Robocop 3 (1993) - 6 major mistakes

Continuity: When the two Ninja robots fight, the robot on the left loses his head before the blade strikes.

Continuity: When Robo gets his arm chopped off by Otomo, he stands up and in Robovision, you see that he needs power, but you cannot see Otomo who is supposedly right in front of him.

Other: Near the end, just before the OCP building explodes, when Robocop flies carrying both girls to get out of the office you can see the wires that make this possible.

Factual error: When Robocop flies through the window of the top floor of the OCP building, the Rehab leader's hair blows around. Being that high up, that is absolutely correct. But after the ninjas appear, there is no longer any wind and no one's hair moves. "Robocop 2" tells us that the OCP skyscraper is sixty stories high. There would be a constant "breeze" with the window busted open.

Plot hole: At the end of the film, the Rehabs recruit gang members and give them all kinds of guns from shotguns, handguns, and automatic weapons. The cops and deputized citizens have similiar weapons. But for all the shooting, not one gang member is hit and only one citizen appears to be shot (aside from the three blown off the building roof by the Rehab tank.) I don't think anyone has any bullets.

Revealing: When RoboCop has his forearm cut off, you can see Robert Burke's arm covered in black material poking out from beind his back. The arm appears again a few times during this scene.
