Audio problem: When Neo, Morpheus, and Trinity are meeting the Merovingian, he starts talking about French wine and the language. When the shot changes to behind the Merovingian, he is seen talking, but his mouth never comes close to the words we hear. (01:01:55)
Continuity mistake: When Morpheus, Neo and Trinity arrive at the Merovingian's, the door keeper says "Follow me". The reflection in Morpheus' glasses shows the man still standing there, but in the next shot he has already started walking away. (01:03:30)
Continuity mistake: When we see Neo stop all the bullets that the Merovingian's henchmen have just fired at him, Neo proceeds to let them drop on the floor where they are clearly visible. Yet just seconds later when all the Merovingian's men come running at him the bullets have all disappeared. (01:13:35)
Continuity mistake: In the fight scene in the mansion, when Neo stabs the guy's hand with a sai, his hand is in the top part of it, but when the shot cuts his hand's now a) in the bottom half, and b) free of the sai anyway - he's just gripping the sword which is in the bottom half, with nothing trapping him. (01:15:20)
Continuity mistake: In the scene where Neo fights the Merovingian's henchmen he plunges a sword into one of them and pushes him off the balcony and jumps with him. The body falls near an already dead henchman. In the next shot when the others jump off the balcony the body with the sword is away from the first body. (01:16:00)
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)
Continuity mistake: At the beginning of the big chase scene we see Trinity, Morpheus and the Keymaker in a car going down a street. If you look out the front in one of the shots, they are nearly at the end of the street. A few seconds later they are approaching the end of the street again. (01:19:55)
Continuity mistake: In the shot taken above the Twin's right arm just before the SUV smashes the trunk off the BMW we see that Trinity's Cadillac already made a left turn and is about 70 feet away. In the shot made from inside the SUV just after hitting the BMW, the Cadillac is still taking the turn and seems stuck on the sidewalk. The SUV is about to pass it to the left. (01:20:10)
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: Near the beginning of the freeway chase scene, we see the twins take aim at a gold Chevy SUV. First of all, the first head on view we see of the SUV it has it's Daytime Running Lights on, the next time we see this view they are off. Secondly, one twin shoots out the passenger window and completely shatters it, however after the scene cuts briefly back to the twin it returns to the SUV just as it begins to flip and we see the window shatter yet again. (01:22:05)
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)
Continuity mistake: In the freeway chase, just after the brown 4x4 flips over, one of the twins is shooting at Trinity's car. In a shot from the front his head's well above the sights, and he's spraying bullets around a bit. From behind him, he's holding it tight into his shoulder and keeping his fire in one place. (01:22:15)
Continuity mistake: When Neo finds himself lost outside the castle in the mountains, he calls Link with the cellphone. He then closes the phone panel and the cellphone disappears on the next shot. (01:22:35)
Factual error: During the freeway chase scene, the albino twin appears in the back seat of Trinity's car next to the Keymaker. Morpheus points his gun at the twin and the twin whacks it out of his hand. The gun lands on the car's automatic transmission stick, and you can see the stick is locked in position "2", not in position "D" as would be normal for driving in any other condition than up or down a very steep slope at greatly reduced speed. There is no way Trinity could've run at the speed she appears to achieve on the freeway with her transmission locked into 2nd gear. (01:22:50)
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)
Revealing mistake: In the freeway chase scene when one of the agents jumps onto the hood of the first car then jumps off, the car flips, then a second later as the car is still flipping you can see the gas tank and transmission have been removed. (01:23:45)
Revealing mistake: On the freeway chase, when the agent jumps on the bonnet of the car and it flips over, check the underneath. There is no exhaust pipe and a reinforcing frame runs either side of where it should be. (01:23:45)
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 Trinity is driving through the tunnel leading up to the highway, the action goes into slow motion and Morpheus shoots out the Albino Twins' Escalade SUV driver side mirror to pieces. In the scene where one of the Albino Twins morphs back inside the Escalade SUV on the highway, in which they say "We are getting aggravated", "Yes we are", you see the full driver side mirror intact. It is gone again in the next scenes showing the driver side mirror. (01:24:50 - 01:28:00)
Other mistake: During the beginning of the freeway chase scene, a "Maximum Speed 65" sign can be seen along the freeway wall in the slow lane that is facing the opposite direction of traffic. Freeway traffic in that lane would only be able to see it in their rear-view mirrors. (01:25:20)
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.
