Other mistake: While Fin and the others are on the subway, it keeps cutting to show about 15 people waiting on the platform at Grand Central, and nearly every one of those extras are also seen as passengers aboard the 7 with Fin, in different subway cars.
Other mistake: When Jordan drops Rusty's truck into the compactor, the excavator and its claw seem just too small for the job. You can see the truck has been sawed shorter as the truck's rear axles stay on the ground while the cab goes in the compactor. There is no possible way for the truck to snap in half like that when lifted. This small excavator would just simply have flipped over trying to raise the truck by the engine compartment.
Other mistake: While exploring the attic, Lane sees a yellow chair in the attic. Trouble is the attic opening is much too small for that size of chair to have gotten through.
Other mistake: At the beginning of the movie, a woman runs to the store to get help. She uses the pay phone booth outside. The UFO takes her and the whole booth. A minute later, the booth crashes back to Earth. The next morning, the sheriff finds her wallet in the debris. She wasn't carrying it and didn't have a purse or pockets.
Other mistake: During the dinner scene we see Finn pour Newgate a drink. Newgate then goes to drink from it when Eliza kicks him so he spills it. However due to the width of the table this should be impossible.
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)
Other mistake: When The Phantom's shot in the leg he somehow gets blood on his sack mask.
