Continuity mistake: At the end of the movie when the mob guys come to the boat house to move the body, Barry the Blade shoots a raccoon with his gun which has a silencer. But, later when Reggie shoots the neighbor's alarm system with Barry's gun, it does not sound like it has a silencer anymore.
Continuity mistake: In the very first scene the cigarette's distance out of the box varies from shot to shot.
Factual error: When Mark and Reggie are fighting over whether or not to go to New Orleans, Mark starts walking toward the Memphis-Arkansas Bridge. There would be no need to cross that bridge as New Orleans is due south on Interstate 55. The Memphis-Arkansas Bridge is Interstate 40 and goes to Little Rock, AR or north to St. Louis.
Continuity mistake: When Mark is forced into Romey's car, the garden hose in the window keeps disappearing and reappearing depending on the shot.
Continuity mistake: Near the end of the film, in the diner, when Reggie Love is giving Reverend Roy the location of the senator's body. The camera switches back and forth between the two as they are talking. The ballcap Roy is wearing is backward, but in each scene, it is on a different place on his head. Low on forehead, high on forehead, and then back again. It's especially noticeable because of the amount of hair showing.
Continuity mistake: Near the end of the movie when Reggie and Mark are hugging for the last time, Reggie's hands change position between shots.
Continuity mistake: When Reggie is talking about the first four Led Zepplin albums, in the front shots her left hand is at her side, but in the reverse shots it's on her hip.
Plot hole: When Reggie is interviewing Mark in the hospital, she tells him that she will pick him up tomorrow about 2:30 for a 3:00 meeting with the FBI. But the next day, Mark comes running into Reggie's office after the attack from the hitman the night before, and she asks him what's wrong as if she hasn't seen him yet. The FBI shows up just seconds later.
Continuity mistake: In the waiting room when Mark is first confronted by the mobster, his hair shifts from parted one way in far-off shots, to the other way in a close-up shot.
Continuity mistake: In the early part of the movie, when Johnny Sulari is talking to Barry "The Blade" in his office, in the picture windows behind them a large barge can be seen carrying cargo that is passing by on the waterway in the background. As the scene cuts back and forth between the two men, the barge appears, disappears, then reappears continually.
Revealing mistake: Romy is seen reinserting the white handkerchief into the car tailpipe a couple times without burning his hands. The pipe gets hotter as the car is running, and the cloth stays white the whole time, even though it's in a dirty exhaust pipe.
