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?
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.

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.

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.
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.
