Continuity mistake: When Fin stops near the school bus, the bus number changes from "278146" to "278245" during the rescue of the kids.
Continuity mistake: Just before the garbage truck mows down the policeman and continues through traffic, we see behind the cop a street full of stopped cars, and a building less than 100 yards away (the street starts at a T-intersection). There is no truck, and no way for it to have gotten onto the street at the speed it's going. (00:07:05)
Continuity mistake: They trick one witch with a record recording of a boy that is lost. H&G are thrown down by it and the witch picks up a branch and begins zooming off like it is a broom. Hansel is behind her, yet despite the witch traveling faster than he is running, somehow he suddenly gets in front of her and smacks her with his gun. (00:31:10)
Continuity mistake: When looking at the dog from the bedroom window, there are 2 windows in the room facing the dog. When we see the window from outside only 1 window is lit up, despite both being in the same room. (00:11:30)
Continuity mistake: When Eric locks Mia in the basement after she vomits all over Olivia's face, the amount of vomit on Olivia's forehead drastically changes between shots.
Continuity mistake: Barb's eyes are green throughout the movie, but when Chucky stabs her in the eye, the eyeball that rolls down the steps is blue.
Continuity mistake: John is taken down by a trap set by Hansel and puts a big hole in his back. He gets back up and is shot down by the Sheriff. As he is getting up a second time, it shows his back. There is no hole in his back or shirt before the Sheriff finishes him off. It also shows no hole or blood on his back in one shot when he is chasing with the bear trap before he is shot the first time. (01:16:45)
Continuity mistake: When Tommy collapses on the stage he is facing Carrie, but when Carrie tries to cradle Tommy, he is facing the backdrop.
Continuity mistake: In the scene where Heather runs through the fairground she grabs onto the back of the Ferris wheel seat and is taken up in the air. Leatherface throws the chainsaw at the cop and the next shot shows Heather coming back down the other side of the Ferris wheel. But she should be on the inside of the carriages as it just spins round on an axis. These kinds of wheels don't "twist" at the top otherwise the rider would just be staring at the inside of the wheel the whole time.
Continuity mistake: We discover that because time is non-linear in the Further, it was Josh's spirit who was the one knocking on the door in the original film. However, the knocks we see Josh make in this film don't quite match up with the original film. In this film, he knocks many times frantically, whereas in the first film, we only hear a few faint knocks in rounds of three. (The film tries to mask this by inter-cutting footage from the first film to illustrate the point, but it still doesn't quite match up).
Continuity mistake: After Mary slams Grace's face into the table, the blood on her face keeps changing size and shape.
Continuity mistake: When the group of girls first pulls up to the gas station and talk with Barney, the shadow cast by the sign is much longer than moments later when they leave. (00:11:15 - 00:12:50)
Continuity mistake: When Carlos is confronting Manny about the Black Forest, the light on Carlos' face keeps changing. The front views show the right side of his face in shadow. But the views from behind and side show the right side of his face is in the light. (00:34:50)
Continuity mistake: Before Iggy gets his horns, he got a shot of whisky in the bar from the blonde girl. The level of whisky changes between shots.
Continuity mistake: "Mama" takes and breaks Victoria's glasses when she tells her to stop attacking Annabelle. Mama then takes the two girls, and we next see them at the cliff edge...Victoria now has her glasses back on.
Suggested correction: When Victoria is back on the cliff with "Mama" she is not wearing her glasses at all.
Continuity mistake: Notice how Julie pumps her shotgun twice within a few seconds in the lab without once firing.
Continuity mistake: Charlie has set up a "security system" on the right side of the bed. When a double slaps Lindsay's hand, she goes over to a chair on the right side of the bed and the security system has vanished completely. It reappears when she returns to bed.
Continuity mistake: Radha Mitchell is giving a press release at the beginning of the movie. There are many microphones in front of her in rows. In the front row, from her left, are orange, black and blue microphones. In one shot from the front, another black microphone appears next to the blue one. (00:03:35)
Continuity mistake: Our group of jewelry thieves are on their way to "Zugarramurdi" in a stolen taxicab. The "green soldier" Antonio began to wash the color from his face. Nevertheless you can see, depending on the camera angle, that the green color is sometimes seen on his nasal bone and sometimes not. (00:20:55 - 00:21:30)
Continuity mistake: It is mentioned in dialog that during the last bird attack (the first film), a red rain was visible that seemed to drive the birds mad. However, at no time during the original film is there any red rain visible.
