Audio problem: When RoboCop is being tested in the shooting gallery, he puts his gun away in his leg. But the sound effects for his leg closing are out of sync with the actual movements of his leg. (00:32:55)
Audio problem: At the end of the movie where Dick Jones is falling from the OCP building. At the end of the shot you can hear the splat sound. But he's not near the ground yet. He is still seen up in the air. (01:36:00)
Visible crew/equipment: When Clarence Boddicker (Kurtwood Smith) is killed by Murphy (Peter Weller), Boddicker falls into the steel mill's water, blood spewing from his neck. Sharp eyes are required here to see that there is someone standing against the wall in the background... (01:32:40)
Dick Jones: I had to kill Bob Morton because he made a mistake. Now it's time to erase that mistake.
