Deliberate "mistake": One of the times that Angelina Jolie uses her binoculars to watch the approaching convoy of humvees in the desert, she increases the magnification. At the same time, the view changes from showing the vehicles head-on to showing them more from the side.

Continuity: When Pitt is chasing after Jolie, he crashes through a fence and fires his gun, hitting the car's windshield. To the left of where Pitt is, you'll notice that there's one rail missing in the middle. When he climbs through the fence to the street, the fence rail has returned, and the hole left by Pitt is now slightly wider, just enough for him to climb through.

Continuity: After Mr & Mrs Smith have been fighting at home the neighbours knock to see what all the noise is about. Brad Pitt has his arm around Angelina Jolie and is holding a tie. In the shot before the discussion ends they have magically switched places.

Continuity: When Jane enters her house with the girls, the front door has a chain door lock. When John enters with the neighbor there is no chain door lock.

Factual error: At 1:24:48 (the BMW's chasing the van), the lead BMW has a California front license plate (white with red script) but in the rear shots taken from behind the Beemers, the BMW's all have white and blue New York rear plates. Also the front plate is gone after the initial shot.

Continuity: When they are both fighting each other in their house Brad throws Angelina against a wall and you can see that she is a stunt double. Submitted by Disney-Freak

Continuity: In the scene where Jane and John are driving the stolen minivan and fighting the BMW's on the bridge, the sliding side door and hatch alternate between shots of being opened and closed. Jane's hair flies around from the door being open, before it is ever opened for the first time. These changes occur between wide and close-up shots, and between Jane's and John's close-ups, throughout the entire scene.

Factual error: During the highway chase scene, the cars crash through the barriers on the highway, but they are filled with water. In areas like New York these are filled with sand, because the water would freeze in the winter. Submitted by pross79

Revealing: In the scene where Jane is trying to run over John with her car, she jumps from the driver's seat while John is in the back of the car. Right before the car crashes through the fence, you see John through the back window. You also see a head in the driver's seat, even though no one is supposed to be driving the car.

Revealing: When the Company attacks John and Jane in their house, laser beams are seen coming through the curtains. One of the beams moves sideways as if the gunman is looking around. But the beam only changes direction - it comes from the same spot in the curtain - which means that the gun must have been held right behind the curtain. Otherwise the spot on the curtain would have moved sideways. Submitted by Jacob La Cour

Continuity: In the scenes prior to the Smith's house being blown up, when Jane is wearing only a white shirt, she is not wearing a watch. In the scene just after their house is blown up, where they are lying in the yard, Jane is wearing a watch.

Continuity: Near the end of the movie when John and Jane are in the shed and taking off their suit coats, there is no slit or hole in John's right pant leg where, minutes before, it had been punctured by Jane's wayward knife.
