Continuity mistake: When Christy walks into Station 51's kitchen, the bag strap is on her shoulder, but close-up it is gone, only to be back next shot when she removes it a moment later.
Continuity mistake: The shaving foam on DeSoto's face changes between the face-on shots and the reflection shots, and in the reflection he shaved from cheek to chin, but in face-on shots only to the neck.
Continuity mistake: Gage and DeSoto arrive at the apartment complex, home to the guy trapped in the couch. They park the vehicle and walk on the gated balcony to the apartment. In the exterior shot, when they enter the doorway the inside wall to their left is bare and the corner of the balcony's iron gate is to the doorway's left. Next interior shot, now there is a large painting on that previously bare wall and the iron gate is directly in front of the door. When they leave, their vehicle is farther away, positioned differently.
