Deliberate mistake: Both in the first scene and last scene of the movie, we see Yolanda and Ringo starting the robbery by jumping from their seat and start threatening the costumers. In the first scene, Yolanda says "And I'll execute every motherfucking last one of you." But in the last scene the line changes to "and I'll execute every one of you motherfuckers". (00:04:40 - 02:18:00)
Suggested correction: Tarantino has explained that this is not an error, rather, he did this on purpose. When we first examine the scene, we are seeing Ringo and Yolanda's conversation from their perspective. Obviously, because this is their conversation, what we hear first is probably what was actually said. However, at the end of the film, what is said is different because we are no longer viewing the situation from Ringo and Yolanda's perspective, but rather everyone else in the diner, most specifically Jules.
Sounds like a typical Tarantino excuse for a stupid blunder.
I believe about 70% of the so-called mistakes called out here are really cinematic techniques to show points of view, highlight significant action, and underscore dramatic moments.
Continuity mistake: At the beginning, when Brett is initially shot by both Jules and Vincent after Jules' Ezekiel speech, we see Jules' gun becomes empty on firing the last shot. However, on returning to the same scene at the end, when Jules and Vincent shoot Brett the gun does not empty; in fact Jules is able to repeatedly shoot the guy who comes out of the bathroom afterwards and the gun still isn't empty.
Suggested correction: It's very hard to tell whether Jules' gun is empty or not, he is pointing it almost right at the viewer, and the scene is proceeding too rapidly.
It's easy to tell. You can see the slide is locked back in the first scene, indicating it's empty. If you can't see the slide is back, look at the ejection port. It's grey/silver color when the slide is forward (i.e. round in the chamber) and black when back (i.e. empty).
Visible crew/equipment: When Vince and Mia get back from Jack Rabbit Slims, and Mia is putting on the music, the shadow of a person walks past her on her left, but Vince is standing still in that scene. (00:48:35)
Suggested correction: I've viewed this mistake many times. What really happened here was Vince actually turned and walked down the hall to take the piss and what we are seeing is HIS shadow as he walks toward an over-lit backdrop. Then to make it worse the producers place him right back at the spot with his keys in hand and a softer lighting to make it look more romantic. So the real mistake could be when they made that sudden change without reviewing enough of the previous entry scene. (Either way you can still barely see how he turns to his right before walking casually down the hall).
Continuity mistake: Lance is sitting at home eating cereal and watching the end of a Three Stooges short, "Brideless Groom," on television. During the subsequent phone conversation between Lance and Vincent, we can hear the short's soundtrack continuing in the background. The soundtrack then abruptly changes to an earlier scene in the short (Christine McIntyre slapping Shemp around) and then to a different short altogether ("Sing a Song of Six Pants," with Harold Brauer talking about a safe combination).
Suggested correction: "Brideless Groom, Sing a Song of Six Pants, and Disorder in the Court" are all 3 featured on the same single copy of a DVD release of The Three Stooges (I own it). Trudy, the one WITHOUT all the "stuff" in her face, is still seen in the same room watching the TV also. She very easily could have changed scenes with a single click of a remote, as the camera is not focused on her during the shots of Lance on the phone with Vince.
94, no DVD.
Continuity mistake: Towards the end of the movie in the coffee shop scene, we see Samuel L. Jackson holding up his wallet, waiting to deposit it into the bag, it is very apparent that there is no writing on this wallet, it is a fat, and barely able to stay folded, yet when Ringo is instructed to retrieve this wallet, the one he brings out is now the one that says "Bad Motherfu**er", it is very slim, and a darker brown.
Suggested correction: It's very obvious, that wallet actually has writing on it, and it can be seen very good in the exact moment, when Jules is taking it out from the pocket. The wallet is the same, only stuffed better.
Deliberate mistake: Jules' famous Ezekiel quote is actually an expansion of what is in the Bible. Ezekiel 25-17 actually reads: "And I will execute great vengeance upon them with furious rebukes; and they shall know that I am the Lord, when I shall lay my vengeance upon them." (00:20:10 - 00:22:25)
Suggested correction: Any wrong-spelled quotes that been said by any character can't even be remotely considered as a movie mistake, character can basically say anything he wants and mistake in any quotes by will as any living person can do.
This mistake is referring to the beginning of the quote, the "path of the righteous man" part. Those few sentences are nowhere in the bible. Jules begins his quote by stating Ezekiel 25:17, but the only part of what he says that's in that verse is the "great vengeance and furious anger" part. Everything else Jules said was added by Quentin Tarantino, which would make it technically a misquote, and thus a Deliberate Mistake.
Continuity mistake: When Vincent and Jules are at Brett's apartment at the beginning of the movie, Jules takes the hamburger from Brett's table after he asks to taste it. The hamburger in the first shot simply contains cheese and ketchup, but when Jules bites it there is only a leaf of lettuce. Moreover, the hamburger appears first intact, but in the next shot it appears already bitten.
Suggested correction: The cheese is there when he bites into it, and there is only a piece of lettuce sticking out on one side, a side you don't see when he picks it up. You also can't see if there already was a bite taken out from that angle. My guess is, it's the same burger, no reason for it to be otherwise. When it only "appears" intact, it doesn't mean it is.
