FILM 1299: THE LEGO MOVIE
TRIVIA: The term "Master Builder" is actually an official designation by the Lego Company; per their website, "LEGO® Master Builders are the highly-trained and super-creative builders who design all of the official LEGO sets. Other LEGO Master Builders create giant, detailed sculptures out of LEGO bricks for LEGOLAND® Parks and special events all around the world."
The word "Lego" is never spoken in the movie.
Lord Business is president of Octan, a fictional gas station brand that first appeared in 1992 and has since been featured in numerous Lego sets.
In order to add more realism to the movie, the Lego bricks have scratches, fading, and even fingerprints to make the movie look like someone was manipulating real bricks in a stop-motion fashion. The Bricks are also affected by their locations, with the bricks in The Old West realm being more dusty and faded from the sunlight.
Benny, AKA the "1980-something space guy", a Minifigure from LEGO's classic Space line, has a broken helmet and a worn-out, scuffed logo on his suit, similar to how many real-life Space Minifigures look after being used. The helmet is even shown to be cracked at the same spot where the real-life LEGO piece would usually break.
With the exception of unique pieces for the characters in the film (i.e: President Business's hair and evil helmet) every Lego piece in the movie actually exists and can be used in sets.
The creators deliberately tried to make the movie feel like stop-motion, and avoided making the computer-generated effects look too obvious. This was done to make the movie look like it contained real Lego.
After the first "Everything is Awesome" sequence, the title card that says "5 Hours Later" in Lego is a photograph of real Lego, and one of the few non-CGI Lego shots in the movie. The ending credits are also real Lego animated by stop-motion.
Morgan Freeman stated that the Batman in this film is his favorite incarnation of the character of all time.
The numbers seen with the pieces when Master Builders were assembling their free form models are the official Lego Element ID's (or part numbers) for each of the components used in each of the models.
In Emmett's apartment, there is a poster for a movie called "Macho and the Nerd" which is the Russian title for a previous Phil Lord and Christopher Miller movie, 21 Jump Street (2012).
When in the Octan tower, Wyldstyle goes off and tells them to wait for her signal. When she gives it, it's the "Super Secret" signal from Team America: World Police.
