Continuity mistake: At the start of the movie when the gun store is being robbed, one of them fires a portable rocket launcher at the police car, causing it to roll over and spin. As it comes to a stop just outside the store, it's visible that the driver's side window has been blown out, and the vehicle interior is visible, however when the same guy prepares to fire the bazooka to finish it off, the window has returned and is completely intact.
Continuity mistake: When the mayor turns up at the steelworks to speak to the boy about getting money, the limo has square headlights and white-walled tires. Cut to a few scenes later when Robocop 2 has already turned the limo over, the headlights are now circular and the tires are all black.
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)
Continuity mistake: When RoboCop is in the street with his new directives, he shouts "Back" at Lewis and puts his hand down to take his gun out. We can see his hand going down beside his leg and then coming up with a gun, but his hand was nowhere near his leg, and even though we hear the leg opening sound effect, the leg never moves. The same sort of mistake happens after RoboCop 2 destroys the Nuke hideout. RoboCop is investigating, and afterwards puts his gun away. The gun goes down to his leg, but the leg never opens, yet the sound effect is played. Sloppy camera work is responsible for both cases, it should have been higher up.
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: When Caine's cronies throw the dismantled RoboCop out of the limo in front of the police station, take a look at the shot of the pile of parts. Both of his forearms are intact from the hand right up to the elbow. However, his right hand was blown off at the wrist just before he was "stripped".
Continuity mistake: When RoboCop and RoboCop 2 burst out of the window at the top of the OCP Tower, you can hear someone say the word 'sh*t' as the two hang onto the ledge of the building. No-one else is up there.
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: 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)
Continuity mistake: When Robocop's car gets hit by the rocket at the start, it spins to a halt with all the doors closed. When we cut to the guy with the launcher, the car's in the background but the driver's door is now open.
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)
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 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: 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.
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: After Robocop is knocked to the ground, three motorcycles approach him. The last motorcycle, as it approaches, has its headlight off. However, when Robocop grabs the bike to stop it, the headlight is on.
Continuity mistake: After turning off the hydrant, Robocop is talking to the kids. As he does, a girl puts graffiti on his back, and sprays paint on his head. After they run off, you see very little color from the paint, then a moment later, the orange paint is totally visible.
Continuity mistake: At the nuke lab bust scene, Robocop knocks on a door that appears to open inwards. However, when the guy approaches the door inside, it's a door that swings outwards.
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.
