Revealing mistake: When young Indy jumps from his car to the motorbike and fights against a German - and the following scene where he rides on the bike towards the train - his body and especially his face are a blatant CGI creation with unnatural movements, dead eyes, and waxy, lifeless expressions (most noticeable in theater screenings). (00:05:53)
Continuity mistake: During the parade, a red convertible skids and stops in front of Indy. Shot changes and it's skidding and stopping again.
Factual error: In the prelude scene, when Indy enters the car where a number of German soldiers are having supper, the latter are singing "Lili Marleen", a popular soldier's song in the 1940s. The only problem here is that the song was banned in Nazi Germany from 1942 after its last performer, Lale Andersen, was found to have sympathized with Jews. With common soldiers singing it while a strict officer might burst in among them at any time, it would have meant extremely harsh penalties for them.
Answer: I remember that Archimedes gave Indy the dial, but he kept the wristwatch.
