Other mistake: In the scene where they're loading Tom Cruise's first victim into the trunk, as Max lifts at the arms you can see the "dead" guy holding onto Max's forearms. (00:20:55)
Continuity mistake: Near the beginning of the film when we see Max pull up to the first hit location and Vincent is talking to him in the back; watch closely and in one shot we see that Vincent has his hands below (probably on his knees), but in the following shot we can see his left arm is now up and grabbing onto the glass that separates the driver from the passenger inside a taxi. (00:16:25)
Audio problem: Just as the two criminals who robbed Max are walking away, Vincent asks them if that is his briefcase. The guy with the long hair replies, "Yeah it is. Why you want it back?" but his mouth doesn't match what he is saying. It appears he is saying something closer to, "Put up your f**king hands." (00:35:15)
Factual error: When Max and Vincent are at the second contract killing destination, Dispatch calls and Vincent is holding the receiver. In one particular shot he does not release the button on the side of it and we hear Lenny speaking. This would not be possible: he would have to release the button first to hear what Lenny is saying. (00:29:55)
Continuity mistake: When Max and Annie are walking away from the train, in a shot from behind Max has his right hand on Annie's back, but in the following shot from the front Max's right arm is all the way around Annie fixing her jacket. (01:47:35)
Continuity mistake: When Vincent is shot in the face, the bullet left a long gash below his cheek across his jaw line. A couple of scenes later, when he's in the train the gash is gone. All we see is make up which is supposed to be blood.
Continuity mistake: When Vincent faces Annie for the first time in her office, her face and forehead are all sweaty and her hair is a mess and all over her face. In the following scene where Max and Annie are in the elevator, Annie's hair is back to normal and is very well combed. Also, her face is not sweaty anymore.
Visible crew/equipment: When Jamie Foxx enters the building where the girl works, he finds the dead guard - right after it he runs alongside a marble wall where you can see the cameraman running beside Foxx. (01:37:15)
Continuity mistake: In the scene when Max and Annie get off the train after Vincent dies, it is pitch black. After the train moves away, and Max and Annie walk down the street, dawn has broken.
Continuity mistake: When Vincent and Max pull up to the second hit location the windshield is no longer cracked. Best viewed when paused. (00:30:00)
Continuity mistake: When Foxx and Cruise are in the lift with the cop in the hospital, the door to the lift closes all the way to the right. When they get out, the door closes in such a way that two doors meet in the middle.
Continuity mistake: At the third contract killing, where Max and Vincent are sitting at a table in the jazz club with Daniel (the owner), watch the glass and receipt on the table, in one shot both the glass and receipt are on Daniel's side, then in the following shot both the glass and receipt have moved across the table somewhat to Vincent's side. (00:39:45)
Continuity mistake: In the club Fever scene, the detective (Fanning) sees Max and runs to him. In one shot, he has his gun in the air in his right hand. In the following shot, it has vanished. (01:20:25)
Continuity mistake: When Vincent is in Annie's office and looks over the desk, her cellphone is on a file which is also under the office telephone, but in the following shot her cellphone is now on the desk. (01:34:25)
Continuity mistake: When Max and Vincent are in Max's mother's hospital room, Max is at the window and in some shots the window lever is in the open position and sometimes in the closed position. (00:48:40)
Factual error: Toward the end, when Vincent et al board the train, they're on the southbound Metro blue line out of 7th Street station. The next stop should be the Pico station, next to Staples Center. But we see them get off an eastbound train along the green line, half an hour's ride and a transfer away.
Continuity mistake: As the feds and Max and Vincent arrive at the club, there is a shot from the feds car of the taxi pulling into the side street where the club is, the shot goes back to in front of the cab, and they are just turning in, even though in the previous shot they should already be in the street. (01:14:50)
Continuity mistake: In the club Fever, one of the Korean bodyguards gets up off the ground and runs to restrain Vincent. As he gets up, the people around him are dancing when they're supposed to be running around panicking. When Vincent shoots the bodyguard holding the MAC-10, another bodyguard in a white suit is visible in the background already trying to pull Peter Lim out of the booth. The bodyguard does not run to Peter Lim until a few seconds later in the scene.
Continuity mistake: When the feds are on the way to the club to protect their witness, the lead agent has his walkie talkie by the side of his head. When the shot goes to outside the cab, he's putting the walkie talkie to the side of his head again. (01:11:45)
Continuity mistake: When Vincent is talking to Daniel (the trumpet player), Daniel's upper lip changes from sweaty to dry at least 3 times.
