Continuity mistake: In the 1978 flashback scene, Michael does not have 6 bullet wounds in his chest from when Dr. Loomis shot him moments earlier.

Revealing mistake: When Tommy Ross gets killed and Carrie looks at his supposedly lifeless body if you look closely you will notice he blinks revealing that he is actually alive.

Visible crew/equipment: When Marcus attacks Simon at the loading dock, as Simon flies through the air after Marcus kicks him, you can see the face of Johnny Lee Miller's stunt double. (00:57:15)
Continuity mistake: Saw VII takes place straight after Saw VI. In Saw VI we see Jill put Hoffman in the bear trap and leave. We then see that Hoffman spends around 45 seconds trying to get the trap off before putting in the bars on the window. In this film however, just after Jill closes the door we see the glass break. No delay. (00:08:20)
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: Water can't put out chemical fires.
Suggested correction: Nonsense. Not all can be put out with water, some can.
If you did research on fires you will see that putting water on chemical fires makes it spread. Gasoline and oil float to the surface of the water and continue to burn.
Continuity mistake: The birth of the Predalien in this movie is completely different than it was in the first AVP. The lights on the table are different and the Predalien bursts out differently than in the first film. (00:01:30)
Revealing mistake: In the opening scene where the zombie kills Johnny. When they fall against the tombstone you can tell it is a dummy.
Continuity mistake: When the members of the brotherhood beat up Mani until he is dead, they pick him up above their heads. The tattoo on his torso appears to be on his right side, whereas in previous and following scenes the tattoo is on his left side. That shot is flipped.

Factual error: When they're first entering the whaling camp, a penguin startles Miller. That penguin was a black-footed penguin, which is a bird native to much warmer climates. If that little guy had actually been in Antarctica, he would have died within minutes. (00:20:40)
Continuity mistake: As Brian lands the plane down to Bangor, his headset is on in a frontal shot, but in a reverse shot it isn't. (00:47:05)
Factual error: Winter in Antarctica would not have a night and day as portrayed, with the amount of light changing so much during the course of 24 hours.
