Continuity: When Spartan and Phoenix are fighting in the sewers, Edgar Friendly shoots his gun at Phoenix and you see the catwalk that Phoenix was on tip to its side and Phoenix dropping down to the ground with the plank of the catwalk right below him. When Phoenix lands on the ground the plank is nowhere to be seen. It should have been right below him.

Continuity: When Spartan and Huxley arrive at the cryogenics place to battle Phoenix, Phoenix sees them on the monitor walking into the building and you see Spartan on the left and Huxley on the right. The camera angle changes to an inside view and Spartan is now on the right.

Continuity: When Spartan slams the Cryogenic pill on the ground he is about 3 feet in front of Phoenix, but when you see him jump up to grab the claw, he is seen much farther away.

Continuity: When Spartan switches seats with Huxley in the police car, the outside shot shows him get into the back seat. When the shot switches to Huxley in the driver's seat, we can see the back and Spartan isn't seen anywhere in the car.

Continuity: When Spartan drives the car through the glass window, you see glass everywhere. The camera angle changes to a wide shot and you see the car driving away but no glass on the ground.

Visible crew/equipment: When Pheonix falls through the glass at the museum into the LA exhibit, you can see him sliding down a clearly visible safety rope. His feet are even in the position to be sliding down the rope.

Continuity: The guard Phoenix throws through the glass case has on footwear which resembles socks. As he is smashing through the glass, he has on heavier leather boots.

Continuity: During the final fight scene, Spartan grabs Phoenix and they land on top of the ice block and roll off in front of a few metal jugs. The camera angle changes to a close up and the jugs are not there anymore as you see Spartan punching Phoenix.

Continuity: During the first fight scene between Phoenix and Spartan, Phoenix sticks his knife into several barrels of fuel and you see the fuel all over his knife but when he lays it on the table it's dry.

Revealing: Watch closely as Phoenix is about to fight the cops near the computer kiosk: the same two people wearing white robes pass behind the officer with the hand-held computer twice.

Continuity: When Spartan is frozen, his mouth is open, but when you see him in the block of ice his mouth is closed.

Continuity: In the opening scene as Spartan is getting ready to bungee down to the roof, he kicks a bag out of the chopper that pulls the cord out with it; the bag is never seen in any other shots of the cord as Spartan drops.

Continuity: After Spartan goes through the glass SAPD sign, the car flips over on its roof. But when they show the car up close its now right side up.

Continuity: When Phoenix throws Spartan over the bonnet of the red car in the museum, Spartan lands in a puddle that soaks his hair. In the next few shots, the hair keeps changing from being soaked to being dry.

Continuity: When Phoenix blows up the door sealing the Armory, it is just about the size of a normal door, but when he runs through it to escape into the main hall, the door is four times larger.

Factual error: During the fight in the museum, Spartan gets three shots out of a shotgun which only holds two shells.

Continuity: When Spartan is hunting for Phoenix at the Cryogenics lab, the 2 scratches on his face appear and disappear throughout the scene.

Continuity: When they are in the Cryogenics lab, the tear and blood spot on Spartan's shirt changes throughout the scene.

Continuity: Several times during the movie, Simon Phoenix's shoulder pads (one side resembles an ATV tire) switch sides.

Continuity: During the scene where Phoenix is questioning the leader of the future society in his office, he says at least one word (hell) that he should have been fined for, and isn't. We see that there is a ticket printer in the room in a later scene, when Savage sets it off during his own confrontation.
