" syllable in the name of the mechanism, and this is not done by the characters either.

There's no way to go from main landing gear nacelle to air-frame interior through wing, there's the main fuel tank between.

In Tangier, there's a shot showing Helena's feet pressing a pedal. However, this kind of Tuk-Tuk is moved by gripping the gas handle and the brakes are located on the handlebar, meaning there aren't supposed to be any pedal there.

"There's a clutch for your left foot which works exactly like a car."

When Indiana Jones and Helena go diving with the other two divers, they go straight down without equalizing the pressure in their ears at any point. This would result in certain eardrum rupture at the depth shown in the film - at least 20 meters.

They had to have been equalizing on the way down. And the depth of the ledge they went to was nowhere near 20 meters - closer to 10 meters, as can be seen by the bullets fired at them. Also, the descent actually happened. Actors were in the water, without ruptured eardrums. This wasn't CGI.

When Helena and others are sea diving and go to surface at high speed they would die due to air volume increased in their lungs.

They are perfectly safe as long as they don't hold their breath. Exhaling all the way allows expanding air out.

Methane is odorless so it is undetectable by smell and does not cause coughing. But, it's highly explosive and entering a room saturated with methane gas carrying a non-explosion proof lamp will blow you in a myriad of shattered pieces.

Lab grade methane may be odorless, but naturally generated methane is not. And, as MythBusters (2003) showed, a precise stoichiometric ratio of 9% is needed before exploding.

When Indy punches out the Nazi car driver and pulls him out of the car, where does he go? The reverse shot shows Nazi outriders on the side of the car where the driver would have fallen, as well as passengers getting into the rear, on the same side. He should have been on the ground for everyone to see.

There was a war still happening, an aerial bombing raid just happened, looting was happening and the two officers getting in the car were not responsible for, didn't care about and didn't bother to notice random bodies lying around. They were happy just getting the ride and didn't want to waste their time dealing with it, perhaps assuming the underling would.

The sidecar should have thrown the motorbike away or off course when hitting the tree.

On the train, the anti-aircraft gun fires continually until the ammunition belt runs out. These guns were fed by ten (10) round magazines.

During the Astronaut parade, the first trumpeter next Indy is not even touching the trumpet mouthpiece.

Teddy wonders if he'll be able to fly the plane, and uses the word "Nord" (named after the Nord-Aviation brand) to refer to the plane. In the French version, Teddy refers to the "Nordatlas". But the Nordatlas is a twin-engine military troop transport, not a small single-engine plane.

In the 1960s New York street exteriors, NYPD police cars are depicted in their modern day liveries of pale blue and white. New York police cars up until 1973 were painted in a livery of black, white & green.

The Roman soldiers all wear iron helmets and chain mail armor. During the time of Archimedes, most Roman soldiers would wear a small metal plate on their chest as body armor, since they couldn't afford a complete chain mail shirt. Iron helmets did not get into use in the Roman army until after the conquest of Gaul, over 1,5 century later. The Roman republican army did, however, use the oval shields seen in the film.

'The Cave of Dionysius' mentioned in the Grafikos tablet was not known by that name in ancient times. The cave's association with the tyrant of Syracuse 'Dionysius I' was coined by the painter Caravaggio in 1608.

Vicodin ES, seen on the table near the end of the movie, was not available in the US until 1978.

Although neoprene wet suits were around in the late 60's, they had metal zippers whereas in the film the suits have plastic teeth and modern zipper pulls.

46:53 Indy escaping on horseback, he is riding full speed but looking at his coat tails, they show no sign of the wind from the speed he is riding the horse.

In the Tangier club, the instrumentation of the live band doesn't match that of the Merengue music being heard.

When Indy is on board the diving boat, there is a guy playing a melodeon but the sound is that of a concertina.

In at least a couple scenes (such as when Jones is talking about the Aegean Sea), the characters' mouths don't match their words, when they are filmed from behind.

When Indiana is on top of the train, the simulated wind doesn't match the speed the train is traveling.

Streets in Glasgow, Scotland doubled for New York in 1969. In the closing shot of the film, double yellow lines can be seen on the road at a junction. These are UK road markings which mean no waiting/parking.

In the hallway of Dr. Shaw's brightly-lit house, the light switches are all in the up position. In a British house (as opposed to those in an American house) this means that the lights are off.

Jones rides the horse through the tunnel from 59th St. towards 51st St. The track and platform he ends up at is the downtown side, but the announcement says the next stop is 59th St. which is uptown.

The ticker tape parade for the Apollo mission astronauts is shown to be right in front of Hunter College. In reality, the parade was held on Broadway in lower Manhattan which is 6.6 miles south of Hunter College's location in the Upper East Side of Manhattan.

On the train at the beginning of the film, Indiana blocks a door handle with the spear of Longinus, preventing the Nazi soldiers from following him. The soldiers remain blocked until an officer on the other side of the door removes the spear. The soldiers could have broken the glass of the door to remove the blockage and open it.

After the fight on the roof of the train, Indiana and Basil Shaw look out over the countryside, standing on the roof of the train and chatting. They've just passed through a tunnel zone and have no way of knowing that there are no more tunnels, especially as the smoke from the locomotive prevents them from seeing what's in front of the train.

In the cave, Indiana is shot in the shoulder and bleeds profusely. Until he arrives on the beach, he's in fine fettle and not handicapped by his injury.

When he escapes from the Nazi castle, Indiana sets off in pursuit of the train. However, he was fighting inside the castle, so he has no way of knowing that the bad guys left on the train with the artifacts.

Indy identifies the half lion half eagle creature carved on Archimedes' tomb as a Phoenix. The creature is actually a griffin and bears little or no resemblance to a Phoenix.

Indiana says the Wright brothers were born during the Civil War (1861-1865), but neither were. Wilbur Wright was born in 1867, and Orville Wright was born in 1871.

In the Cave of Dionysus, Indiana seems very frightened by the insects. However, in Raiders of the Lost Ark (1981) and Indiana Jones and the Temple of Doom (1984), he shows no concern over them.

In the World War II scenes, Harrison Ford has been de-aged to appear young. However, Indy speaks in his old age voice.

There is a reference to the V1 rocket. The V1 was a pilotless aircraft: what is now called a cruise missile. Only the V2 was a rocket.
