Mutt drives his motorcycle into the library then slides on the floor, pushing a student on a chair with the wheel, he then asked Indy a question about history. Why doesn't he panic? When your teacher is out mystery solving, artifact hunting, people saving, you know he's going to be out for days on end. Ask a question when you can, because you don't know when he's going to be back.
Also, he's a living embodiment of what Indy scolded the whole crowd for: an archeology student who spent so much time in the library, he didn't even register the weirdness of a bizarre real-world event because he had his head buried in books.
To many, Indiana Jones surviving a nuclear blast is a Wall Banger already being known as "Nuking the Fridge". To me, if he had merely gotten in and survived, I would have thought the same. The fact that the fridge was flung through the air, while everything else was disintegrated, and that he came out with barely even a bruise, just tells me that this is Refuge in Audacity. — Lord TNK
After watching the last crusade for the first time, I immediately noticed that Indy drank from the holy grail, an act that can heal fatal wounds as shown with his father. Even if such an act does not grant immortality to Indy once he left the temple/cavern/thing, I would have been disapointed if Indy did not have an upgrade, and KOTCS actually shows us an Indy over 50 years old who is not only still in good shape, but can also shrug wounds, even if said wounds are radiations: it is not an Ass Pull, it is a Chekhov's Skill from the previous episode. — Nixou
Poster artist Drew Struzan said George Lucas wanted the teaser poster for KOTCS to be the shot of Indy's silhouette looking at a mushroom cloud because he loved that image. Paramount Studios wouldn't go for it but Lucas asked Struzan to make a painting for him so he could keep it. Ultimately it wasn't the idea of Indy surviving an atomic blast hiding in a refrigerator that Lucas liked, it was seeing a hero of the early half of the 20th century witnessing and juxtaposed against the nuclear nightmare of the latter half.
The opening of KOTCS opens with a Match Cut as the Paramount logo transitions to a mole hill. This is a reference to the saying "Make a mountain out of a mole hill", which means making a huge issue over a minor point". And that's just what happened! Fans got worked up over this tiny detail, in a manner not unlike the scorn the Star Wars prequels have had.
Actually, every Indiana Jones movie has started that way, with the Paramount logo turning into something else. — General Nerd
But using a mole hill for the match cut must have been some sort of a reference to that saying. Almost like Lucas and Spielberg were egging on the haters. — Premonition_45
On the other hand, isn't Indy immortal because he drank from the Holy Grail?
No. Both Sir Richard (the knight that left his pal to guard the Holy Grail, and was entombed in Venice) and Henry Jones Sr also drank from it, but they still died. My guess is that drinking from the Holy Grail just heals you quite fast and keeps you healthy for some time, as well as extending your life.
Half true. All three crossed the seal, so they lost their immortality.
It took me a bit to reconcile the fact that Indy was going after aliens rather than religious artifacts. But then I remembered that The Indiana Jones series was meant to be a throwback to the adventure serials of the 1930's. Pulp stories from that era was often based on magical artifacts and ancient legend. The 1950's saw a new fascination in outer space. So this story, set in the 50's, is reflective of 50's pop culture - with a focus on the Space Age and visitors from other worlds.
Another scene in KOTCS often criticized for being ridiculous/out of place/etc. is the one where Mutt ends up in the treetops with those monkeys. But, this troper was watching Raiders of the Lost Ark the other day, and what did he see? - a scene with Indy and Marion wandering through a marketplace, holding a monkey, and jokingly talking about it as if it was their son!
Marion's son goes by the nickname "Mutt"...which seems like a generally scruffy Rebel Without a Cause name until you think about who his father turns out to be. Henry Jones Jr. named himself Indiana after the family dog.
...My mind. You have just blown it.
In the library scene, Indy tells the student the he should get out of the library to become a good archaeologist. This contradicts a line from The Last Crusade when he tells his students that 70% of all archaeology is done in the library. But that's just it! It's the last 30% that counts!
Although, in Last Crusade, Indy had acknowledged the contradictory nature of his teaching vs. practice, as the passage to the tomb of Sir Richard was marked by a giant "X", despite his insistence that "X never, ever, marks the spot.".
An "X", moreover, which he discovered in the floor of a library.
In KOTCS, the gold coins in Orellana's tomb is shown to be magnetic, something that gold is absolutely not. However, it's entirely possible that those coins weren't actually pure gold, since mixing copper into "gold" coins was common in 16th century. Copper is magnetic, so it's likely those impurities that allowed the skull to attract them.
Mutt does mention that gold is not magnetic, which is something that clues Indy and Mutt to the fact that the crystal skull is far more strange than what they thought.
Hmm, he actually didn't mind being called Henry. It's his real name, after all. What he didn't like was being called "Junior". Only his father did that, and it has the Unfortunate Implications of Henry Sr. seeing his son as nothing but an appendage of himself and a disappointment as a result, because Indy didn't pursue the same career in life Dad did.
The fact is, after 50+ years of having adventures around the world searching for relics of different cultures, getting involved in espionage in two world wars and witnessing first-hand the power of three major religions, the only thing that could possibly surprise Indiana Jones by this point in his life would have to be aliens (and having a son he never knew about).
At the end of the film, Indiana notices that they aliens have collected artifacts from around the world. The temple they are in is implied to be three or four thousand years old, or "as old as the pyramids". Indiana feels a connection to the aliens because he says they are archaeologists (evidenced by their collection of ancient artifacts from India, China, Europe, etc.) but if the collection is really thousands of years old, those artifacts wouldn't have been ancient when the aliens collected them. The aliens would have been more like contemporary art collectors.
During the skirmish at the Area 51 warehouse, several of the storage crates are damaged, including the one that holds the Lost Ark. Keeping the events of the first film in mind, what if the Ark's lid came off?
The Ark only goes after those (good or bad) that look into it. Since no one had the time to it as they were so busy chasing the new MacGuffin, the worse that could happen would be the warehouse burning down in Holy Fire.
