Continuity: When Luc and his gang barge in on the wedding, in one shot the bride is facing forward, but in the next shot, her head is turned to look back, and then turns back forward.

Revealing: When the bugs are flying into the bug zapper in the bar, the sparks on the bug zapper are far too big to be real, and are obviously small squibs set up on the zapper.

Revealing: When War executes the wedding witnesses, we can see several people behind Lola, cowering behind a table, and they don't react at all when the shots are fired.

Revealing: After Luc says "God is finally paying attention" at Rave-N-Fest, you can see an extra in the background, smiling in the next shot, which makes no sense after all the chaos that just ensued.

Revealing: While at the wedding chapel, a shot is fired off camera in the other room, and we see the flash of the gun light up much of the chapel. But gun flashes aren't big enough to emit such light.

Continuity: During the fight at the bar, when Jimmy and the bartender are fighting, the stances and position of their bodies change between several cuts.

Continuity: When the crow lands on the ceiling-fan in the bar, its position changes between shots. It goes from being about halfway down the fan-blade to near the end.

Continuity: When Jimmy is electrocuting Pestilence, in some shots he has both hands on Pestilence's neck, and in others he has only one hand around his neck.

Audio problem: When Pestilence puts the bug in his mouth, we hear a crunch as if he is chewing it, yet a few seconds later he spits it out and it is not chewed up at all.

Continuity: When Pestilence is being soaked with toxic chemicals in the beginning, in the shot where it does a freeze frame, his body is soaked in the chemicals, but he has not been exposed to the spraying chemicals enough for so much to have covered him.

Continuity: When Pestilence drives up and gives war the "Rock on" sign in the beginning, he is driving by some debris and junk in the first shot, but during his closeup in the next shot, he is suddenly in front of a metal fence that wasn't around in the previous shot.

Plot hole: Why would so many toxic chemicals be used in coal mining, and used as close to the miners as illustrated in the film?

Continuity: When War's truck drives out of the mine in the beginning, at first there are protesters a good ten feet away waving signs, but in the closer shot one of the protesters is waving a sign just about a foot or so away from his truck, without having any time to get closer.

Audio problem: The mine workers are chanting "Save our jobs" in the beginning, yet their mouths never match what they are saying.

Continuity: When Pestilence kicks the barrel in the beginning, in one shot it is falling over and rolling a little bit, but in the next shot it is suddenly perfectly still.

Continuity: When he is killing Jimmy and Lilly, the amount of Death's cigarette that is burnt up changes between some shots.

Deliberate "mistake": You can tell the miner uniforms and prisoner uniforms are exactly the same wardrobe, the prisoner uniforms are simply marked "Prisoner" to make them seem different.

Continuity: When Famine is about to punch Jimmy in the stomach in the beginning, he starts to put his hand on Jimmy's shoulder, but in the next shot it is already on his shoulder and he is swinging his arm to punch Jimmy.

Revealing: When Lola is cutting out Lily's eyes, you can tell from her movements that she is not really cutting them out.

Continuity: When the guys are spray-painting words on Jimmy's trailer, as they run away the man on crutches is suddenly much farther away when the camera cuts.
