Continuity mistake: When Frost has the head pure-blood vampire on the beach, after he pulls out his first vampire tooth you see blood all over his mouth, but when it shows the close up of him pulling out the other tooth, there is no blood. (01:04:22)
Continuity mistake: Mr. Furlong pushes Zeke into the fishing tank and it breaks, soaking him from head to toe with water. Moments later they are walking out and he is dry.
Factual error: At the end when Ben Willis and his son have Julie at the graves, Ray shows up with a gun. He fires at Ben but there is no bullet in the chamber. Later after the fight between Ray and Ben's son Julie picks up the six-shot gun and fires 8 shots at Ben.
Continuity mistake: When Mulder and Scully start frantically running from the bees inside the dome Scully is clearly seen untying her belt twice. (01:01:55)
Continuity mistake: When Jamie Lee Curtis is teaching a class, just prior to the class trip, a shot over her shoulder shows on the blackboard 'W.B. Yates'. It should be spelled 'Yeats'. In a shot a few seconds later the spelling has been corrected.
Plot hole: In the end of the film it is heard the police want to exhume the body of Charles Lee Ray from his grave site in New Jersey. Now when Chucky and the crew get to the grave site they find and kill a coroner who is digging up the body. He is the only one there at 1am, by himself, a lonely coroner without any police officers, after all this is a police investigation and I doubt the cops would have him there alone. Then right at the end the Detective who is hunting them arrives. Now he is a cop from Lockport, about six states away. A. Why did he drive all that way to see the body? B. A cop from all the way down there shows up but no new Jersey cops are at the scene?
Plot hole: During the end the murderer is thrown out the front window of the building. The students leave the building through the front door, but yet there is no body, and that doesn't seem to bother them!
Other mistake: When Daniel Baldwin carjacks the guy at the gas station (director Frank Darabont in a cameo) we can clearly see that his car is a Cadillac. However, in the end credits he is listed as "Man with Buick."
Continuity mistake: At the carnival, the glass of lemonade goes from half drunk to full. (00:32:20)
Other mistake: When the main characters are in the motel and they hear the moth flying outside the window, Stu, the creepy deputy with the glasses, picks up a shot gun and racks a round into the chamber. In the next shot of all of people firing at the moth through the window, Stu is now holding his revolver and fires with it. When he runs of out ammo with the revolver he picks up the shotgun again and before firing racks the pump again. Since he already did that the gun should have ejected the unfired shell that was already in the chamber from earlier, but no shell is ejected.
Continuity mistake: When Vivo finds Pantucci snooping around the cargo, he throws him to the middle of the mercenaries, and they all get around him, including T. Ray who smiles at him; when T. Ray smiles at Joey he is standing up, but when he gives the first kick he is sitting down.
Continuity mistake: In the picture of Morgan Moonscar in Simone's book, his scar is much longer than it was when we saw his ghost, and also later when we see his Zombie.
Revealing mistake: Near the end (DVD), when Sadako comes out of the TV, you can see where her finger extensions have been placed (you can see the join between her real finger and the fake one). (01:22:50)
Factual error: During the Mars-flight, the way the spacecraft uses the rocket thrusters is unrealistic. For example when they are nearing Mars, they should be using the rockets against their movement, to slow down the speed. But in the movie they are using the rockets towards Mars.
Revealing mistake: At the beginning, the dead policeman can be seen rolling himself with his arms. (00:06:45)
Continuity mistake: When Mike and Jodi are walking through the "deserted" town, supposedly everyone in town has been killed by The Tall Man, when the Tall Man walks down the middle of the street you can see an old lady pushing an empty shopping cart, and a car driving around a corner in the distance.
Continuity mistake: During the scenes where Detective Mike Gage is trying to track down Captain Howdy in his car via laptop and cell phone modem, he keeps looking at a certain driveway with a dog in it. Each time they cut back to the driveway, the dog is in a different place. The newspaper is also picked up and taken away by a man, and returns several times, each time in different spatial relation to the dog.
Factual error: For a nurse, Reed Buccholz seems to have very little knowledge of medicine.
Visible crew/equipment: When Marion is dead, you can see the camera panning back reflected in her eyes.
Continuity mistake: First, we see Mr. Renaldi put both arms above his head while lying on the bed. Then in the next shot, he has them both down. His arm changes continue for the next two shots. (00:34:10)
