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: 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: After Mac has stabbed the scorpion that was on Dillon's back, he puts on a box and crushes it with his boot. You see a clear picture before he crushes it and then after he lifts his boot away. It is facing a completely different direction than before he stands on it. (00:32:25)
Continuity mistake: In the beginning, after Dennis Quaid has been beaten up, the pins on his jacket are pinned, then hanging askew, then pinned again. (00:03:55)
Continuity mistake: When Sam goes into "The Sinker" bar, he goes over and talks to Stacy at the table. When he slips Stacy a photo of the Cherry 2000, between a wideshot and closeup the glasses on the table around Stacy change, as he looks at the photo. (00:22:05)
Continuity mistake: Nuclear Man dents the floor with his footsteps, but in a wider angle the floor is intact.
Continuity mistake: When the two cops pull the stripper over, their car stops in the middle of the road. When Beck and Gallagher pass them later, however, their car is closer to the pavement. Their car moves yet again when Beck looks back at them out of his window. Also notice that three headlights are now on, including one that the stripper blew out. (00:51:30)
Continuity mistake: The way that Derek's scarf is tied, and the position of it, and the way it hangs etc., changes between various shots throughout the movie. One good example is when he pulls the gun out of the stupid alien's body. (00:18:55)
Continuity mistake: During the sketch where the old man is zapped into the TV, when his wife changes the channel Ronald Reagan is stepping out of a plane that is light blue, but when the old man steps out of the plane it is now a dark blue with a silver strip.
Continuity mistake: When the microwave explodes, the bucket of chicken disappears right after the explosion. (00:48:50)
Continuity mistake: In the scene on the roof when the local hoodlum is attempting to take on the flying saucers you see the scene from two points of view. There are four people watching the local hoodlum getting fried. From the front, from left to right you see an old guy; a tall black guy; a women in pink and then a young guy with lots of hair. When seeing the scene from behind these watchers, you only see the old guy and the guy with the all the hair. Each time the angle changes the tall black guy and the women in pink are there.
Continuity mistake: A display rack which Sam knocks to the floor keeps changing position. (00:17:45)
Continuity mistake: When Walter is being rescued from the room he was trapped in, through the hole in the wall, we see the outside of the hole and Walter's body is outside except for his legs, and we see the hands trying to pull him back. In the next shot inside the room, Walter is again inside except for his head and arms. It repeats several times. (01:28:30)
Suggested correction: This is incorrect. Walter and Lisa are wearing similar clothes, making it look like he is in both rooms at once. Instead, as he is almost completely in the other room, Lisa is close behind him.
Continuity mistake: When Valerie Vomit is about to steal the Pepsi truck, we see the driver standing behind the truck. In the next closeup we see a cord attached to his pants and the truck, which, as a result, rips his pants off as Valerie speeds off with the truck. Yet in the shot previous to this, there was no cord attached to his pants or the truck. (00:29:20)
Continuity mistake: When the chimp, Goofy, is flying using the simulator, he's flying haphazardly and crashes into a red truck. He then turns and smiles at the trainer. In the next shot, he is flying haphazardly again.
Continuity mistake: In the opening battle sequence, Cobra Commander takes a bomb and sets it for 3:00 minutes. As he flies with his jet pack to the Statue of Liberty, it counts down to 2:58. He lands and places the bomb, and laser blasts hit all around him before he turns and flies off. This takes about 5 seconds to do, but the timer on the bomb stays at 2:58 for the full time of him landing, placing the bomb, and flying away. (00:01:35)
Continuity mistake: When George's wife asks him what made him drive all the way out here, their car is on the back of a large dinosaur at that moment. When it cuts to a closer angle for his reply, suddenly they are on a dirt road.
