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)
Factual error: During the scene where it shows people all over the world, just before the shuttles take off, it is daylight everywhere. It would actually be dark or near dark in parts of the world.
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: When Gregor shoots the guy in the car after nearly killing the little girl, blood sprays over the window, but there's no bullet hole. If the bullet exited his head, hence spraying blood, it should have gone through the window too. (00:55:00)
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)

Revealing mistake: After the sniper is shot he falls through the wall. Look at his silencer when he hits the ground - it bends where it attaches to the muzzle. A real metal silencer wouldn't do that. (00:41:25)
Plot hole: The first time they communicate with the "entity" in the spaceship, they find a correspondence between numbers sent by the entity and letters of the alphabet. The entity presents itself as "Jerry". Later on, the entity tells Dustin Hoffman, "Stop calling me Jerry" - and then Dustin Hoffman realizes that the number-letter correspondence was wrong, and the actual name of the entity was "Harry". But if that is true, how could they have communicated without problems before? The very first word that the entity used was "hello", which would have to be displayed wrong, since it begins with an "h" and has an "e".
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: Toward the end when Crews runs in with Red he first knocks his right headlight out, later it is back in, then it's out again (01:21:40)

Continuity mistake: When the young Chinese girl is kidnapped, while in the car, her tie is on. When she tries to fight the guy her tie is off in one shot, then back on again a few seconds later. (00:10:40)
Other mistake: When Will Smith checks into the hotel and his credit cards are invalid, we see that the time is 5:38 and it is daylight outside. The only problem with this is that it is supposed to be around December given all the Christmas decorations. It would be dark then in the Baltimore, not soaked with daylight.
Other mistake: When Ray shoots Kelly twice in the chest, and then himself once in the arm, all three shots are heard within a few seconds. However, in the flashback at the end, Ray shoots himself about ten seconds after.
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?
Continuity mistake: When they are driving away in the white car they go on their side and drive around and then get flipped back up and there is no damage to the car whatsoever.
Continuity mistake: When the Mayor of New York is talking to the crowds and people can feel the ground bouncing, Godzilla is a fair bit away, but when she is stomping through the streets the people don't feel it at all - shouldn't they be thrown into the air from that proximity? (00:26:25)
Continuity mistake: During the bedroom scene, Annett Benning is stroking her lover's chin. Depending on the camera angle (pointing at her or pointing at him) her hands switch from left to right and back to the left. (00:43:25)
