Continuity mistake: RoboCop storms out of the underground base taking with him his hand attachment, but when he arrives at the police station he has the hand attachment on. A few scenes later he arrives at McDaggetts hotel, and now does not have the hand attachment on, and is back to using his normal gun. Then, when he returns to the underground base, he still is using his normal hand and drops the hand attachment on the ground. So in between all these scenes, where was he keeping his hand and the attachment? He was on foot all the time, and he obviously wasn't carrying them both...
Continuity mistake: When Robocop is rebooting after being repaired, he is imaging going through a wormhole of sorts. He sees his wife there. Then, his wife morphs into Lewis. Then, it morphs into Lazarus. However, the mole near Jill Hennessy's mouth is on the wrong side in that shot.
Continuity mistake: Towards the end, while the Rehabs recruit gang members and the punks are struggling with the cops and deputized citizens, the sun changes in several shots.
Other mistake: After officer Lewis dies, the camera close-up shows her breathing. There is also eye movement.
Other mistake: The explosion at the gates to the Police Ordnance depot is utterly ridiculous. They blow up steel gates with dynamite, but the resulting explosion is a fuel type flame. It's metal they are blowing up, not a combustible material.
Continuity mistake: Watch the subtitles in the police chase against the battered yellow van. In one scene where the two gentlemen are narrowly escaping the hit, the young officer says "ease it up" but the subtitles say "jesus".
