Corrected entry: Indy's pilot (Jacques) has a distinct Australian accent when he states "That's just mah pet snoek Reggie". In his next sentence, he's become completely 'Americanized'. The accent has vanished.
Corrected entry: During the basket chase scene, Indiana seems to yell out "Karen," instead of "Marion." (00:40:05)
Correction: Listen closer, Indy is yelling "Marion".
Corrected entry: When Indiana and the other guy are removing the stone cover where the Ark is kept, they are struggling, yet they can lift the Ark out with relative ease. The Ark is made of solid gold and the lid itself is said to need two men to lift, plus it should contain the two stone tablets with the ten commandments on. It should have weighed just as much if not more than the stone covering.
Correction: I think the lid was made of solid gold.
Correction: The Ark was not made of solid gold, but of acacia wood covered with gold leaf (See Exodus 37:1-2).
Corrected entry: In the Well of Souls, Marion's underwear changes from white to black.
Corrected entry: When the seaplane leaves San Francisco it flies west over the complete Golden Gate bridge. The movie is set in 1936, the Golden Gate bridge wasn't completed until 1937.
Correction: The bridge's structure would have most likely been completed by then, with only the roadway still under construction.
Corrected entry: U-boats were more than four times as fast on the surface (running on diesel engines) than when submerged (running on batteries). Since Germany was not at war at this time they would have run the boat on the surface almost exclusively. Since the boats were so hard for other surface vessels to see, the Captain would have maintained a constant look out on deck. There is no way Indy could have stayed hidden for the entire voyage.
Correction: While it is true that the German U-boat was 3x-4x faster on the surface, it is equally true that in the treaty or Versailles, Germany was banned from possessing U-boats. (The U.K. was still upset about costs exacted in WWI). A German U-boat approaching any ally or neutral ship would have to submerge, even before the war had started.
The original mistake is valid and the correction's reasoning is wrong. While the Nazis did build U-boats in violation of the Versailles Treaty right away after they took power and tried to hide it initially, this practice was an open secret pretty soon and eventually legitimized by the Anglo-German Naval Agreement of 1935, well before the movie takes place. They would not have to hide a U-boat from anyone at that time.
Correction: The pilot could have just been immitating an Australian accent at first.
