Continuity mistake: When Harris is briefing the new group for the first time, Hightower loosens the leg of Harris' chair so that it breaks when Harris sits down. When Harris gets up from the middle of debris, the next shot shows an innocent looking Hightower and the chair is intact in front of him.
Continuity mistake: When Commandant Lassard and Sgt. Fackler enter the bar, Lassard plays pool with one of the customers. Lassard pockets the 9-ball two times between the shots, even though it is the same ongoing game.
Continuity mistake: When Hightower emerges from the pile of rubble he has dust on his shoulders and arms, but when he walks up to the bad guy the uniform is as good as new.
Continuity mistake: Does the poisonous gas seem to clear out of the room where Sargent Lasard is trapped in too quickly or what? They were only outside for a couple of seconds and then when they enter the room its as clear as can be, as if nothing had happened.
Continuity mistake: The picture of Cpt. Harris in the newspaper in the beginning is different than the picture that was taken. When his picture is taken, he's holding the tail so it forms a U-shape. In the newspaper, the tail is in a different position and his eyes are opened wider.
Continuity mistake: The gang shoots the mastermind's screen with a plastic dart, but a few moments later the dart has vanished.
Suggested correction: Those little rubber darts don't stick to everything. Could have fallen off.
Continuity mistake: When Harris is hanging off the side of the window washing rig and grabs Proctor's hand, Proctor is straddling the railing and reaching over with one hand and the other hand is holding onto the railing. But as Harris grip starts to slip, there's a shot of Proctor where's he's not straddling the railing, he's leaning over it with both arms grabbing Harris. In the next shot he's back to straddling the railing.
