Continuity mistake: When Ronnie takes Brandy out to dinner, when she asks him what his medication pills are, he holds them out for her to read, and as the shot changes from him to her, the position he's holding the pills changes from being held upright, to upside down. (00:30:25)
Continuity mistake: Ronnie and "Saddamn" are in the middle of the mall trading f-bombs: throughout the scene there are often inconsistencies regarding the position of various people walking by. It's especially noticeable when in some shots the corridors are crowded with people walking or slowly pushing strollers, but after a quick cut suddenly everyone has disappeared. (00:21:00)
Continuity mistake: Ronnie approaches Brandi (and incidentally, Bruce) with the excuse to talk about the perv. During the conversation, behind Brandi a woman dressed in black appears and disappears a few times, same as a woman with a white and green shirt who is leaving but comes back just a couple of shots later.
