Continuity mistake: When Bob and Robby are eating Mexican food, Robby borrows a bottle of hot sauce from a neighboring table. When he gets done putting the sauce on his food he places the bottle on the right side of the table. The bottle remains there until the end of the conversation. At the very end of the conversation we see that the bottle is now in the center of the table directly between them.
Other mistake: In the credits at the end of the film "Editing" is spelled "Edting."
Continuity mistake: When Tim goes to the house and Kate falls off her horse, they go inside. When she leaves you can hear a car engine start. If she rode her horse to the house how did she get her car there?
Continuity mistake: In the scene where the Griffins are having breakfast and Stewie is drunk, Brian has one egg on his plate, and some bacon. After Stewie jumps from the shelf, Brian has two eggs and no bacon.
Continuity mistake: In the scene where Simon is having dinner with Theresa's family, Theresa has a bowl of salad. She puts some salad on her plate and then some on Simon's plate. When the shot changes she is putting salad on her plate and Simon's plate again.
Continuity mistake: When Minty arrives at the North Pole in a balloon, she passes Santa's house twice.
Other mistake: When Owen first meets Dodger, and asks if its that obvious he's a transfer, she tells him "It's a small school, word travels fast." During a flashback to this scene at the end of the movie she says "word spreads fast," instead.
Continuity mistake: After Train transports everyone across the narrow bridge over the lava, he slouches down to the ground in relief. In the next shot he is standing straight, looking normal.
Other mistake: Michelle Rodriguez's accent changes several times, not only throughout the movie, but sometimes within the same scene.
Continuity mistake: When Valiant flies down the gun barrel, he takes off his backpack and helmet, and he lays them down in the barrel before squeezing through the back of the gun. When he comes back out through the gun with the other birds, the backpack and helmet are not there.
Factual error: Throughout the movie, the television sets at ABC are airing historically relevant news broadcasts. However, the events are always shown on the same day as key episodes of Dynasty, but completely divorced from the real date of their occurrence. For example, President George Bush is alleged to have been sworn in on the day the finale aired, May 10, 1989, when it really happened in January of that year.
Deliberate mistake: With John Cusack leaning to the side to pull Diane Lane and the dog from the water, the rowing scull should have nearly tipped over, yet it leans only slightly. Later in the same scene, the normal instability of such boats can be seen when tipping occurs to a greater degree simply from the dog moving.
Continuity mistake: Sean is standing by a window when Ray throws a chain through it and the chain wraps around Sean's neck. The following scene has Sean being pulled through the window, breaking away all the glass and the wooden dividers. When the scene cuts to the outside and the kids looking at Sean being pulled away, two broken wooden window sections have managed to regenerate and are visible from both the right and left sides of the window frame.
Factual error: Throughout the movie, as the train speeds through the starry night, the constellation Orion is recognizable (presumably rising) on the horizon. Oddly, Orion never rises any higher as the night progresses. Also, at the latitude of the southern U.S., the constellation would not rise (or set) vertically as shown but would be tipped at a considerable angle.
Other mistake: When the zombies come out of the river and start marching, look closely. The first zombies to come out wear wet clothes, but the ones in the back are dry.
Continuity mistake: When Mother and Mameha are waiting for the bid on Sayuri's mizuage, Mother's cigarette is short at one point, but becomes longer in the next shot.
Continuity mistake: When Terry is driving to see Denny, there is a shot from inside her car where the rear-view mirror is not attached. The next scene in which she is driving to Terry's, her rear-view mirror is mounted on the windshield.
Continuity mistake: In the scene where Nat and Iris make love for the first time she takes his shirt off of him. But in the next shot it is back on, and in the following shot it is off again.
Continuity mistake: The white Mercedes has a sunroof in some shots, and not in others.
Continuity mistake: In the bar scenes, the Dos Equis beer bottles change position pretty much after every shot. Sometimes there are three bottles in a row, then two, then three again. And when the bottle of nearly full beer gets tipped over, not only is there no spill, but no foam generated from the bottle being shaken the way it was.
