Continuity mistake: When Salt and Winters first start talking between the glass window in the bunker Salt's body is facing slightly to the left. The camera cuts to the front of Salt and she is now facing right.
Continuity mistake: After Salt is arrested at the V.P.'s funeral, the police vehicles drive up a ramp directly behind the building with the Silvercup studios sign on the roof, yet when she is attempting to escape and rams the SUV she is in into the back of the escort patrol car in front of her, you can see they are now in front of the Silvercup studios building which is now a couple of blocks away in the background. (00:50:30 - 00:51:20)
Continuity mistake: The blood on Salt's face changes between shots, as the helicopter removes her from the White House lawn. (01:23:10)
Continuity mistake: Salt is in the Russian boat approaching the radioman. She throws some grenades down the stairs and some around, and explosions occur with fire and bits and pieces flying everywhere. Then she goes for a walk to kill some more guys and when she comes back to the same place it all looks nice and clean as before, no dust, no mess at all.
Continuity mistake: In the scene where Salt was escaping from her home and hid from her pursuer by dodging behind an air conditioner on the outside surface of the building, the previous scene shows that there's not enough space for hiding.
