Other mistake: During the flashback of the soldiers executing the Dachau guards, the soldiers are in a line opposite the guards who are in a line against a fence. The soldiers all start shooting at the same time, but we are shown the guards being mown down by gunfire in succession, like dominoes, rather than simultaneously.
Other mistake: When Salt was trying to escape in the CIA building, the tactical team was preparing to enter Salt's final hold up, the holographic sight on one of the tactical team member's M4 is mounted the wrong way.
Other mistake: In the scene where Jensen is attempting to decrypt the password on the hard drive with the algorithm, he uses the command "traceroute d-hea" which is commonly used to test network connectivity, not decrypt passwords.Then follows it with the command "dir" to reveal HTML code instead of directory structures.
Other mistake: When the man requesting money hangs up on him, a dial tone follows. Cell phones don't have dial tones.
Other mistake: Finbar is shown torturing a victim while the victim has his head in a halo used for immobilizing a person's head. The screws to hold the victim's head tight can be seen not to be touching his head, yet the victim is still bleeding from the screws.
Other mistake: We are seeing the movie as if we were watching recordings, that's why we see the surveillance camera shots as the device installed to change from one camera to another would let us. It takes very short time from one camera to another,but in some cases, as to follow things to happen, the shot stays in one angle (camera) for a longer period, not keeping the timing for the mentioned device.
Other mistake: Bobby extracts 2 teeth forcibly to get into the final room, however when he's in the other room his mouth is no longer bleeding. The blood wouldn't stop that quickly. (01:02:15 - 01:10:00)
