3. His Students Are Engaged And Attentive
In the few scenes where Indy teaches his class about golden coffins and ancient myth, we notice that every student in the room hangs on his every word, leaning forward like drunk men at a pole dancing club. Some of the girls even swoon...
This is unrealistic. Actual archaeology lectures are filled with disengaged wasters flicking paper around, hungover people, empty seats, students doing seminar work for a different module, confused first years sitting in the wrong class, people reading magazines, and the one keen archaeologist at the front that everyone banks on to answer all the questions. And Indy himself in these scenes is inaccurate as a lecturer: he is well-dressed and enthusiastic, when instead he should be wearing a polo shirt and have that "I have other things I should be doing" look.
