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.
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.
Deliberate mistake: When Butch is riding in the taxi and smoking, the cigarette smoke is lazily drifting out of the window of the vehicle. If they were traveling at any real speed (i.e. not on a set with a movie screen behind it) their smoke would be ripped out of the taxi by the wind. Also, when he tosses out some of his stuff you can hear it hit the wooden floor of the stage. (01:12:28)
