* ActorAllusion:
** Donovan (whose actor played a Bond villain in ''Film/ForYourEyesOnly'') shoots [[BadassGrandpa Dr. Jones, Sr.]] with a Walther PPK. Not only does SeanConnery get shot, he gets shot by ''[[Film/JamesBond his own gun]]''.
** Also, the opening sequence has Indy getting Harrison Ford's scar (which originated in an auto accident) when using a whip for the first time as a teen.
** Donovan dies in the same manner as his character Scaroth killed Professor Kerensky in an episode of ''DoctorWho''.
* ActorSharedBackground: In the opening sequence, Indy is a Life Scout. Harrison Ford was a Boy Scout in his youth, and attained the level of Life Scout.
** On a side-note, Life Scout is the second highest rank in the Boy Scouts, just below Eagle Scout. A bit of minor black humor in Scouting is that it's called "Life Scout" because not making Eagle is what you'll regret for the rest of your life.
** Indy tells his class "If it's truth you're interested in, Dr. Tyree's office is right down the hall." When he was in college, Harrison Ford took a philosophy course taught by Dr. William Tyree.
* DawsonCasting: An inverted example. Allison Doody was 22 years old when ''Last Crusade'' was filmed, but she plays Elsa Schneider, who can be assumed to be at least around 30 years old considering that she's got a doctorate and she's a highly-respected art professor.
* FakeNationality: Welsh John Rhys-Davies plays Egyptian Sallah, Irish Alison Doody plays Austrian Elsa Schneider, and English Julian Glover plays American Walter Donovan with an impeccable accent.
* LifeImitatesArt: [[http://www.washingtonpost.com/world/europe/remains-of-king-richard-iii-identified/2013/02/04/d79e87b2-6ebb-11e2-ac36-3d8d9dcaa2e2_story.html?hpid=z3 This 2013 discovery is very interesting on its own]] and more unusual considering in this film, Indy, Elsa and Marcus were looking for the "Tomb of Sir Richard".
* PlayingAgainstType: Creator/SeanConnery, the original Film/JamesBond who spent most of his career playing tough, cunning heroes, here plays a squeamish "bookworm" who is not prepared for his son's rougher, tougher adventures - and he's absolutely ''hilarious'' in the part.
** And he ''still'' sleeps with Ilsa.
* RealLifeRelative: Mrs. Donovan is played by Isla Blair, Julian Glover's wife in real life.
* RealitySubtext: Sallah is quite surprised at Indy's true name and the origin of his nickname, "Dog? You are named after the dog!?". GeorgeLucas indeed named Indy after his pet dog, who was also the inspiration behind [[StarWars Chewbacca]].
* ThrowItIn: "She talks in her sleep", was an ad-lib by Connery.
* WeNamedTheMonkeyJack: Indiana was actually the name of George Lucas' malamute, who also served as inspiration for [[{{Franchise/StarWars}} Chewbacca]].
* WhatCouldHaveBeen:
** Had Creator/SeanConnery turned down the role of Henry Sr., Creator/GregoryPeck and Creator/JonPertwee were backup choices.
** In an early draft, the character of "Fedora" was going to be Abner Ravenwood, father of Marion Ravenwood, who was mentioned in ''Film/RaidersOfTheLostArk''.
