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: 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 Monty drives Withnail & I into Penrith the radish is on his left lapel. When they arrive in Penrith a few minutes later, the radish has mysteriously moved to his right lapel.
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: 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!
Continuity mistake: At the beginning, before Karla's robbery of the jewelry store, when the limo turns the corner the front license plate reads "Dent". However, when the limo parks in front of Adriano's its front license plate reads "77". (00:00:25)
Continuity mistake: Danny Devito leaves the bar and he begins to smash the windows in the car. In some frames the windows are intact then broken then intact and so on.
Continuity mistake: In the scene in the empty office, as the camera angle changes, Fox's hair gets noticeably longer and darker.
Continuity mistake: When Ash is crawling through the cellar, he finds some of the pages, and he holds them in his right hand. Only problem is, he cut off his right hand earlier and attached the chainsaw to it - the film was flipped so he'd appear to be crawling in the right direction. (01:06:15)
Continuity mistake: In the scene where Emme is flying through the store, you can clearly see a rope guiding the path of the glider.
Continuity mistake: Near the middle of the film we see that Michael has a transparent reflection in a mirror because he is a half vampire. Yet, earlier in the film when the other vampires, who are full vampires, are in the video store, their reflections can be clearly seen in a glass counter. (00:12:10)
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 Hi, Gale and Evelle are sitting in the trailer talking about robbing the bank, watch the newspaper on Hi's lap. It goes from being folded to being fully opened in his hands between shots.
Continuity mistake: When the William Hurt character is talking to Holly Hunter after her boring lecture, the first shot (from behind Hurt) shows him walking backwards while talking to Hunter. As he continues to walk, he comes perilously close to banging his head on an archway. Yet, on the reverse angle, Hurt has been repositioned about five feet from where he was.
Continuity mistake: In the car chase scene, the escaped convict and police are exchanging gun fire between cars. In the different shots of the police car, the bullet holes in the windshield appear and disappear several times. Also, when three shots have been fired at the police car there are four bullet holes in the windshield.
Continuity mistake: When Daryl first meets Sukie, he has 4 scratch marks on his face, but when they play tennis, he only has 1, and then in the swimming pool, it's back to 4.

Continuity mistake: When Cronauer first goes with Tuan to see the Vietnamese village, he is wearing a white shirt. In a subsequent shot, the shirt is plaid.
