Continuity mistake: When Del comes out of the passenger side of the dairy truck, he is with a black eye, for no reason. The next scene, it is not there. It is there again when he admits to being homeless. (Steve Martin punched Del in a deleted scene.)
Continuity mistake: There is a scene where the Chipmunks and Chipettes are singing the song "Girls of Rock and Roll." In that scene, it shows the boys walking up the stairs together and from left to right the order is: Simon, Alvin & Theodore. The shot goes to the girls then back to the guys. The order of the guys has switched: (left to right) Theodore, Alvin & Simon.
Continuity mistake: Dick Jones brags (admits?) to Robocop, "I had to kill Bob Morton because he made a mistake. Now, it's time to erase that mistake" while Robocop is crouched on the ground, not only looking away from him from across the room, but also Robocop's eyes are in a vertical position. In the playback, Jones is facing the camera as though it were videotaped or filmed in a studio. (01:10:50 - 01:35:10)
Continuity mistake: When Eliot Ness is at Jim Malone's house for the first time, Malone's collar is opened, then buttoned, then open again.

Continuity mistake: After Montoya has hauled Wesley to the top of the cliff, he drops the rope on the ground, where it lands forming a couple of coils. You can see this as Wesley sits down and Montoya leans up against the wall. However, when they start their duel, the rope is hanging straight off the cliff, without any coils in it.
Continuity mistake: When Corrine takes off her blouse, she shows her children seventeen scars on her back that she got from being whipped by the grandmother.

Continuity mistake: The head of Mega-Maid mysteriously shrinks in size. After Spaceball-1 transforms into Mega-Maid, the head is gigantic enough for a Winnebago to fly through for a considerable length of time. However, later on in the film, after the head has been jettisoned and crashed on a beach, the head is only big enough to hold a few dozen people. This can be determined by the size of the people coming out of her nose.
Continuity mistake: In the scene after the prison break, we see Richards, Weiss and Laughlin walking through the city. On the big television screen there is a commercial for The Running Man game show. The footage they feature on the commercial is footage from the episode Richards is in. How could they show footage from that episode if it has not taken place yet?
Continuity mistake: The reporters in the movie are hiding and video tapping the "drug deal gone bad" at the beginning of the movie. For the location that they are taping, there isn't any movement, they stay in one place. However, when the kids are watching the tape both times, it seems to be like an actual tape of what was going on, not what they could have taped, because, not only do they have cuts (going from one actors face to the next with no transitions) but they also show a shot where you could see where the cameraman was hiding, little hard for him to hit that angle!
