Night at the Museum/YMMV

The first movie provides examples of:
"Jedediah: "I ain't quittin' you!""
 * Ensemble Darkhorse: Jed and Octavius originally had minor roles in the first film, but after test screenings they proved so popular reshoots gave them a larger presence.
 * Ho Yay: A lot of characters, but most noticeable with Jedediah and Octavius - lampshaded with a Shout Out to Brokeback Mountain.


 * WTH Casting Agency: Theodore Roosevelt is played by Robin Williams???
 * Hey, it worked.

The sequel Battle of The Smithsonian provides examples of:

 * Adaptational Attractiveness: Amelia Earhart was pretty cool, but she didn't look anything like Amy Adams.
 * Critic Proof: While not hated, the films elicited a ho-hum from critics while audiences loved them.
 * Critical Research Failure: The combination to the tablet is the value of pi. Ancient Egyptians had no concept of pi.
 * Crazy Awesome: Larry fights off Kahmunrah with a flashlight. Awesomest sword/flashlight duel ever.
 * Memetic Mutation: "Boom! Boom! 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?"
 * Never Live It Down:
 * Retroactive Recognition: 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 Fanboys, Tropic Thunder, and She's Out of My League, you probably know who Jay Baruchel is by now.
 * Strangled By the Red String: 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
 * Unfortunate Implications: As 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.
