Visible crew/equipment: When Officer Romero and Arthur are alone in the house, handcuffed to the brass shelving unit, as she says, "Help me or I will crush you like a damn bug," a crewmember wearing glasses and a blue shirt is seen crouching on the floor, at the bottom right of the screen. (00:53:05)
Continuity mistake: In the restaurant scene where the cigar dispute takes place, Bruce gets his fingers broken on his right hand. Later on in the movie, the two FBI agents encounter Bruce in his yellow Hummer. When he rolls down his window, his bandaged LEFT hand is shown.
Visible crew/equipment: When Desalvo, Ferroni, Matt and Andrew are all in the backyard waiting for their moments to strike, in the exterior shots facing the back doors, Arthur is standing facing the TV and there is a small beige rug between him and the TV which disappears in following shots. (00:16:10)
Continuity mistake: When Eliot is coming to get his son after the missed murder attempt, he enters the room and walks towards his son then is nearly beside him. After it cuts to Anna, when it cuts back to Eliot, he is again walking toward his son. (00:19:45)
Revealing mistake: About 30min into the movie, there is a scene at an airport with a 4-engined 707 freighter. As the characters walk behind the jet, you can see that the left-hand inboard engine pod has no engine on it, unlike the outboard pod. The aircraft is obviously being dismantled despite the appearance of having just landed.
Continuity mistake: When Snake falls toward the water with the "kingpin's suitcase", the gun is in his right hand and he's gripping the heavy suitcase in his left hand. Yet, in the last shot of him underwater the gun and suitcase have switched hands. Interestingly this is not a flipped shot, the watches are still on his left wrist. (01:14:10)
Continuity mistake: When Stanley Tucci throws his wallet at Tom Sizemore in the bar's robbery scene, the wallet hits Sizemore in the face, then hits his upper arm, then falls behind him to his right. Yet, in the next shot, it has landed on the bomb case on the floor to his left. The same thing happens a few moments later when Tucci throws his keys at Sizemore. (00:40:04)
Continuity mistake: When Puggy is at the bar, and the bartender gives Puggy his change, the money is either closer to him or farther away between shots.
Continuity mistake: When Snake sees Eliot in the airplane terminal, he shoots at him once, shattering only the top half of the glass door (which is split in two by a metal bar). Eliot then leaves the terminal heading outside. He ducks under the bar and through the door to go outside.
Plot hole: When the pilot rolls the plane to dump the suitcase carrying the bomb, Snake grabs hold and falls out of the plane with it. Snake saves himself from falling to his death by grabbing the railing of the open door. The weight of the suitcase would have either ripped one of Snake's limbs off or would have ripped the railing from the door.
Factual error: When the Dalmatian and her new puppies are shown, the puppies are standing and their eyes are open. However, a new born puppy's eyes are sealed shut until they are at least 12 days old and they can only crawl on their bellies. (00:05:19)
