Other mistake: In the hunt out in the wilderness - where Jane looks in the binoculars - there is a cover on one lens - but it shows you can see both sides. (00:30:27)
Continuity mistake: 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. (00:45:40)
Revealing mistake: When Pitt is on the roof of Jolie's car, he breaks the window in order to get into the car. First off, when played in slow motion, the feet never do touch the glass before it explodes. Second, all newer vehicles have shatter proof glass both on the windshield and the side windows. In real life the glass would have just cracked, not blown out as it did in the film. (00:46:25)
Continuity mistake: 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. (00:50:15 - 00:51:45)
Continuity mistake: During the scene when John and Jane are dancing in the hotel restaurant when they first start to dance the large set of windows are behind them but once they start to move just before he knocks her head into the mirror breaking it they now have the large window still in the shot but now on the left side of them even though they never turned except there is a cut. (01:03:22)
Continuity mistake: When John and Jane reach home after racing each other from the restaurant and she crashes her car into his, he's wearing a black jacket just before she hits him and no jacket just after. (01:05:15)
Other mistake: In the scene where Jane and John race home, we see Jane smashing her Mercedes C320 wagon into John's Lincoln town car. Both these vehicles have airbags, yet they do not deploy upon the impact between the two cars. (01:07:25)
Continuity mistake: When Brad and Angelina are in the basement right before it blows up, Brad is holding a 6 shooter and when he is running out of the basement the second he runs outside and starts shooting he is holding a different gun. (01:21:25 - 01:22:00)
Continuity mistake: During the beginning scenes of the car chase, the golf bag moves in the trunk. In the first clip there are some bags in front of it, but in the next it's all the way in the back of the trunk. (01:21:35)
Continuity mistake: During the car chase, the wound on John's cheek changes colour between shots. (01:21:55)
Continuity mistake: During the car chase you see several clips where the car's sides are bumped and have bullet holes, but also several clips where the cars sides are in pristine condition. (01:23:15)
Continuity mistake: When the Smiths steal the van from the Coleman's, a cross on a rope is hanging from the rear view mirror. During the BMW chase, the rope goes from being almost a foot long to about two inches long. (01:23:30 - 01:24:40)
Continuity mistake: When John sees the BMW's in the rear view mirror for the first time, the cross hanging from it disappears. (01:24:30)
Factual error: While John is crawling through the sewer pipes, Jane's monitor shows his GPS location as 47.28 N 12.46 W, 35 feet below sea level. This places him under the Atlantic Ocean, somewhat north of the tip of Spain - nowhere close to New York, or any other streets for that matter. (01:34:00)
Continuity mistake: The second time John and Jane enter the elevator, they both have machine guns. However, when they exit, Jane is holding a handheld pistol and they have swapped sides. (01:42:00)
Continuity mistake: In the store, John takes out two mercenaries with a pipe wrench. They had suppressed MP5s. When Jane and John take the weapons, the suppressors have gone. (01:44:17)
Continuity mistake: Near the end, when the Smiths are hiding in the shed, from the inside the front of the shed and the door have several bullet holes (as do the sides), but in the long shot of the shed, the front is in perfect condition. (01:45:00)
Factual error: The movie is supposed to take place in and around New York City, however during the car chase where Angelina and Brad are fighting off the three BMW's, a wide shot clearly shows a street sign announcing Los Angeles.
Continuity mistake: During one of the scenes when Brad Pitt arrives home, he is driving a Lincoln Town Car, not his Cadillac. This is the car that he doesn't get until later, when he steals it and drives home during the scene when they crash the cars into each other at the end of the driveway.
Suggested correction: Didn't he steal the Lincoln after the restaurant?
He did. But, the car appears before he steals it when he drives home after going to her office.
Visible crew/equipment: John pushes his newly captured prisoner into the back of the van Jane is in. As he closes the van door you can see an extra arm behind John's back moving over to hold the doors closed.
