Continuity mistake: On the freeway, the rear lights on Trinity's bike are sometimes on and sometimes off. And, no, they're not brake lights because they're on at the start when she is accelerating away from the lorry that is transporting the bikes. (01:30:35 - 01:31:40)
Continuity mistake: In the freeway scene, Morpheus fights an agent. Right before Morpheus gets knock off onto Niobe's car, you see Morpheus land and lose his balance on the left side of the back of the truck, but when there is a shot of Morpheus falling off the truck, he is falling off the centre. (01:34:55)
Visible crew/equipment: You can see camera equipment in the reflection of the sunglasses on the agent that takes over the tractor-trailer truck. (01:35:50)
Revealing mistake: When Agent Smith stands in the way of Neo, Morpheus and the keymaker, Smith's glasses reflect an empty corridor when 3 people are right in front of him. (01:41:45)
Visible crew/equipment: In the scene where Morpheus is sitting in the chair near the end of the movie giving his "War and fate" speech you can see the microphone and camera in his sunglasses. This is repeatedly seen during the whole scene. (01:43:00)
Continuity mistake: In the scene where Trinity is typing the 'disable grid nodes 21 - 48' command, she is pressing random keys rather than the correct sequence. The text already on the screen in the beginning of the next shot is 'disable grid,' but the 'G' key is one of those that have not been pressed, whereas 'H', for obscure reasons, has been. (01:43:35)
Other mistake: In the scene where Trinity tries to deactivate alarms in the building she types "disable grid nodes 21-48". Then a warning appears on the screen of her laptop which says: 'Disabling nodes 21-48 will disconnect sector 11 (27 nodes)'. However, because of the fact that nodes 21 and 48 are both included in the range, the total number of nodes to be deactivated is 28 (not 27 as written on the screen). (01:43:50)
Continuity mistake: Near the end of the film when we see the Keymaker open the door and Neo kicks Smith to make a gap, if you look where Neo is, there are two Agent Smith's behind him, they are looking towards Neo's direction and pulling there guns out, yet when the shot changes to a close up, the two Agents are facing one another and then pull there guns again. (01:44:10)
Audio problem: After the Keymaker has been shot, Morpheus and Neo rush to him and turn him over. The Keymaker's gasping for air is very audible, but the first reflection of him that we see in Morpheus's sunglasses shows that his mouth is tightly closed. This is only visible in that one reflection shot. (01:49:00)
Continuity mistake: During the freeway scenes, the katana Morpheus used as a foot hold to grab the keymaker keeps moving. It was at arm's length from the top when he inserted it; when Morpheus was standing on it, the sword was a whole body length below the top; when Morpheus took the sword out in his fight against the agent, it was back in its original position.
Continuity mistake: In the car chase scene, when Trinity is driving the cadillac, the Agent in the cop car slams into the driver's side of Trinity's car and the driver's side mirror is bent inwards. When Trinity drives the cadillac onto the exit ramp, the driver's side mirror is back in its normal position.
Continuity mistake: During the car chase, the twins shoot out most of the windows in the car that Trinity and Morpheus are driving in. But every time they cut to a shot of them inside of the car, the windows are intact and there is no shattered glass to be seen.
Continuity mistake: Trinity's cut on her right arm disappears and reappears throughout the freeway scene.
Continuity mistake: In the highway chase scene there is a shot of the police cars before they get onto the highway and the cars are Chevrolet Caprices. When they are on the highway chasing Trinity's car, the police cars become brand new Chevrolet Impalas. But when the police cars start to ram her, they become Caprices again.
Suggested correction: There were 3 police cars; two Impalas and a Caprice. The police car possessed by the agents was always a Caprice from the beginning. One of the Impalas rammed into the black Oldsmobile Intrigue which was shot and flipped by the twins and the other Impala disappears after the massive crash scene (probably crashed within the mayhem).
The Impalas were ahead and the Caprice was behind in the tunnel before the highway. Right after the highway scene (when the CTS Swerves between two trucks) however, you can see 5 cars (one Caprice and three Impalas, and one unknown car ) but after that it's back to 2 Impalas and Caprice. So the mistake is three cars turning into five, not the switch between Caprice and Impala.
Continuity mistake: When Neo and the keeper are fighting on the middle bench, one by one the bowls get knocked off - the two on the far corners (left and right) reappear and disappear at least once. Likewise the pot on the right hand table with stick-like things in - that table's completely cleared at one point, but that pot reappears.
Factual error: In the scene where Neo is shot at by the French guy's henchmen, they shoot with different types of guns. 4 of these are submachine guns which would fire 9mm. Another is a M1928 Thompson would fire .45 APC. Lastly there is a Heckler and Koch G36K which would fire the drastically different 5.56x45mm NATO. When Neo stops the bullets, they are all 9mm Parabellum rounds.
Continuity mistake: Further to the comment about some of the Smith clones not having Hugo Weaving's face pasted onto them, just after Neo does his back flip into two agents whilst kicking the two either side of him, just after he turns back around towards the camera, there is a very obvious stuntman standing just behind him who looks absolutely nothing like Agent Smith.
Continuity mistake: When the twin leaves the car that Trinity is driving, he is standing on the freeway by himself. You see a flat-bed truck, then a police car, then a red van pass him by. But when they show the shot ahead of him, the truck is still there, but the cop car and the red van are nowhere to be seen.
Continuity mistake: In the car chase scene when the Twin enters the car with Morpheus, Trinity and the keymaker the camera view changes between aerial shots and shots from in the car. In the aerial shots the road behind them is completely empty. From the shots in the car you can see several cars behind them through the windows.
Revealing mistake: During the freeway scene, if you look closely, you will notice that some of the trucks have no axles. Most obvious is the second one the camera goes under when following Trinity on the bike.
