Factual error: In the climax of the movie, Nicholas Cage uses a nail gun like a marksman, hitting with precision the bad guy that holds his wife tight. Besides this skill of his coming out of left field, a nail gun does needs a surface against the opening. It does not shoot nails in the air without pressure being applied, it's a Hollywood trope. (01:18:45)
Continuity mistake: Jonah passes the phone to Avery, so she can stop the security from coming. She grabs the phone with her left in the first shot, then in the background we see her with the phone in her right hand. (00:58:35)
Continuity mistake: After kicking the heck out of Kyle, Ty grabs him and drags him against a wall. Kyle is suddenly holding his arm, and Ty has both hands clasped together but without underhooks on Kyle like he had before. (00:56:10)
Continuity mistake: When Elias says that "the younger the kidney the better" and Kyle understandably reacts to the phony story with an insult, the grip on his daughter's shoulder changes. (00:37:30)
Continuity mistake: In Jonah Collins' flashback after he punches the locker, Nicole Kidman's hair moves from behind to the front of her shoulder when he asks her if she designed the place herself. (00:30:20)
Continuity mistake: When Kyle tells the silly robber boss "In your hands, they go back to being nothing but rocks", Ben Mendelson is scratching his head, which he was not in the previous shot. (00:21:50)
Continuity mistake: When Elias drags Sarah in front of Kyle telling him to open the safe, the gun changes position against Nicole Kidman's head multiple times. Even accounting some deliberate discontinuities/skips in the action, in normal shot/reverse shot switching you can see her hair being over the gun and suddenly disappearing at the cut. (00:24:30)
Continuity mistake: A bad guy is about to give Kyle's wife more than a patdown to look for her cell phone, and Kyle goes nuts. He is easily overpowered, though. During this sequence, the hands of the home invader keep changing position on the prone Nicholas Cage. (00:14:20)
Continuity mistake: Avery's friend tells her about her mom bedding the divorce lawyer. Next shot, and Avery does her big girl reply with her hand on her forehead, which she did not have earlier. (00:08:20)
Continuity mistake: In the very last shot of the movie before the credits roll, Nicole Kidman's hair changes position on the forehead from the previous. (01:24:50)
Factual error: Avery crashes the car on purpose at top speed against a street lamp and undoes at the last moment Petal's safety belt. Neither airbag is deployed on impact. (01:16:10)
Continuity mistake: When Avery moves from her mom to his dad to hug him after being captured, Nick Cage's hair is suddenly more neatly arranged than earlier, and switches again between neat and messy on the right a couple times. (00:36:20)
Continuity mistake: At the beginning of the "You deserve to die" scene between Ben Mendelsohn and Nicole Kidman in the kitchen, the cork on the counter (its bottom) is facing left. She then faces the knife racks, and the cork is facing right. Goes back as it was when the camera angle is the same as before. Same for her left bang; gone, long to the breasts, gone. (00:32:40)
Continuity mistake: Elias makes it so that Kyle can't touch his glasses, and drags his wife away. Nicole Kidman is facing the door, but in the next shot (Kyle is shoved to the ground) she is facing him. (00:31:45)
Continuity mistake: Kyle is reaching for his glasses on the floor with a sweat-stained shirt in the first shot. The glasses change position on the floor (look at the lines between the tiles) and the sleeve dried up. (00:31:40)
Revealing mistake: The gang is starting to argue as they are running behind schedule. The big guy is holding Nicole Kidman at knife-point. The camera zooms in on her breathing heavily...so heavily that the 'metal' blade of the knife bends up and down. (00:29:00)
Continuity mistake: The younger brother threatens the big guy saying "If you touch her I will f**king kill you." The guy's knife is against the right half of Nicole Kidman's neck, while it's past the mid point in the shots before and after. Her hair is also changing position, look at the big curl on the last shot. (00:28:50)
Continuity mistake: In the first flashback when Sarah recognizes the youngest guy in the gang, her hair is parted differently over her shoulder in close-ups. (00:23:25)
Continuity mistake: In the reaction shot to the "Everybody wins and everybody lives" line when Kyle offers to cut the diamonds, Nicole Kidman lacks the long bangs that she is sporting in the rest of the scene. (00:22:30)
Continuity mistake: Avery is with the junkie rich guy who set up some coke on the table. The rolled-up note and the dollars by the border of the table change position at the cut. (00:16:50)
