Continuity mistake: Sati and her family leave one suitcase when they get on the train (the one Neo was carrying), but when the train comes back and Trinity steps out, there is no suitcase. It can't have gone anywhere - as we see when Neo tries, the only way out is on the train, otherwise you're caught in a loop. (00:14:05 - 00:24:00)
Continuity mistake: At the beginning of the movie when Trinity and Morpheus first go to visit the Oracle, if you look behind them there are two wooden frames that are on the back wall where Seraph is, then a few shots later they are on the wall where Trinity and Morpheus walked in.

Continuity mistake: In the scene where Neo is talking with the Oracle in her apartment, the Oracle sits down at the table, picks up a bracelet, and right before the shot changes, you can see that it is on her hand, almost to the thumb area. When we cut back to her a second later, the bracelet is back on the table, and she picks it up and puts it on again. (00:26:10)
Continuity mistake: Towards the beginning of the Super Burly Brawl scene (right after Agent Smith gets knocked down on the road), Agent Smith and Neo fly up in the air and collide with each other, causing a massive surge of water to spread out as if a bomb went off. The water then falls back down on the Agent Smith clones, who are now looking up. But if you pay close attention it seems like they are completely dry, despite the fact that they have been standing in the rain and are all soaked. (01:43:50)
Continuity mistake: As the three start to fight at the Merovingian's club: after Trinity snaps there is a shot of Seraph pushing someone down as the man in black pulls the gun on him. To the right, there is a guy who is hurled to the floor by Trinity. In the next shot, Trinity hurls the man again. (00:21:30)
Continuity mistake: Near the beginning when we see Neo walk into the room where the captains, Morpheus, Trinity, and the others are, if you look at Trinity she is standing behind Link in one shot, then he is standing behind her in another, and it is like this for several shots. (00:42:50)The-Immortal
Continuity mistake: During the big rain fight scene between Neo and Smith, Neo punches Smith, who flies into the road making a large dent/scrape. In the next shot, when they are flying above the road, the damage is nowhere to be seen. No other damage is repaired throughout this fight. (01:43:40)
Continuity mistake: In the final battle Neo/Smith scene, when Smith crashes Neo into the ground, the crash causes several cars to fly. When all the Smiths head to the hole to watch, the overturned cars are gone.
Continuity mistake: At the start, When they're running a search for Neo in the Matrix, Morpheus' arms keep switching. For example, in one of the closeups, his arms are by his side, when in the previous shot it's rested on his chin. And when that guy comes in and says 'Sir, I've got the projections,' his arms are folded.
Continuity mistake: When Trinity, Morpheus and Seraph go to see the Merovingian in his club, there is a fight scene before they enter the club. When Trinity kicks the guy at the end of the fight scene, the guy has his arms by his side. In the following shot they are now outstretched. (00:17:00)The-Immortal
