Monica Bellucci's dress is some what see-thru. You can see that she isn't wearing underwear.

In the highway chase scene, the license plate on Trinity's car says DA203. If you look in Daniel 2:3, which says "he said to them, 'I have had a dream that troubles me and I want to know what it means.'" This is possibly making reference to Neo's dream, because he went to the oracle partly to figure out what his dream about Trinity meant. The biblical text is speaking about King Nebuchadnezzar's searching for the meaning of his dream. In Verse 3, the Nebuchadnezzar says, "I have dreamed a dream." In Verse 5, when asked to explain his dream, he says, "The thing is gone from me" (all this is from the classic King James Version). Near the end of the movie as the Nebuchadnezzar explodes as a result of the sentinels' bomb, Morpheus says "I have dreamed a dream, and now that dream has gone from me."

In the highway chase scene, all of the signs on the road happen to be cheat codes for the video game, Enter the Matrix.

Trinity uses a real hacking engine to hack into the Matrix. She uses Nmap version 2.5BETA25 to find a vulnerable SSH server and then exploits the weakness using the SSH1 CRC32. If that means anything to anyone.

When Neo meets the Oracle she is feeding crows. The number of crows corresponds to a prediction for the future (appropriately enough). She is feeding 5 crows, the symbol of sickness (of the matrix or humanity perhaps). More crows arrive with Smith and 6 or more is a portent of death.

It may interest any of the fans of Reloaded's female stars to know that, if played correctly, and because it follows the films' sub-plot, the Enter the Matrix game contains a cut scene with a rather steamy kiss between Niobe and Persephone.

Towards the end of the movie when Trinity is actually going into the matrix on the motorcycle to help turn off the emergency power systems, it appears that the liscence plate on her motorcycle said PS352. If you look in Psalms 35:2 (New International Version), it says, "Take up shield and buckler; arise and come to my aid." This could be alluding to how, though he doesn't know it, Neo needs Trinity's help in turning off the emergency power systems so he can reach the door that the keymaker is taking him to, that ultimately leads to the architect.

The visial effects co-ordinator, who supervised the following shot, explained. Trinity falls out of the power station window, while firing at the two agents, who dive out after her. He explained that the shot was done with Carrie Anne Moss sitting in a chair, with her legs stretched out in gynecologist stirrups. A camera on a track ran past and around her, shooting at high speed (so it could be slowed down to 24 fps). The sequence took over 200 shots to complete and was one of the longest non-CGI sequences of the film.

Near the beginning of the film, Agent Smith drives up in an Audi with the license plate "IS 5416". This appears to be yet another Bible reference--Isaiah 54:16--reads as follows (from the King James Version): "Behold, I have created the SMITH that bloweth the coals in the fire, and that bringeth forth an instrument for his work; and I have created the waster to destroy." (Capitals are for emphasis).

The film's cinematographer, Bill Pope, makes an appearance as the 'sleeping security guard', at the power plant.

In the Merovingian's restaurant most of the walls are made of square pieces of glass. Many of the glass squares are images of the vertical falling Matrix code.

When Neo is taken by the agents for interrogation in the first movie, we can see a shot of him in the interrogation room from an array of television sets, which zoom in. That's the same array of television sets from the Architect's room.

The Architect shows Neo images of the humans that will die if Neo chooses not to go into the Source. Many of those images are from the movie "Baraka." A study of comparative religion, "Baraka" contrasts the purity and beauty of nature and religion with the ugliness and misery of modern technological society. The word "baraka" means "odor of the holy," "fragrance of the divine," "saintly," etc. Interestingly, some of the images that Neo sees are of people who were killed in Nazi and Pol Pot concentration camps, as "Baraka" seems to suggest.

Keanu Reeves bought Harley Davidsons for all the stuntmen in the "Burly Brawl".

Agent Smith refers to Neo by name only once in each film. In "The Matrix" when he is interviewing him ("...the other life is lived ... where you go by the hacker alias "Neo" and you are guilty..."). In "Matrix Reloaded" when he knocks the door and says "I'm looking for Neo", and in "Matrix Revolutions" when he says "Everything that has a beginning has and end Neo".

When Neo is meeting the Oracle, as well as when he's fighting the Agent Smiths right after, there are a bunch of words spray-painted on the fence, walls and bench, two of which are "one", spelled upside-down and backwards, and "role", which has to do with everyone having a role, or purpose, to play in and/or outside of the Matrix.

101 is also the number of the floor where the three have lunch with the crazy French dude.

Lachy 'Sparks' Hulme from the Matrix Revolutions can be seen in the council meeting scene. He is sitting two seats to the right of Niobe, but was not credited for this.

At various times in the movie, Morpheus makes a statement relating to dreams. In Greek/Roman mythology, Morpheus was the name of the god of dreams.

Look for a cameo by noted racial scholar and professor Cornel West during the Zion Council meeting (he plays the Council Member who requests that a ship be sent to ascertain the fate of the Nebuchadnezzar).
