Corrected entry: After the glue cap gets removed from Emmet's back there is still glue residue on his back. But towards the end of the film, the glue residue seems to have vanished.
Corrected entry: In the final scenes, the main Lego characters are eating food on Emmet's double decker couch. After the Lego Duplo aliens appear, both the couch and the food is gone. (01:32:35)
Correction: The food and the couch are just behind Emmet and the gang when the Duplon aliens appear (see closely).
Corrected entry: At the beginning of the movie, the "Bob's Kabobs" stand in the middle of the triangular public space is seen with a green awning. Towards the end during the climax, the awning is now yellow and red as it is in the Lego set #70812. (00:05:00 - 01:09:00)
Correction: Plenty of time passes between the two scenes. More than enough for the boy or his father to change the awning. For all we know, the boy changed it to green and his father simply changed it back.
Corrected entry: In the scene where Superman and the other master builders are captured, C3P0 can be seen in the background, though he appears in Han Solo's ship later in the movie.
Correction: No, the character you can see is in fact a crash test dummy. He can be seen again after Emmett jumps into the abyss.
Correction: The father cleaned the glue residue off Emmett's back near the end of the movie.
