Continuity mistake: The way Franck's scarf was wrapped and tied around his neck changed from when he was sitting on the steps (wrapped around a few times with ends folded under) to when he was standing along the guard rail (a loop down the middle of his chest). (00:15:09)
Continuity mistake: Ed Harris plays a property manager character and is featured in the beginning of the movie, walking with a pronounced limp, a seemingly painful gait. His character is shown in many other nominal scenes throughout the movie without limping. Most notable, shortly before the end of the movie, his character is shown dancing wildly, spastically, and jumping to music, seemingly unencumbered and fluidly, in a way that his character in the first part of the movie would not have been capable of doing.
Continuity mistake: Audrey is driving straight along the kerb before coming to a stop in front of her house. When Molly is getting out of the backseat, the Jeep and another vehicle are directly behind Audrey's rear bumper, which blocks her approach. (00:59:45 - 01:00:06)
Continuity mistake: Toward the end of the film, Hannah, who has had her face pummelled by one of the villains emerges from the creek having escaped the fire with only minor bruising on her face and a cut on the bridge of her nose. Immediately after that, they are rescued but her face is now deeply cut, both eyes are blackened and there is a deep gash on her cheek.
Continuity mistake: Samantha placed the bottle of glue on top of the metal object she glued, but the bottle of glue was on the desk and the metal object was gone when the doorbell rang. (00:04:56)
Continuity mistake: When Mother is shot and the cop is switching the guns, the bag of money is next to Mother's body. But when they show the body as the cop is driving away, the bag of money is gone.
Continuity mistake: After Diane lit and switched her cigarette to her right hand (and off-camera), most front views of her left arm showed it in front of her, along her stomach, but rear views showed her holding the cigarette in her left hand with her arm more perpendicular to her stomach. Whether her left elbow was fully on the table or over the edge also varied numerous times. (00:08:00)
