Trivia: The actor who plays Cas is the real-life wife of Laurence Fishburne, Gina Torres.
Trivia: When Neo, Trinity and Morpheus arrive at the Merovingian's restaurant, the camera pans left oddly from the main table to show a man walking away, looking over his shoulder at Neo. This man is the father of Seti from Revolutions. Kind of interesting, since in Revolutions, the father mentions his meeting with the Merovingian.
Trivia: Has anyone noticed how when Neo gets yelled at by his boss in the first film, his comments are relevant to the first film and this one? Neo has to make a choice whether he wants to keep his job (stay in the matrix )or leave (be freed from the matrix), that he believes that he is special, that somehow the rules don't apply to him, and then he says, "Obviously you're mistaken." The architect said something like, "If too many started to having doubts about if their world is real, the matrix would break down and they had to start over again." This is more or less exactly what his boss says to him in the beginning, when he mentions something like how this is one of the world's greatest software companies because every single employee is part of a whole. And if one of their employees has problems then so does the rest of the company.
Trivia: If you have seen "Crouching Tiger, Hidden Dragon", pay attention to the fight between Neo and the Oracle's Chinese bodyguard. It has the same exact hits, shots and music of the first fight of CTHD (it is especially obvious when we see both men's legs almost like dancing). A tribute from the directors?
Trivia: Anyone who was a big fan of the 60's TV show, The Prisoner, will see certain similarities between that and Neo's encounter with the architect. This is probably intentional since, in the first movie, an episode of the Prisoner (with Number 6 ever so appropriately meeting number 2) is playing in the background.
Trivia: In the scene where Neo first meets and sits down with the Oracle. When the camera is behind Neo and Oracle, looking over their shoulders between them, you see a tall, brown fence across the plaza. On one side is written '1300,' on the other is written 'One or 'Neo' (I can't remember which), both in large, white letters. You see '1300' spray-painted on at least three different walls in various ways. First, '1300' is the military time for 1:00, or just one. It is also the year that Dante started his entry into hell in the Inferno. He begins the Inferno with, 'Midway through life's journey I wandered into a dark wood.' The Biblical life's journey lasted 70 years, and since Dante is believed to have been born in 1265, midway through his life would have been the year 1300. Second (and this is really creepy), you will notice that just after Agent Smith shows up, various scenes show that the 'One' or 'Neo' on the same fence as '1300' begins to fade over the next three shots until it completely disappears. It is shortly after the last shot, which shows that Neo's name is gone completely, that Agent Smith starts talking about the possibility that something in Neo got 'written over' something in Smith or vice versa. It is as if Smith's mere presence is trying to over-write Neo's presence, by eliminating him first from their surroundings. I was not able to tell, but I tried to see, after Neo successfully pulled Smith's hand out of his chest, whether Neo's name showed back up on the fence. But I couldn't tell.
Trivia: When the dance starts at Zion, the camera zooms in to show two drummers. The one on the left is Arion Salazar, the bassist for Third Eye Blind.
Trivia: During the entire freeway chase, almost every vehicle was GM made. GM donated about 300 cars for use in the film. By the time filming was finished, almost all of them were wrecked in some way.
Trivia: When the Architect is talking about all the people that will die in Zion, there are clips from TV commercials and other movies on the screens beside/behind him. Among them is a famous black and white clip from Alfred Hitchcock's 1960 film "Psycho".
Trivia: The 'twin' characters are non-film actors, but carpenters by trade, whose only other screened work was on UK TV programme Carol Vorderman's Better Homes (DIY show). They have done some stunt work, but got the part when the makers of the film were looking for identical male twins who were both skilled in martial arts.
Trivia: Near the beginning of the freeway chase the car containing Morpheus, Trinity and the Keymaker and the van containing the superb "Twins" pass a billboard. This billboard is advertising steak. Steak was the meal Cypher ate with Smith in the first film. Also if you watch until the end of the credits of the first film you will find that the password for the website www.whatisthematrix.com is steak.
Trivia: In the highway chase scene, the license plate on the Twins' truck said DE2852. If you look in Deuteronomy 28:52 (NIV), it says, "They will lay siege to all the cities throughout your land until the high fortified walls in which you trust fall down." This is possibly making reference to the sentinels coming to attack Zion, which up until the end of Reloaded, has been the humans safe haven and their "high fortified walls" against the machines.

Trivia: One night on the 2 mile stretch of highway made for the movie, a security guard decided to race his car up and down when no one was around. He did, but he totalled his car and instead of telling anyone, he just ran off and was never seen again. (A little bit of info from Keanu Reeves on an interview on the Tonight Show).
Trivia: A freeway was built on a military base in California specifically in order to film the freeway chase scene. It was built as a continuous loop that is about 2 miles of freeway. This also explains why you see some of the background repeating.
Trivia: The "code" in the matrix consists mainly of both Western numbers and the Japanese katakana writing (a Japanese script used especially for foreign words). Both were mirrored vertically.
Trivia: Towards the end of the freeway chase when the Agent takes control of the truck, the suspenseful sound effects that play in the background are almost identical to those used in the famous truck chase in Terminator 2.
Trivia: In the scene where Trinity is fighting the agent in the building having just disabled the grid, when she is fighting and throughout the entire movie there is no visible place to store a gun or two guns as big as the ones she pulls out as she falls down the building, in such a tight suit. (01:17:35)
Answer: This was made just for the trailers. The same part (without the Matrix code) can be seen when Smith says "suprised to see me?" to which Neo replies "No." and puts on his sunglasses before the Burly Brawl.
