Night at the Museum: Battle of the Smithsonian

Other mistake: When Larry first enters the main storage room, he has to go by the guard Booth. A voice says "ID" then acknowledges that it's "Brundon, later dude". When it shows Larry from behind it shows a clear shot of the inside of the entire security room. It is completely empty. Did a ghost ask for the ID?

Other mistake: In the fight scene between Larry and Kahmunrah, Larry throws the tablet to Amelia Earhart and she opens the gate, but she didn't say the magic words to open it or even worse she doesn't know those words as Kahmunrah.

Suggested correction: The gate start to open right after pressing the buttons on the tablet, no magic words were needed. Kahmunrah was talking something with his eyes closed, but it had nothing to do with the gate opening.

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.
