Revealing: When dead Jackie Boy is talking to Dwight, you can see his normal neck under the fake slit-throat neck, and once or twice, you can even see a little device that was meant to shoot out smoke from a cigarette in the fake appliance.

Continuity: When Nancy is dancing, she is alternately wearing/not wearing gloves between shots.

Continuity: The blood on Marv's chin appears and disappears when he's being interrogated by Wendy and the girls.

Continuity: When Lucille throws the pills to Marv, he catches it with his left hand (while holding a cigarette in his right hand). The shot changes immediately to a close up on the pills in Marv's right hand. Then in the next shot Marv takes the pills, but has to take the cigarette out of his mouth first.

Factual error: In the scene where Bruce Willis is confined in the hospital, where he is talking to young Nancy, a volume respirator can be heard, yet Willis is not intubated and no other paraphernalia are attached to his larynx and only intravenous lines are present.

Factual error: When Marv is talking with the Priest in the confessional, he cocks the hammer of his pistol as a means of interrogation. But in the next shot, the pistol is uncocked, without sufficient time for this to occur. In fact, the pistol is uncocked even when Marv shoots him. This cannot happen, since his pistol is a standard 1911 .45, which requires the hammer to be cocked in order to fire.

Continuity: When Marv and Wendy are driving to the farm to take out Goldie's killer, Marv is smoking a cigarette, and it's in his mouth, but when the camera cuts to a close up of their faces, the cigarette is in his hand.

Continuity: Dwight is tossed into the tar pits and submerged. In the next shot however, his head is back above the tar, and his face is fairly clean.

Continuity: While Dwight is searching Jackie Boy's corpse, the blood around him changes once or twice. It goes from no blood, to some blood, to no blood, to a whole giant puddle full.

Continuity: The amount of cigarette burned up in the scene with Marv and Lucille in the bathroom, changes several times.

Continuity: When Hartigan is being beaten before going to jail, there is a close-up of his face. There is a five-inch long, one-inch wide rip in his right cheek. Even though he has scars already on his forehead, this damage just disappears afterward.

Continuity: The amount of blood spewing from Jackie Boy's arm, after his hand is cut off, changes between shots, just before Miho kills his friends.

Continuity: When Marv pulls back the top of "Gladys" (his gun) in his old bedroom, the top is suddenly shut in the next shot. (Extended Edition DVD).

Continuity: When Marv is interrogating the priest, in one of the cuts, his finger goes from being above the trigger, to being right on the trigger.

Revealing: In some shots towards the end when it's snowing, you can see the snow (computer generated) simply disappear, especially in over-head shots. It isn't hitting the ground, it just disappears.

Revealing: When Marv is starting to dunk the man's head into the toilet, trying to get more information, you can see the rim of the toilet flex slightly from his weight.

Continuity: When Yellow Bastards "weapon" is taken away, the position of his head changes between several shots. He goes from looking at Hartigan to leaning back screaming between some of the shots.

Continuity: When the female Irish assassin sees Jackie Boy's dead body, in the first shot she is starting to grab the window of the car, but in the next shot, her hand is no longer holding onto it.

Continuity: In the bathroom scene, as Marv stands up, Lucille's arm (holding the cigarette) goes from pointed up in the air to being down by her side, between shots.
