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)Padzter
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)Padzter
Continuity mistake: When RoboCop is at the Nuke hideout, he looks around the various artifacts that the gang have stolen. One of them is the skeleton of Elvis in a glass coffin. When we see the coffin from RoboCop's POV, (he is standing to the right of the coffin), there is a picture of the real Elvis to the left of Elvis's skull. When we cut to a wide shot of the room, RoboCop is still standing to the right of the coffin, but the picture beside Elvis's head has moved to the right hand side of Elvis's skull. A guitar which is sitting beside the coffin is pointing inwards during the Robo POV shots, but in the wide shots, is pointing outwards.Padzter
Revealing mistake: During several of the scenes, when people are shot; some of the impacts are accompanied by blood splatter, others just look like squibs that weren't filled with blood.
Visible crew/equipment: At the start of the film, RoboCop is in his police car, and it gets hit with a rocket and it flips over, and then slides to a stop. It is quite obvious that RoboCop is not in the front of the car, and that a silver plate has been placed in the driver's seat to make it look like he is.Padzter
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)Padzter
Revealing mistake: When the baseball coach is exchanging fire with Lewis, he reacts to a close impact. As he does, his arms brush his cap, and the makeup for the bullet wound on the upper left side of his forehead is revealed. When the fatal shot is fired, his cap is down in position again.Movie Nut
Revealing mistake: When Robocop punches through the door at the nuke lab it appears that one thickness of the door was removed ahead of time. When the guy looks through the sliding peep-hole it's obvious that the door is thick. But especially after Robocop removes his arm you can see it is only single thickness and you only see the shiny inner of the door peeled inwards and none of the brown paint from the outside.
Continuity mistake: Cain's extraction in the glass tube had green eyes. Earlier he appeared to have brown eyes.
Continuity mistake: During Cain's escape attempt RoboCop seizes someone's motorcycle. The motorcycle's lights vary between being on or off throughout the scene.
