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.
Audio problem: In the scene when Mr Blonde comes to the warehouse and asks Mr White if he's going to bark all day, Mr Pink rushes in to break them up and right after he says 'calm the f**k down', he says 'hey come on' but his mouth doesn't move.
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.
Continuity mistake: During Mr. Pink's flashback, He shoots the four cops hiding behind the corner while jacking the car. When looking from Mr. Pink's point of view, you can see that the fat cop gets shot and leans on the ground, yet when we see this from the policemen's point of view, the fat cop isn't injured and fires without a problem, when suddenly he gets shot.
Continuity mistake: In the scene where Mr. Blonde cuts off the cop's ear. When he pours the gasoline over the cop, you can see his ear is complete and on his head.
Continuity mistake: Mr. Blonde, in a gory display, removes an ear from a police officer. He then drops it onto the ground, and goes to get gasoline. In the next scene, the ear on the floor is missing.
Continuity mistake: When Mr. White and Mr. Pink go into the back room at the warehouse, Mr. Pink is about to sit on a chair, and has his cigarette is in his hand. But when the camera angle changes (when he is sitting down) the cigarette is in his mouth.
Revealing mistake: When Mr. Orange shoots Mr. Blonde in the warehouse, you can see that the rounds rolling down the ramp are blanks.
Continuity mistake: In the scene where Quentin Tarantino crashes the getaway car into the back of a parked car (as he, Tim Roth and Harvey Keitel are fleeing the robbery), the car screeches around the corner and crashes, and you can see, from many different angles, that there is only a driver: no-one in the back seat. Yet, the next shot shows Tim and Harvey experiencing the collision as they are sitting in the back seat.
Continuity mistake: When White, Pink, and Eddie return from retrieving the diamonds to find a dead Mr. Blonde, Mr. Pink walks around the body and then there is a close-up of Blonde where Pink's legs can be seen walking around the body a second time.
Continuity mistake: After Mr. Orange passes out, Mr. Pink and Mr. White go into the next room to talk. Then there is some cutting back and forth to different angles of the conversation they have. When it is filmed from behind them, there is a chair in the foreground that should be visible from the larger hall where Mr. Orange is still lying, but when the angle is back to the large hall, the chair is nowhere to be seen.
Revealing mistake: When Mr. White shoots the two cops inside their car and Mr. Orange watches the scene astonished, dummies replacing the cops are visible for half a second sitting inside the vehicle just before the windscreen gets hit by the bullets.
Visible crew/equipment: When Mr. White and Mr. Orange run away after Mr. Brown's death and killing the cops, crew members are visible in the background hidden behind the truck.
Visible crew/equipment: When Mr. Pink escapes from the cops and he's hit by a car, you can see the crew members in the background watching the scene.
Factual error: During the flashback of Mr. Pink escaping, he smashes a car window and the window shatters into several large pieces. Car windows are made of tempered glass, which shatters into hundreds of small pieces.
