Corrected entry: In the bar fight scene, a voice yells out "get that greaser!" just before the fight breaks out. However, the term 'greaser' (used to describe a leather jacket wearing youth of the 1950's) was not used to describe this clothing style until later decades - at the time they were called "hoods".

Visible crew/equipment: Indy is at the nuclear test site and exits the house and comes out front. He knocks over the boy on the bike and air raid siren goes off. Just as he stands upright, in the window with curtains, you can see a reflection of a crew member walking by.
Visible crew/equipment: After everyone has fallen into the water beneath the obelisk and the skull has been retrieved, Indiana is leading everyone out of the water and a prop light can be seen on the big rock spike behind Mutt. (01:40:25)
Corrected entry: When Indy opens a shotgun shell to extract its shot, these pellets are then magnetically attracted to the case which contains material from the 1947 Roswell UFO incident. Although it was correctly pointed out that the shell's hull was made of paper with a felt wad, until the 1980s, the pellets were formed from lead and thus would not be influenced by magnetism. Due to lead's toxicity, the shot types that are mandated for waterfowl hunting include steel, bismuth, and several combinations of tungsten, iron, nickel, tin, etc. Another issue with that scene is: how did the pliers produce such a precise cut around the hull? The implement itself wasn't a "multitool" with a knife blade incorporated into the handle. All he had to do was squeeze the crimped end of the shell a couple of times to open it.
Correction: That shotgun shell had buckshot it in it which would be steel and therefore magnetic. The bigger issue is that he tore off the primer end, which realistically can only be torn off with pliers, and the only thing that should have spilled out would be gunpowder. If he wanted to get the buckshot pellets out he would have torn open the crimped "business end" of the shell. As depicted in this film, that shell would not have functioned as its components were in the shell in reverse.
Corrected entry: Indy tells Mutt at the diner that Mutt "brought a knife to a gun fight." This is almost a verbatim quote from Sean Connery's character in "The Untouchables."
Correction: True, but the only connection between these movies is one actor. Who is only seen in a picture in Crystal Skull. This is not trivia regarding anything Indiana Jones related.
Correction: "Bring a knife to a gun fight" is an idiom that's been in use, probably, since guns have existed. There's no reason to believe this is a reference to The Untouchables.
Correction: The movie is set in 1957. The term "greaser" was in use at that time. Greasers did not necessarily wear leather jackets, but did usually have their hair greased back and were generally from low-income families.
