Continuity mistake: Close to the end of the film when some of the people from Zion are trying to blow the legs off of the diggers, in one particular shot you can see that they only load the right side of the rocket launcher, but in the next shot both sides are loaded. (01:03:00)
Revealing mistake: During the battle of the dock, just before Shara takes her second shot at the digger, she is seen from behind as her weapon is being loaded. As Zee is about to slide the rocket in, the green screen is momentarily visible through the barrel. (01:05:35)
Continuity mistake: When the Logos plummets from the sky and crashes into the machine tower, Trinity is skewered with cables. In slo-mo you can see that at least two cables penetrate her upper chest, but when Neo is lying next to her a minute later the cables have impaled her below the ribcage and there are no chest wounds. (01:32:20 - 01:33:45)
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: 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)
Revealing mistake: When Neo and Smith are fighting at the end of the film - when Smith knocks Neo into the rafters of the room they are in, you can see Neo's face, and it's obviously Keanu Reeve's stunt double. (01:44:30)
Visible crew/equipment: When Smith and Neo are fighting in the building Smith is knocked to the floor. When he gets up you can see the stage light in his glasses. (01:44:35)
Revealing mistake: When Neo kicks Smith through the window, if you look carefully you will see that it is a stunt double. (01:46:05)
Visible crew/equipment: As the Oracle stands up from the bench, right at the end (after she says "Someday"), you can see a strip of yellow tape on the back of the bench marking the right place for her to sit. (01:54:40)
Continuity mistake: When Smith is finally destroyed there is a wide shot and a close shot of the Oracle lying in the water filled crater. In the wide shot, there is a lot more water; her arm is completely underwater and so is half her face. In the close up, her head is almost entirely above water and her arm is visible. (01:55:00)
Continuity mistake: When Trinity dies, the blood behind Neo's right ear keeps appearing and disappearing between shots.
Continuity mistake: At the very end when Oracle is sitting on a park bench, she and Sati look at the sunrise between some skyscrapers. About a minute later, there is another shot of the sunrise, but in this shot the skyscrapers are considerably shorter.
Revealing mistake: In the scene where Captain Mifune is defending a bridge, alone, and commands "reload", he put the right arm of the APU straight, revealing in the background some sparks that floats independent of the action and stops for a few moments.
Revealing mistake: In the subway scene, when Neo gets slammed towards the wall (and crashes into it) it's visibly Keanu's stunt double.
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.
Revealing mistake: During the fight for the dock, after the first APU calls for a reload, Kid is seen in an ammo bay right before a fellow ammo runner is being sent out. As the door opens, a sentinel attacks them and all of them react surprised, except the ammo runner and the guy standing next to him, who don't react at all.
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.
Revealing mistake: During the scene with Deus Ex Machina, see carefully the shot when Neo says "I won't" you will see two strange horizontal lines going down; visible specially on the left side of the screen. They are visible in the trailer too.
Continuity mistake: In the final fight between Neo and Smith there is one shot of Smith's legs running towards Neo and one shot of Neo's legs running toward Smith. In those shots you can see that they are not running against each other.
Continuity mistake: When Neo gets up in the final fighting scene with Smith after he says 'You're right Smith, you're always right,' his hair is pushed back from the rain and mud. In the next Neo shot, it's down over his forehead.
Answer: In the first film she points this same sign out to Neo and explains that it means "Know Thyself"
