Continuity mistake: At the beginning of the film, when Jack is playing Jenga with the teenager, Jack crosses his arms twice. (00:01:45)
Continuity mistake: When Paul is introduced at the hospital, in one shot he thinks, "What am I doing in this precorpse club?" and turns his head to his left. In the next shot, he is turned to the right, and the shot after shows him turning from his left to his right. (00:04:45)
Continuity mistake: As Cristina hangs up on Ana at the bar, Cristina's left arm shifts from across her lap to across her chest. (00:41:00)
Continuity mistake: Inside the church, when everyone's singing "I've got a river of happiness" (or something like that), Benicio Del Toro exchanges glances with a young man. Watch the black man to the right of Del Toro, his mouth is in no way synchronized to what the people are singing. (01:23:15)
Continuity mistake: Cristina switches from looking down to looking at Paul after he throws his cigarette out the window in the car outside her house. (01:33:35)
Visible crew/equipment: When Sean Penn is outside the motel with the gun, he fires three shots past Benicio Del Toro's head into the ground behind. When Benicio falls to the ground you can see an ear plug in his left ear. (01:49:05)
Factual error: In the movie, Cristina declines to press charges so Jack goes free, but it's the District Attorney who decides whether charges are pressed on behalf of the state.
Factual error: Holding hot metal - ie: the butter knife Benicio Del Torro uses - against your skin would not do any damage to a tattoo, tattoo ink is a mixture of fine metal powder and ink injected beneath the surface layer of the skin. If anything burning the skin actually makes tattoos sink deeper. The removal process is not heat as people think, it is the superheating of the metal in the ink, causing it to explode.
Continuity mistake: Right before Sean kills The Man he pulls out a silver gun and puts it in his pocket. Later on in the movie he has a black gun.
Suggested correction: The gun only appears silver in certain shots. This is because of the lighting and angle of the gun and the fact that it is - as are all guns - covered in oil to protect it.
