Deliberate mistake: It is totally unlikely that a museum as careful and important as the Smithsonian would leave the crates un-nailed, which could make the pieces inside get damaged. Of course if the crates weren't open, none of the figures could come up to life.
Night at the Museum: Battle of the Smithsonian (2009)
1 deliberate mistake - chronological order
Directed by: Shawn Levy
Starring: Robin Williams, Owen Wilson, Ben Stiller, Amy Adams, Steve Coogan, Hank Azaria
Visible crew/equipment: In the scene with Darth Vader and Oscar the Grouch, watch Darth Vader's eyes. You can see the light screens and crew reflected in his eyes in every shot.
Larry Daley: This is the Smithsonian! This is the big leagues!
Trivia: Five different actors from the U.S. and U.K. versions of The Office appear in the film: Amy Adams, Ed Helms, Mindy Kaling, Craig Robinson, and Ricky Gervais.
Question: At the end of the movie Amelia and Larry are saying their goodbyes - Larry tries to bring up what will happen to Amelia at sunrise, and Amelia says that she knows what will become of her. Is it implied that Amelia will not make it back to the Smithsonian before sunrise and turn to dust, or is it implied that she will make it back, but will not be able to come to life at night due to not having the tablet near her?
Chosen answer: Amelia has no idea about the turning to dust at sunset consequence, but what she does know is she will disappear and not be found, as what happened to the real Amelia Earhart.
