Question: What was the point of the tank in the desert chase sequence having a turret? It's a British 'Mark' series from WWI. Was it a mistake?
Question: Why does Indiana Jones wear glasses? We always see him wearing round-rimmed glasses in academic settings, which implies that he wears reading glasses. In the midst of high adventure, however, he never wears glasses; nonetheless, he's able to read cryptic inscriptions and even his father's diary in the worst possible lighting conditions. Are his reading glasses some sort of passive disguise, like Clark Kent's?
Question: It's been stated that Elsa and Donovan knew how to get through the path to the Grail because Henry was talking about the way as he lay dying. But I'm still confused about when they get across the cliff. Indy threw some sand and stones across the path he 'believed' was there, but would they still be sitting there, basically in mid air for the bad guys to get across? Did they truly believe in the Grail as much as Indy and Henry did and so could walk across the non-existant path?jenn_s_h85
Question: Is there anything to suggest that someone couldn't leave the grail in the cave and come back every 50 years or so to "top off" their immortality?
Question: Is the correct grail made of wood or metal? Was the comment "the cup of a carpenter" referring to the grail looking simple or the substance it was made of? It looks like gilded wood but makes a sound when picked up like it was metal.
