Audio problem: When Russ jumps from out behind the bush and says, "I say that ant is ours", his mouth doesn't move.
Audio problem: During the bee scene, Ron tells Amy "It's all your stupid fault", but from a side angle he's not mouthing the lines.

Continuity mistake: When Amy is in the kitchen cleaning, she starts mopping the floor, then dancing with the mop held upside down. The mop starts out wet, but when she's dancing it's dry (either that or she would be getting dirty mop water in her face while the mop is being flung around).
Amy Szalinski: If you were my brother, I'd put myself up for adoption.
Ronald 'Ron' Thompson: Yeah, I hope your face ends up on a milk carton.

Trivia: In the open-matte print, right after the credits, the support beams of the movie lot walls are visible, painted in blue to simulate the sky. In the theatrical version and the current Disney+ streaming movie's original aspect ratio (bottom picture), one can still see the beams for a split second after the postman puts the letter in the mailbox (though there's no way here to identify them as lot walls).
Question: When Don asks why Russell Sr. won't go on their trip, he says that Mae can't go due to "plumbing." Was he referring to her being on her period?
Answer: More along the lines of a serious health problem related to her "plumbing".
