Revealing mistake: When RoboCop is covered in flames at the start he walks through a window. Watch carefully, it actually shatters before he walks into it. (00:21:21)
Continuity mistake: Anyone else ever notice that in all three of the films, the name of the station that RoboCop works out of is always different? I'm sure these aren't in order, but, it's been called Metro West, Metro South, and Metro North. Sure, they may circulate him through the city, but, all the same cops always seem to follow him. Detroit needs to find somewhere to put excess cash if they have that much to blow on relocation for an entire precinct.
Other mistake: The first fight of Robocop against Otomo ends when he blows his head off. Nothing dangerous happens. At the end of the film two Otomos lose their heads, and they self destruct.
Visible crew/equipment: Watch the scene where Robocop is being assessed for fire damage in the lab. You can see a monitor on his far right side fluttering, however no other monitors flutter as the camera passes in the room.
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: During the Ninja robots' fight, the man behind remains in the same position all the time, except for the moment the explosion occurs, where he is briefly seen standing in a skewed position. An instant cut later, he's back in the previous position.
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.
Visible crew/equipment: When Robocop's hand is cut, lighting screens are reflected on his helmet and armour.
Continuity mistake: RoboCop bends down to pick up the map at his feet, and he does so by scooping his hand underneath it and lifting it with his thumb and index finger, as it is lying flat on the ground. Yet when the camera angle changes to show RoboCop correcting his posture, the map is now rolled up and he is holding it in his hand, which is now in a fist position. (01:20:22)
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".
