Continuity mistake: The two backup judges have just arrived and are asking to be let into Peach Tree. Mama has a knife on the tech guy's stomach, coercing him to keep the blast door shut. In every shot from the behind, her left hand has a firm grip on the guy's shoulder. In shots from the front, the hand is absent. (00:55:00)ployp
Continuity mistake: There is a shot which is used twice: when Dredd comes out of the elevator on his way to the Med Center and shoots someone from cover. It is used again when he and Anderson are on level 200 clearing the last of MaMa's henchmen. You can tell by the elevator buttons, the awkward sudden shifting of Dredd's position in relation to the door and the continuity with his gun suddenly going from unsilenced to silenced and back.

Continuity mistake: During the firefight in the large square room, the blood of all the criminals is bright red. After Anderson executes the last criminal, the camera shows us a wide shot of the room with all the bodies. The blood is now a deep brown color.
