Continuity mistake: When they have just poisoned Charles Durning, Mark the painter falls to the floor pretending to be sick. During this scene the stopper in one of the bottles is out, then it's back in, then out and so on.
Factual error: Almost at the end of the film, Poncelet is marched to the death chamber, with Prejean's hand on his shoulder. They are led past an open door - which leads to the viewing room, where the witnesses will congregate. Some of them are already in the room. This is nonsense - it is inviting a bereaved relative to attack the condemned man. In fact the corridor to the death chamber goes nowhere near the witnesses' area, and Prejean would have had to have been escorted back through two guarded doors to reach it.
Continuity mistake: After Wallace gives the woman the balls of yarn, the balls change position between shots.
Continuity mistake: During the spectacular car chase David Caruso's car is speeding through the streets jumping 10'-15' feet in the air. On one of the landings in a wide shot, you can see that an air bag deploys, but in the next close up of him in the car, it's not there.
Continuity mistake: This is the car chase scene, where Ralph Fiennes and Angela Bassett are in a limo being chased by two bad cops in a pickup. Early in the scene, you have the view from inside the pickup when it rams the limo from the rear passenger side, and you can clearly see bullet holes in the glass and rear of the limo (no weapons fired yet). Then a few seconds later in the scene, you can see the rear of the limo with no damage. Moments later, you see one of the cops firing an automatic weapon, and subsequently witnessing the holes being made in the limo.
Continuity mistake: In one scene someone is smoking a DuMaurier Canadian cigarette which was taken from an American cigarette package.
Visible crew/equipment: When Christopher Walken throws Johnny Depp through the balcony, you can see the equipment which controls Depp's fall.
Continuity mistake: When Jimmy The Saint brings the cop to the "Man With The Plan" he starts yelling and one of the henchman raises his hand to Jimmy to stay calm and then he puts his hand down. The camera angle changes to a shot from the back and the henchman still has his hand up and Jimmy is saying his next line.
Continuity mistake: When the Colonel finishes talking to the General on the phone, he practically throws the phone into the army truck out of frustration. In the following shot, you can see the soldier in the truck with the phone in hand, as if it was calmly given to him, even as you hear the end of the "clunk" from when it was thrown. (00:52:50)
Revealing mistake: When Jim is rescued from the snow (thrown over Reggie's shoulder), he moves his leg, although he is supposed to be unconscious.
Continuity mistake: When "Telly" and "Casper" leaves Telly's apartment, his shirt is white. In the next shot when it shows them walking to the park, his shirt is gray. (00:35:25 - 00:36:45)
Suggested correction: He changes his shirt at his house. You must have missed it.
Continuity mistake: In the scene where the two police cars are chasing the truck, the two police cars crash into each other and explode - as soon as this happens the truck mysteriously disappears.
Factual error: The movie is set in 1948. When Easy first visits Albright about the job, Albright throws some $20 bills down in front of him. The top bill bears the signature of Treasury Secretary Nicholas F. Brady, which appeared on paper currency from 1988 to 1993.
Revealing mistake: When the tube is being inserted into Crazy K's nose, an imperfection in the tube is visible near the orderly's fingers. It doesn't move, despite the orderly "inserting" the tube.
Other mistake: In the exterior shot of the Grandeur Hotel, it's a poorly made building prop and its name is misspelled "GRANEDUR." (00:18:00)
Continuity mistake: The Black Scorpion's boots constantly change from heeled to flats.
Visible crew/equipment: Whilst the group of Southeast Asian men are walking through the hair salon, there is a shot that starts with a male hairdresser wafting a blanket, that pans over to the group of men and then the camera rotates around the man holding a little girl. Immediately after the camera passes the man and girl, the camera very briefly holds on another man waving to an employee. Just as this happens, the reflection of the cameraman can be seen in the mirror to the left of the shot. (00:31:30)
