In the scene where Neo fights Agent Smith on the road with all the other Smiths watching in the line, there was so much rain falling that Keanu and Hugo had to wear wetsuits under their clothes and could almost never see what they were doing.

In greek mythology Persephone was the wife of Hades, ruler of Hell. Persephone is the wife of the Merovingian, ruler of the Hell Club.

In the credits, the source (the big machine head that speaks to Neo) is credited as "Deus ex machina" which means "a god from a machine." In ancient Greek and Roman dramas, a deus ex machina referred to a god lowered by stage machinery to resolve a plot or extricate the protagonist from a difficult situation.

When Neo dies, the matrix "mouth" says "It is done." Those are Jesus' last words before his death and resurrection.

The Kid (the boy who opens the gate after Mifune dies) is one of the few side characters that has a background. In the 'Animatrix' episode 'Kid's Story', It is possible to learn how he got out of Matrix and understand what Neo means in Matrix Reloaded ('you saved yourself').

One of the bouncers at Club Hell calls Seraph "Wingless." A seraph is an angel with 6 wings, mentioned biblically in Isaiah 6.

Additional "Jesus" references: 1) when the surge of power goes through Neo's real body as his Matrix self is assimilated, it forms a plainly visible crucifix shape across his torso and outstretched arms. 2) In the long view of Neo's body on the barge as it is borne away, when it switches to the fiery "alternate vision" the machines' tentacles form a very angelic outline.

The cat that appears at the end when Sati wakes up is the same cat that was in the first film when Neo said he had a case of deja vu. It even shakes the same way when the matrix changes.

The Jesus references keep coming, because after Neo leaves the Logos, we see what he sees. When he's walking towards the opening, he looks down and sees ripples going from his feet, almost as if he was walking on water.

Just before the images of matrix code at the beginning of the movie settle on the orange "Explosion" you can see the code form a small bulls head. It's a nice nod to Chicago, the Wachowski brothers home city. Plus their home NBA team, the Chicago Bulls.

Neo's journey to the machine city and subsequent battle with Smith has many parallels with the new testament. Firstly, when he and Trinity fly over the clouds it mirrors the ascension of Christ into heaven. Secondly, Neo walking along the gangway where he is confronted by the Deus Ex Machina is similar to St. Paul on the road to Damascus where he was confronted by God, and lastly Neo's fight with Smith is effectively Armageddon battle of God against the devil, and leads to the end of one world and beginning of the next.

Gloria Foster, who played the Oracle in the first two Matrix movies, passed away two years ago (September 2001), forcing an explanation for the change of appearance in this film.

A lot of people bemoan loose endings in this, but in part that's probably down to this movie, more than any other on this site (hence barely qualifying this as trivia), attracting utterly inane submissions, listed here for the amusement of people who've actually paid attention to the other two films. Firstly, at no point in either of the movies does anyone say that they've "destroyed the sun", which would have resulted in an error when they fly above the clouds and see it, as at least three people have submitted. They scorched the sky (ie. caused heavy cloud cover). How are you supposed to destroy the sun? Nor did anyone say that Zion was destroyed at the end of Reloaded - the battle which only Bane survived was the attempted EMP-based ambush of the machines within the tunnel system. And finally, Niobe didn't die in Reloaded - don't know where anyone got that idea from. Keep an eye on this entry for more daft submissions - I do wish people would pay attention sometimes...

According to John Milton's poem "Paradise Lost," Satan was once a very powerful angel named Lucifer until his pride got the best of him and he tried to take God's throne. A war raged in heaven, and Lucifer was cast down to the earth as Satan. Agent Smith was once a powerful agent who served the source (Deus ex Machina, God) until he chose to fight the system.

At the end of the movie where the Oracle is talking to the Architect, there is a plaque on the bench she is sitting on which says "In memory of Thomas A. Anderson".

Several things in the movie relate to the video game 'Enter the Matrix.' Two examples are when Niobe says she saw the Oracle right before the EMP was fired from the Hammer. One of the video game's cut scenes are when Niobe and the Oracle have a meeting. Niobe also mentioned when she was cornered by sentinels. You get to play that level in the game where you are being chased by the sqiddies. Also in Reloaded when the power plant is destroyed, that is also one of your objectives in the game as Niobe. The Trainman and Niobe also have a brief encounter in the game. There are many other examples, but you need to play the game to find them out.

The actor that plays "The Trainman" also appears as one of The Strangers in the similarly themed film "Dark City."

The Oracle never breathes out any of the smoke from her cigarettes, even when she talks immediately after having a drag. Fake cigarette or part of the Oracle's mystery? Either way it's almost certainly a reference to the ancient Greek Oracle at Delphi, where the Pythia would engage in a ritual that involved inhaling laurel and barley smoke before giving her prophecy.

The idea of Neo becoming blinded and then being able to "See" life force is identical to a major plot event in "Dune Messiah", Book 2 of Frank Herbert's Dune. The major character with god-like powers is struck down and blinded through betrayal, only to reveal later that he can still see but in a whole new way.

The Oracle smokes 'DOUBLE DESTINY' brand cigarettes.
