Continuity mistake: When Emmet goes to buy overpriced coffee, Larry the Barista says "That's 37 bucks." In the background, you can see a woman in a Fabuland T-shirt is right next to the window. When Emmet replies "Awesome!" she has moved a (Lego) metre forward and someone is opposite her. (00:05:05)
Continuity mistake: After crashing the pig drawn car the characters fall onto a train car, the rail car directly behind the one they fall on is open and carrying barrels. In the very next scene none of the characters have moved, but there is now an enclosed train car there. (00:35:25)Kimberly Hannen
Trivia: When Wildstyle throws off a biker during the motorcycle chase, the biker lets out a Wilhelm scream.

Dumbledore: It's pronounced Dumbledore.

Vitruvius: I thought you said Dubbledore.
Vitruvius: Ah, we gotta write all that down 'cause I'm not gonna remember any of it, but here we go. The Special will now give an eloquent speech.
Question: In the real world, during the "Let's put It All Back" sequence, the son's creations are set up fighting Micro Managers. When the dad is rearranging everything, he never seems to do anything with them. If they weren't part of the Lego displays he built, why didn't he change them?
Question: In the end of the movie, what does Vitruvius mean when he says "I liked Emmet before it was cool"?
