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).

Continuity mistake: A woman is shot at at the college and lies down with her right leg bent. A man tries to move her but is killed before he does. The shot changes and her right leg has swapped to lying straight.
