Continuity mistake: When Matrix shakes the phone booth at the mall, the hole on the glass increases / decreases randomly. (00:36:00)
Continuity mistake: During the fight at the end of the movie between Matrix and Bennett when Bennett calls Matrix a "dead man" and he responds with "Bullshit" you see him come off the wall with his left hand. He is throwing a left hook, but in the very next shot when the punch comes in contact with Bennett his fist is going from right to left in a backfist motion, rather than a left to right hook. (01:23:45)
Continuity mistake: Right when the fight between Matrix and Bennett begins, the Uzi submachine gun vanishes from Bennett's right shoulder (it was on a strap). Then suddenly at the end of the fight (after the fell down over the railing and to the next level down, the Uzi reappears when Bennett picks it up and attempts to shoot Matrix. Bennett lost it on the upper level nowhere near the railing, and it somehow appeared on the lower level away from the railing.
Factual error: When Matrix escapes from the landing gear of the plane, he opens a hatch to access it, but doesn't close it behind him. This would have later led to the cabin depressurizing and the plane plummeting to the ground.
Revealing mistake: When Matrix reaches Arius' mansion (in actuality the Harold Lloyd Estate), he is rushed at by several soldiers of Arius' private army and starts shooting at them with his RPK. In one shot from Matrix's rear we can see him shooting four soldiers at the same time. However, the two soldiers on the far left drop dead even though Matrix is aiming his weapon to the right. (01:11:40)
Continuity mistake: While eating sandwiches, Matrix's daughter says, "You don't wanna know" as she reaches for a napkin. A frame later, from a different angle, her hands are empty as they reach for the napkin. (00:08:20)
Continuity mistake: During the machine gun scene at the en Matrix has a belt fed M60 machine gun. When the fight starts, he has plenty of bullets. A few seconds later he has about 20 cm length of the bullet belt left. Scene switch - and he has more bullets. This switch between low and high ammo a few times. (01:16:15)
Continuity mistake: When the thug meets Cindy by the public phones, him and the people behind her (lady in pink and man in green) drastically change positions between the first and second shot. (00:25:50)
Other mistake: Matrix enters his house through a door on the penthouse and a dead soldier by the edge collapses. His feet and legs should be blocking the door and the entrance, but instead, from the angle inside, it swings freely. (00:13:20)
Continuity mistake: When the military guy leaves Matrix's house, the chopper's shadow points in a 12 o'clock direction. A frame later it's pointing to 3 o'clock. (00:11:25)
Audio problem: The post-production beep sound-fx coming out of Matrix's stopwatch is sometimes on and others off. (00:22:05 - 00:44:05)
Suggested correction: No, it wouldn't. The entire wheel well of an airliner is pressurised - otherwise the tyres would explode! Once the undercarriage is retracted (typically at less than 1000 feet) the pressurisation problem no longer applies. Plus, the access door opens inward (like most aircraft doors), so the pressurization would force the door shut against the frame anyway.
Wheel wells of airplanes are not pressurized. Airplane tyres are about 145PSI at ground level, and at altitude they'd be under 160PSI, nothing radical for tyre manufacture. Plus as the air temperature decreases at higher altitudes, the tyre cools and the internal pressure drops, more than compensating for the lower external pressure.
Wheel wells of airliners are always pressurised. Those stowaways who hide in the wheel wells die from hypothermia or are crushed to death by the retracting undercarriage. They do not suffocate.
