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: After one of the agents rips the roof off the car on the expressway, there are some shots that show the interior of the vehicle still dark as if the roof were still intact.
Visible crew/equipment: In the scene near the beginning of the film where Morpheus is discussing the machines tunelling down to Zion with the other captains, you can see the camera in the reflection of his sunglasses in multiple shots. (00:06:50)
Continuity mistake: The wound and the sleeve of the jacket on Trinity's arm changes after she's cut by one of the twins. When she's cut, the wound and rip in the jacket are thin and diagonal. As Morpheus is calling Link, the wound is not really visible and the cut in the jacket is now larger and squarer, and has changed direction on her arm. (01:21:00 - 01:22:50)
Continuity mistake: In the scene where Trinity, Morpheus, and the Keymaker are standing on the bridge, Morpheus says "Trinity, get him out of here." Trinity then grabs the Keymaker and they both jump off of the bridge onto a truck. Then, when the car the twins are riding is heading toward Morpheus, you can see that there are guard rails on both sides of the bridge, however, next when Morpheus cuts the tires on the car the twins are riding with his Katana, the camera cuts a side shot of the bridge, and one side of the guard rails on the bridge has mysteriously disappeared. (01:29:30)
Continuity mistake: At the start of the freeway chase scene when the agent gets out of the police car, there is a far away shot, and if you look at the bridge behind there is a white van that changes positions on the bridge during shots. (01:23:35)
Continuity mistake: In the scene where Link unplugs Morpheus from the Matrix there is a close-up of Link with Morpheus opening his eyes at the bottom of the screen. In the following two shot, Morpheus still has his eyes closed and opens them up moments after he had already has awakened.
Revealing mistake: After Neo has knocked out the first two agents after the meeting scene, he kicks the last one into the pole of a streetlight. When the agent falls to the ground, he moves his arms from a position where he could brace his fall to one where he could protect his face from the shattered glass that comes directly after when the glass from the streetlight falls and breaks in front of him. (00:09:10 - 00:10:00)
Visible crew/equipment: After the agent crushes the Oldsmobile, look inside and you'll see air cannons and a roll cage.
Continuity mistake: During the freeway scene, the Twin shoots a black car directly in front of Trinity's car. He shoots on the hood and then a trail of holes are seen going up the windshield. The next shot is one from inside Trinity's car between Trinity and Morpheus, but no bullet holes are in the car ahead.
Continuity mistake: DVD version. In the 100 Smiths scene, a woman enters the courtyard and drops a shopping bag. The first shot shows two tomatoes falling out, one hurtling toward the camera out of the shot and a small box falling out of the bag. In the next shot of the ground, you can see several tomatoes and the box is back in the bag. (00:52:55)
Continuity mistake: During the freeway chase, when the car is crushed by the agent, look closely and you'll see a white Monte Carlo land on top of a mini-van. About 30 seconds later you see the same thing, but up close.
Continuity mistake: In the car chase during a few scenes, the number plates on the truck, Trinity's car and the police cars seem to have no registration numbers.
Continuity mistake: At the beginning, Agent Smith approaches the metal door. On the wall to one side is the writing "Muz 25", on the other side a wire ends in a light switch. After the fight, Neo kneels in preparation for flight and the light switch has vanished. (00:08:10 - 00:10:45)
Revealing mistake: During the fight against the Frenchman's men, at one point a giant stone statue is broken, falls over and smashes apart. You see it hits a stone railing on the stairway, which wobbles and makes it very clear that the statue is a breakaway, unlike the rest of the set. (01:18:45)
Audio problem: On the freeway when the Twin stops firing when the car goes behind a truck (shortly before he floats into the car), you can hear about 5 shots being fired by him after the muzzle flashes stop and the gun stops shaking. (01:22:15)
Visible crew/equipment: In the freeway chase, an agent jumps on the bonnet of the car which we then see flip. In the side view when the doors fly open we can see the strengthening frame, gas canisters, etc, inside the car which create the effect. (01:23:50)
Continuity mistake: When the Keymaker opens the door inside the white corridor near the end, you see in the reflection on the doorknob and it shows the corridor, but it does not have any doors in the reflection and there is a white door behind the Keymaker, which you cannot see otherwise when you look in that direction.
Revealing mistake: In the highway chase scene, Trinity, Morpheus, and the Keymaker pull off onto an exit and the twins follow. If you look closely at the exit and the overpass, you can see that it ends after it goes over the highway. The exit/overpass goes nowhere. You can see this during the various shots when Morpheus faces off against the twins and later when Trinity looks back at the overpass from on top of the Ducati carrier.
Continuity mistake: When the operator on the Vigilant is impaled, at first the bar seems to be coming out of his chest horizontally. When they show him again later as the ship explodes it seems to be pointing much higher up.
Answer: This was made just for the trailers. The same part (without the Matrix code) can be seen when Smith says "suprised to see me?" to which Neo replies "No." and puts on his sunglasses before the Burly Brawl.
