Trivia: This is just fun. When The Architect is speaking to Neo about the different versions of The Matrix, he explains he had to change it "...to more accurately reflect the varying grotesqueries of your nature." At the precise moment he says "grotesqueries", both father and son George Bush show up on the screens. Coincidence? Nah. (01:13:00)
Trivia: In hacker terminology, a "backdoor" is a way of getting access to certain areas of sites, or getting access to computers, without being detected. This applies to the endless hall of doors as seen in Reloaded.
Trivia: It was the highest-grossing R-rated movie ever in North America until March 2004 when "The Passion of the Christ" passed it. In the history of R-rated films, it has the shortest reign as grossing champion when it held that title for nearly five months (after it passed "Beverly Hills Cop"). However, it is still the highest-grossing R-rated movie worldwide, taking over 100 million dollars more than The Passion of the Christ.
Trivia: The long haired white wearing goon of the french speaking guy is Reeve's martial arts trainer for the movies.
Trivia: When the first ship is blown up by the sentinel's bomb, they show the sentinels moving towards the ship, notice in the background, there are the remains of one of the old Zion's. You can make out the long central shaft connected by many bridges. This raises the question of how literal the Architect was being when he said that any trace of their existence was removed. Hopefully Revolutions will clear it up...
Trivia: At least two points in the movie the number 101 is shown ... 101 was the apartment number of Neo in the first movie. In addition, the freeway race is on the 101 and the 303 (Neo-1, Trinity-3). In addition, 101 is the binary number for 5. 5 Matrixes have already passed and the current one is number 6.
Trivia: In "The Matrix," Smith tells Morpheus several interesting things when they are trying to get the access codes for Zion. When he is talking about the humans, he says what he hates is the smell. "I feel I have somehow been infected by it. It's repulsive. I must get out of here, I must get free." Later he says "Once Zion is destroyed there is no need for me to be here." These are all foreshadowing for Reloaded and Revolutions.
Trivia: In a Dateline Special on the special effects of the Matrix Reloaded, host Stone Phillips stated that the special effects shots were not completely done until three weeks before the release date of the movie.
Trivia: Marcus Chong (who played "Tank" in the original film) was going to return for the sequels, but he was fired before filming began. He was reportedly offered $250,000 to return in his supporting role in both follow-ups (five times what he was paid for the first film), but he refused this offer. He ended up demanding $500,000 up front, plus an additional $500,000 bonus after filming was completed (and allegedly made other demands), after which he was fired. He retaliated by filing a lawsuit claiming that the production had labeled him a "terrorist" and subsequently admitted to crashing at least one press-junket for the films, stealing catering food and prank-calling the directors to annoy them.
