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: When the "ghost" is first seen, it is mostly obscured by a curtain; only its right shoulder is visible. In the next shot, however, it is right in the middle of the window, and nearly the entire cutout is exposed.
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: 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: 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)Quantom X
Continuity mistake: After Todd Howard knocks out his opponent in the boxing match, the crowd immediately starts throwing cups of popcorn into the ring. The camera cuts to Todd cheering and then an overview shot of his opponent laying face down on the canvas. At that view you can see that there is no rubbish or popcorn or anything else in the ring. Then when the camera cuts back to a side view there is loads of rubbish and popcorn all over the place once again.
