Continuity mistake: When Mr. White is trying to calm Mr. Orange in the warehouse White pulls out a comb and uses it on Orange then goes to put it in his pocket, but lays it on Orange's chest and never picks it back up. In the next sequence when talking to Mr.Pink, White washes his hands and face, puts some water in his hair, pulls a comb out of his pocket and uses it. (00:13:05)
Suggested correction: He combs his own hair and Mr. Orange's when neither are necessary. Can definitely see a guy like that carrying more than one comb. They don't take up much pocket space anyway.
Continuity mistake: In the scene where Mr. Pink is running away from the police, he gets hit by a car. He pulls the woman out of the car and leaves the bag on the ground. The shot changes to the police, then back to him and the bag is gone even though he's still trying to open the door. (00:21:00)
Continuity mistake: Just after Mr. Pink stops Mr. White and Mr. Blonde from fighting, watch Mr. Blonde's tie. It's secured with a tie pin - initially rumpled so the top bit "bumps", then smooth for a couple of shots, then back to having a bump. (00:34:00)
Continuity mistake: During the flashback of Mr. Orange's "commode story", Orange presses the button to start the hand dryer with one finger and the rest of his fist clenched. In the next shot, his thumb is instantly extended, as well. (01:13:10)
Continuity mistake: In the scene where Mr. Blonde is pouring gasoline over the cop, the cop's legs are flying around trying to kick him. Later, we see that the cop's legs are still taped to the chair.
Continuity mistake: When Mr Blonde cuts the ear off the cop, we cut to a shot of him holding the ear, it is covered in blood. However, when we cut to a shot of Mr Blonde talking into the ear, there is no blood on the ear.
Continuity mistake: There is a scene where the cops are chasing Mr. Pink. Keep an eye on the hardware store which is followed by a grey building with a sign each side of a door - Mr. Pink runs past it, then the cops run past it, then Mr. Pink runs past it again.
Continuity mistake: When they bring Marvin Nash to be tortured, his hands are cuffed behind his back. They start kicking him and his hands are then seen cuffed in front. Then, they switch back just a few moments later and his hands are back behind his back again.
Continuity mistake: During the torture scene, Mr. Blonde gets his sleeves bloody, but when he is holding the ear, the blood disappears. A few seconds later, the sleeves are bloody again.
Continuity mistake: When Mr. Blonde is in the warehouse with the cop, it shows close-up of the cop, and he has blood on his forehead on the left side. After Mr Blonde slaps him in the face, the blood has disappeared. It reappears later.
Continuity mistake: During Mr. Pink's flashback, he's chased by three cops across the sidewalk of a long, straight avenue - apparently, they all pass the same exact spot numerous times. Notice the white van parking next to the sidewalk as the policemen run next to it - it is followed by a yellow truck. Look closely beneath it, and you'll spot a place where the sidewalk mixes with the road. Later on, in the wide shot of Mr. Pink running, he passes next to the same exact white van, and the same spot where the road mixes with the sidewalk is visible just next to it, right as he picks up the briefcase behind it, yet the yellow truck is gone. Since the cops are behind him, that place should be far away, as he's been running along a long avenue. [To make the street look longer, the filmmakers shot the chase a few more time on the same short street to make it look like a long avenue. Yet the white van marks the same spot, and thus it is a mistake.].
Continuity mistake: During the chase, we see that there are only three cops (we see a head-on shot of the three cops with an empty sidewalk behind them), but when Mr. Pink opens the car door and starts firing in the direction of the cops, the first three cops (the thin ones) scramble back around the corner. Just then, a fourth cop (the fat one) pops around the corner from nowhere and gets shot.
Continuity mistake: In a flash back scene, Mr Blonde and Nice Guy Eddie are about to play fight. However, when they hit the floor, they have both changed sides, even though the way they were going for each other showed they would not fall opposite sides.
Continuity mistake: After the climactic shootout near the end of the movie, Mr. White falls on his elbows, facing Eddie's body. In the next shot, Mr. Pink leaves. When he is leaving, Mr. White is facing the back of the warehouse, where Mr. Pink hid. That is a near 45 degree turn when Mr. White was in both shots.
Continuity mistake: When Mr. Pink and Mr. White reflect on Mr. Blonde's madman behavior during the robbery, Mr. White says "I came this close to taking him out." A few minutes later, that line is unintentionally attributed to Mr. Pink. It happens just after Mr. Blonde arrives at the warehouse with his soda, when he and Mr. White nearly get into a fistfight. As Mr. Pink moves to stop the fight, Mr, White says something to the effect of, "Now you're taking his side?" a few minutes ago, you said you thought about taking him out." An incredulous Mr. Blonde says "You said that?" Mr. Pink admits that he did, even though he didn't, but now maintains that Mr. Blonde is the only one he can trust: "He's too homicidal to be working with the cops." This mistake is caused by QT changing the original script (where the "I came this close" - line was originally for Mr. Pink) but forgetting to also alter the later reference.
Continuity mistake: In a scene near the end, Joe arrives at the warehouse and tells everyone that Orange is the informer. We frequently see Orange on the floor, however the blood patch he is lying in changes from wet to dried to very wet to larger and smaller and back and forth. Also sometimes there are bullet casings around him or the magazine he dropped depending on the shot.
Continuity mistake: In the "Mr. Blonde" segment, Vic takes a cigarette from a case on Joe's desk and puts it in his mouth. Soon after he takes it out. Then there is a shot from the hallway and the cigarette magically appears back in his mouth, where he takes it out for a second time.
Continuity mistake: When Nice Guy Eddie (Chris Penn) shoots the cop tied in the chair at the end, watch where Eddie points the gun, as opposed to where the blanks explode in the cop's chest. Where Eddie was pointing the gun, he probably would have shot the cop in the crotch.
Continuity mistake: During Mr. Pink's flashback, as he's being chased by the three cops, he pushes a man with a grey jacket aside as he comes between him and another man; in one shot, the man with the grey jacket falls onto the ground, but in the next angle, he just moves to the side.
Continuity mistake: In the scene where Mr. White and Mr. Pink get in a fight and draw their pistols, you hear both of them pull the hammer back. In the next shot, the camera is behind Mr. White, looking down at Mr. Pink. You can see that the hammer on his pistol is down, not up.
