Continuity mistake: The business card given to Dan Zavitz by Bobby Dean in the lingerie shop is not the same business card removed from his pocket by the agent after he gets hit by the fire truck (second timecode). The email address along the bottom of the card has changed, In the first shot, it's 'email@example.com' and in the second it's 'firstname.lastname@example.org'. (00:25:00 - 00:26:45)
Continuity mistake: In the scene in the lingerie store Will Smith is talking to a blonde assistant. She has a piece of her hair tucked up behind her ear, but as the shot changes her hair is down loose again. When the shot changes again the piece of hair is behind her ear again. This happens roughly about 3-4 times.
Continuity mistake: In the scene where Robert Dean and Rachel Banks are having lunch in the diner, the mustard bottle is seen in two different places. It starts out to the left side of his plate, kind of behind the napkin dispenser. When she gives him the tape, it moves to the front of the dispenser. In the next shot it goes back behind.
Continuity mistake: When Dean is lying down in the back of the womens station-wagon, you can clearly see the driver's neck and hair. On a close-up of the driver, you can see that there is a head-rest in the way. On return to the wide shot, the headrest has obviously been removed.
Continuity mistake: When all of the politician's 'henchmen' are leaving 'the office' one of them is wearing sunglasses, that he did not previously have on in that scene.
Continuity mistake: In the beginning scene with Jason Robards and Jon Voight talking on the bench, there seems to be a difference in temperature between shots. When there is a close up of Jon Voight, you can see his breath in the cold air. When there is a close up of Jason Robards, no breath is visible at all.Steph_Jared
Continuity mistake: When Dean is on the 17th floor, running from the NSA guys in the hotel, Mr. Wu's room number is 1721. But the NSA guys radio they're at room 1712, and it ends up being the one Dean and the Wus are in.
Continuity mistake: While in the burning car, we see the fire engulf Robert Dean's arm, up to the shoulder, as well as in his lap. But during shots from outside the car, there's no sign of him being engulfed in flames. Then in the last shot, his jacket is back on fire, but not as much.
Continuity mistake: At the Reynolds' residence, when Tom walks into the bedroom, his wife's hand is on her chin. In the close up shot of her asking if anything is wrong, her hand is no longer there and her arm is down, then in the next shot, her hand is back on her chin.
Continuity mistake: When Will Smith first escapes the ambulance he runs down a tunnel. There is little or no traffic, but when when the agents are closing in on the truck with the power washer, it is jammed nose to tail. Where did all the traffic come from? It wasn't busy enough to create such a small bottle neck of a traffic jam.The_Iceman
