Continuity mistake: Aaron and Steven are talking in front of 3 human statues. When they begin they are on the left side of the front statue and when they change the angle of the camera they are on the other side of that statue. (01:10:50)
Continuity mistake: When Spencer escapes from Hathaway, he is barefoot. But after Hathaway shoots at him (and kills a guard in the process), we can see Spencer is wearing a pair of beige socks. A few seconds later, as Spencer runs down a flight of stairs, he is barefoot again. (00:23:40)
Continuity mistake: When El Blanco is outside Burt's home, and leaves, there isn't any hole in the ground after him. Later, in the movie, when El Blanco gets underneath the earth, he leaves a big hole after him. Why wasn't it like that the first time?
Continuity mistake: In Session 24, Faye gets into her aircraft and Ed all of a sudden looks down at Faye, from on top of the roof, and starts talking to her. Look at the back of Ed's shirt, it falls up and goes past her neck and rests at her head, when the camera cuts to a front view, the shirt is above the shoulder line. (00:14:20)
Other mistake: When Spike is strolling through the city, at some point he walks by one of those posts pointing to various directions. One of the signs is written in cyrillic characters and, below, we can read the "English" translation: Ruccian Town.
