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)
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: 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 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: 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.
