Continuity mistake: When Phoenix first gets out he makes his way to a computer and the police come to arrest him. Phoenix takes one of the policeman and pushes his head through the side glass pane and walks away to fight the other officers, but when Phoenix goes back over to the computer the glass is not broken.

Continuity mistake: When Spartan is initially frozen in the cyro-liquid, air bubbles and ripples are in the ice around his mouth. Any following shot of him in the ice block shows no bubbles or ripples. (00:10:15)

Continuity mistake: When Spartan is swearing at the verbal morality machine and pulls out several citations at once (the last ones he grabs), an actor and actress standing directly behind him start to walk away and go off screen to the right behind Spartan.

Continuity mistake: When Huxley, Spartan and the other guy get in the police car to go to the museum they are all wearing sunglasses. In the very next shot all three are not wearing them.
Continuity mistake: In the opening credits when Spartan is frozen, both hands are up either side of his head. In the very next shot his left hand is by his head, but his right arm is out stretched and in a down position, impossible as he is frozen. Also his mind altering sensors are on the left side of his head and body before freezing, next shot they are on the right side of his body.
Continuity mistake: When the Cryo-Prison worker opens the cabinet that holds the cylinders that contain the blue "freezing balls" to freeze Spartan's slush, the slot on the center left is empty. When the shot changes to the worker pulling the cylinder out, the slot to the lower left is now the empty one. (00:09:45)
Continuity mistake: During the Oldsmobile dealership scene two robed citizens are shown to be looking at small scale model cars on the rear wall (blue car) and side wall (red car) in the showroom. When Huxley and Spartan bust through the floor in the elevator the two citizens are missing. (01:30:50)
