If you're asking where the similarities begin, we'll start with appearances. President Business always wore a bright red tie, which is Trump's most oft worn color. In addition, the hairstyles are similar. President Business had a custom Lego hairpiece that was designed just for the movie. It also looks like a dyed combover with streaks of gray at the bottom. Indeed, President Business bears a striking physical resemblance to Trump.
Aside from appearances, the next parallel is the residence. In The Lego Movie, President Business lived at the top of a black tower, where he conducted all of his affairs. Before assuming the presidency, Trump lived the same way. He lived and worked from his apartment and office in Trump Tower, which is a dark looking monolith in New York City.
The next similarity is the building of walls. In the film, the various Lego themes (e.g., Bricksburg, The Old West, Middle Zealand, etc.) are separated by walls that the characters are able to navigate. President Business constructed these walls to keep the themes from overlapping and making sure everything stayed in place. Trump is looking to do something similar by separating the U.S. from Mexico by a wall, which will keep things "the way they are supposed to be, permanently."
The final similarity, which makes all of this too much to be coincidental, is the opening scene of The Lego Movie Part 2 when the Duplo aliens begin attacking. As the buildings fall and the emergency becomes real, President Business emerges dressed to go golfing and is last seen speeding away in a golf cart. This is exactly what Trump did on February 15, 2019. He declared a state of emergency and then flew off to Mar-a-Lago for a weekend of golf. The producers of The Lego Movie Part 2 knew all of this in advance and slipped that in there as a "we told you so."
The hidden messages in both Lego Movies are clear. The Illuminati knew that Trump was going to be elected, and they likely orchestrated the whole thing to further isolate his followers from the mainstream brainwashed population. As the order always does, they foreshadowed their plans in films released before the events transpired. We were warned and didn't listen. Like so many others, we were enamored with the idea of Trump turning on the established order and disrupting the status quo, but we were betrayed. And to make matters worse, The Lego Movie Part 2 foreshadows some very dark and destructive times ahead for America.
In the sequel's opening scenes, Bricksburg has become a desert wasteland, its buildings reduced to rubble. The only remaining trace of civilization is an anarchical community called Apocalypseburg, which is built around the ruins of the Statue of Liberty. This is what's most terrifying. Is The Lego Movie Part 2 warning us that our nation is about to undergo some sort of large scale devastation? Further analysis of this film and others is needed to determine completely. Seeing Lady Liberty in ruins is nothing new in the movies. We've seen it in Independence Day and Deep Impact, but the notion that The Lego Movie foreshadowed a wannabe dictator president is what we find disconcerting. The messaging has caused us to reconsider everything we previously thought about Trump.
Indeed, the Illuminati is clever, and if we're correct in our analysis on President Business, then we erred in allowing for ourselves to be duped by the order. The All Seeing Eye will not fool us again.
