Revealing: 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: 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.

Continuity: 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.

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.

Deliberate "mistake": When Brad Pitt is in his garage and cleans the spot on this collar, he should have turned the car's mirror to the left to see himself. Instead, he turns the mirror to the right so the camera can get a view of his collar.

Continuity: 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.

Factual error: In the scene that depicts the Smiths meeting each other, they are supposed to be in Bogota, Colombia. The tropical village they're in looks very little like Bogota, a gigantic metropolis with over 9 million inhabitants and very cold weather.
