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)
Revealing mistake: Tortured by the demonic voices in his head, Michael King goes into a self-mutilating frenzy with a kitchen knife, except that he squeezes the handle of the bleeding-knife prop a bit too hard and it squirts fake blood horizontally across his chest.
Continuity mistake: At the end of the film we see stuff being crossed out in a notebook. The lines that are drawn through the words keep changing from being perfectly straight to being at an angle.
Continuity mistake: There is a scene where she accidentally stabs someone - she gets blood all over her from the stabbing and then in the very next scene is wearing the same shirt without blood stains.
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.
Other mistake: When The Phantom's shot in the leg he somehow gets blood on his sack mask.
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)
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.
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°.
Continuity mistake: Carrie's height changes constantly.
