Other mistake: After the longest introduction ever, a text crawl (in English in the original version too) details the event leading to the titular fight club. It says that the city fell "A PART" and the institution "IS COLLAPSED." Also, it warns us; "cannibalistic zombies are malformed." (00:59:30)
Visible crew/equipment: When the little boy is lying in bed looking up at a hole in the wall you see a creepy hand move, the while time, if you look closely, there appears to be a human hand with human fingers to the right of it in the darkness.
Continuity mistake: Roy is on his back at one point, seemingly knocked out. A shot later he's suddenly on his stomach before regaining consciousness.
Continuity mistake: At the end when Sarchie is hugging his wife, in one shot the bandage on his arm has unravelled. In the next, it is neatly wrapped.
Continuity mistake: When the crocodile catches the man he bites his right foot off. 5 seconds later as he falls into the water his foot is back. (01:21:05)
Factual error: Newgate makes a reference to Mickey Finn's name being the same as that of a Chicago bartender who used to drug his patrons with knockout drops. However, the film is set in 1899, but the real Mickey Finn wasn't caught until 1903.
Continuity mistake: The students' 3rd game is Kagome with 4 Kokeshi dolls. The pink doll starts to the right of the first student to play, the dolls move in a circle around him, she passes in front of him and by the end of the shot she is near his left. The Kokeshi dolls all move backwards between shots and the pink doll passes in front of the student again. After this, she takes 7 seconds to move about 100° despite nobody slowing down and she took that amount of time to move about 170°.
Revealing mistake: As Glenn, Blake and Monica are being surrounded by zombies, as Monica asks "Fucking hell, how many more of these are there?", in the background you can see a zombie sitting astride his victim, flailing away with a hammer or hatchet. It is obvious that he is just swinging his arm back and forth, without connecting with anything. It looks as if he is dusting, not slaying someone. (01:23:50)
Continuity mistake: Carrie's height changes constantly.
Revealing mistake: When the woman is tied to the bed, she is holding the ropes, and the rope isn't tight on her right hand; she can easily escape. (00:20:10)
Factual error: The alien drops the video camera out of the UFO from outer space and it falls to earth landing on the ground. This very far drop would certainly have busted it to pieces, if not ignited it on reentry, but when the guy picks it up off the ground, it appears only the screen is cracked.
Continuity mistake: As the jeep with the killer goes over the cliff and smashes face down you can see nobody is in the jeep as it disintegrates the front part. (01:14:00)
