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.
Visible crew/equipment: When Cain and his gang are making their escape from the drug factory at the start, we can see a crew members hand very obviously poking out from behind the door frame, giving the actors their prompts when to go.
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.
Revealing mistake: When the mayor is sliding down the sewage drain, you can see some kind of a mat or something under him, probably to make him slide better.
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.
Revealing mistake: When Robocop finds Hob shot and dying in the back of the truck there are close-ups of Hob lying on piles of the drug money. In one shot the $50 bill on the top of a stack of bills is lifted at the corner and you can see that the bill under it is blank paper.
Deliberate mistake: When Robocain tries to use his chaingun on Robocop and it isn't armed, he snatches the remote unit from the OCP psychiatrist. If you look carefully, the remote unit changes from real to animated as soon as he grabs it.
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.
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.
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.
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.
Continuity mistake: When Robocop lectures the kids about the hydrant, they are suddenly standing closer together between the first and second shot.
Visible crew/equipment: When Robocop talks to the baseball kids, the moving boom mic is reflected on his helmet.
Revealing mistake: After Robocop kills the man holding a baby, one can see the baby is a doll.
Revealing mistake: When the truck drives through the bar, the brick walls are a blatant thin piece of painted cardboard.
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.
