!!The first movie provides examples of:
* EnsembleDarkhorse: Jed and Octavius originally had minor roles in the first film, but after test screenings they proved so popular reshoots gave them a [[IncrediblyLamePun larger presence]].
** The Easter Island Head is also quite popular.
* HoYay: A lot of characters, but most noticeable with Jedediah and Octavius - lampshaded with a ShoutOut to ''BrokebackMountain''.
-->'''Jedediah''': "I ain't quittin' you!"
* WTHCastingAgency: '''[[CrazyAwesome Theodore Roosevelt]]''' is played by ''Creator/RobinWilliams''?
** Hey, it ''worked''.

!!The first sequel ''Battle of The Smithsonian'' provides examples of:
* AdaptationalAttractiveness: AmeliaEarhart was pretty cool, but she didn't look anything like Creator/AmyAdams.
* CriticProof: While not hated, the films elicited a ho-hum from critics while audiences loved them.
* CriticalResearchFailure: The combination to the tablet is the value of pi. Ancient Egyptians had no concept of pi.
** Nor decimal notation, for that matter. [[http://en.wikipedia.org/wiki/Indian_numeral_system That was invented in India a millennia later.]]
* CrazyAwesome: Larry fights off Kahmunrah with a ''flashlight''. Awesomest sword/flashlight duel ever.
* MemeticMutation: "Boom! Boom! [[CrowningMomentOfFunny Fiya powa!]]"
** Custer mispronouncing Sacajawea's name over and over.
** "That's the way, uh-huh, uh-huh, we like it!"
** "ITT, bro? Intent To Touch?"
** I am ______, and I have come BACK! TO LIFE!
* NeverLiveItDown: [[spoiler:Custer again.]]
* RetroactiveRecognition: Joey Motorola, the helpful sailor who Amelia and Larry run into in the picture of V-J Day in Times Square; after star turns in ''Film/{{Fanboys}}, Film/TropicThunder, and Film/ShesOutOfMyLeague'', you probably know who Jay Baruchel is by now.
* StrangledByTheRedString: Larry and Amelia. Amelia screwed around with most of the other exhibits while Jedidiah's life was at stake while Larry looked like an idiot in comparison and everyone around the complex just said that they were a cute couple.
** Which is even weirder when you consider that Amelia is a ''mannequin''
* UnfortunateImplications: As [[WebVideo/BadMovieBeatdown Film Brain]] points out in his review, Amelia is a mannequin and everyone continually tries to pair her with the human Larry. As he puts it, it's like a nicer version of shipping someone with a blow-up doll.
** At least Larry himself realizes how very wrong that is, and he tries to tell her why, though he's interrupted halfway through.

!!The second sequel ''Secret of the Tomb'' provides examples of:
* TearJerker: The fact that this film will end up being among the final films of both Mickey Rooney and Creator/RobinWilliams.
