Visible crew/equipment: When Dr. Faxx is programming the new directives into RoboCop, the camera pans around RoboCop's body. You can see the reflections of a camera and a crew member on RoboCop's helmet. (00:47:55)
Continuity mistake: When RoboCop and Lewis go to deal with the baseball kids robbing the electrical store, they are shot at and Lewis spins the car round. We cut to a close up of the car and see Lewis get out, meanwhile RoboCop opens his door and puts his hand on top of the car, supposedly to get out. A few moments later he is still siting in the car, arms on his legs. So why did he put his hand up? (00:50:12)
Revealing mistake: Just before RoboCop gets out of the car to walk towards the baseball coach, Lewis shoots at the coach and he jumps back. Watch carefully. Whilst jumping, his hat comes off slightly and you can see the make-up for the hole in his head, which he doesn't receive for a few seconds after this. Seen best in Slow motion on the DVD. (00:50:31)
Continuity mistake: When RoboCop gets out of his car in the scene where the baseball coach is firing at him, the building behind him is reflecting the sun and looks very bright. Less than 2 seconds later we see RoboCop walking towards the electrical shop and the building is very dull looking. Where did the sun go? (00:50:36)
Continuity mistake: Watch the lights on the police car when RoboCop and Lewis are walking towards the baseball coach. They are on, but just after they start walking, they get turned off. After the baseball coach has been shot, they are on again. (00:50:43)
Visible crew/equipment: Watch very carefully when RoboCop shoots the man in the yellow shirt in the factory scene. The man falls down the stairs and just as he reaches the bottom, a pair of hands come out from the bottom of the screen to break his fall. (01:00:02)
Continuity mistake: RoboCop is being scraped up against a wall while hanging onto Cain's van. When he comes away from the wall there are no scrape marks on his back. (01:01:58)
Continuity mistake: When all the cops go into the nuke factory and one cop is hit in the leg, the other cop puts his hand over a bar and yells "give me your hand." As he pulls him, his hand is now under the bar, even though he never let go of the cop's hand. (01:02:00)
Continuity mistake: When RoboCop is being scraped up against the wall creating a shower of sparks, we cut to views of Cain. In one of these shots of Cain, the background suddenly changes - the wall he's scraping up against is nowhere to be seen and the sparks vanish. In the other shots of Cain, the background is correct. For some reason, a shot was taken from another part in the sequence and added in here, creating an odd continuity gaffe in the background. (01:02:02)
Suggested correction: This is not correct. When they show the interior shots, you can see the red brick wall out of the window.
This correction is untrue. You can find the scene on YouTube (look up the video "Robocop 2 (6/11) Movie Clip - Demolition Ride" and pay attention from about 0:55 - 0:58), and the background is definitely totally different - different type of brick, graffiti is missing, there's no sparks and it's in the distance. The original mistake is correct.
Continuity mistake: After RoboCop slams into the pole, watch the ground at his feet carefully, you can see that one of his calf pistons have broken off. Just a few moments later when he is on the motorbike, both calf pistons are intact. (01:02:21)
Continuity mistake: RoboCop overtakes Cain on his motorbike, and we see a shot from inside Cain's van. We can see that both of them are very close to the end of the street, and there are two small buildings on the right side of them. The width of those buildings are all the space that stands between them. RoboCop then builds up speed to about 60mph and charges towards Cain, passing several buildings on his right. There is no way RoboCop could have travelled that fast in that short a space, and there is no way he could have passed more than 2 buildings. (01:02:54)
Continuity mistake: When RoboCain kills the chubby man with a moustache, his jacket falls down in the back shots, but it's perfectly fit in the front angle. When he finally collapses, it's falling down again. (01:19:50)
Continuity mistake: When RoboCop 2 is shooting everyone he shoots a news reporter and camera man on top of a van. When we see them just before they get shot, the reporter is talking into his microphone, but his mouth isn't moving. (01:29:23)
Revealing mistake: When Lewis is shooting at RoboCop 2 she quickly runs as RoboCop 2 aims for her. He shoots at the car behind her, and if you look closely at the boot lid, you can see slight dents made by the crew so that they can make sparks come out of the boot when it is shot. (01:39:17)
Revealing mistake: Just before the reporter and cameraman are killed on top of the van, a woman is running away from the scene and is shot in the legs, and she falls to the ground. A man comes to pick her up and he gets shot in the back. If you look carefully, you can see the marks that the vest he is wearing make on his back, (which explodes under his clothes making it look like he was shot). (01:39:25)
Continuity mistake: A man fires a rocket at a police car driven by Robocop, but when the car overturns and it's shot at, one can see it's empty. A moment later, Robocop opens the door and appears out of nowhere.
Continuity mistake: Robocop shows up at the presentation of RoboCain, but he disappears in the wide shots, only to suddenly reappear when the shooting starts.
Continuity mistake: When RoboCain steals the remote control, there's a woman in black walking up the bleachers. A shot later, right when RoboCain clicks the button, the woman is suddenly way behind.
Other mistake: When Robocop jumps on top of RoboCain, there's a moment where RoboCain backs up, and you can see a burning car in the background. The background footage is in a weird, stuttering frame rate that's unintentional. (Likely the result of the shot needing to be re-timed by doubling or tripling frames for the stop-motion animation in the foreground.)
Suggested correction: You need to be clearer. Throughout the scene, all the fire effects appear to be shot live action. What exactly is the mistake you're seeing?
The mistake is poorly worded, but correct. When Robocop jumps on top of RoboCain, there's a moment where RoboCain backs up, and you can see a burning car in the background. The background footage is in a weird, stuttering frame rate that's unintentional. (Likely the result of the shot needing to be re-timed by doubling or tripling frames for the stop-motion animation in the foreground.) I'll submit a word change.
Continuity mistake: When RoboCain smashes Robocop against the wall, the shape and size of the hole, plus the cracks around, change 4 times during the fight, depending on the shot.
