Corrected entry: When Mia Wallace has discovered Vincent Vega's heroin and thinks that it is cocaine, she makes a line, then snorts it. She realises that it is not what she thinks it is and starts to moan and rub her nose. You can tell that Mia is trying to break the blood packet in her nose because at one point she sticks her finger up her nose and pushes hard on something and it takes a couple of seconds of her rubbing her nose to produce any blood.
Corrected entry: When Jules and Vincent are loading in their guns in the beginning of the film, Jules drops the hammer on his pistol. He does it almost effortlessly, despite the gun supposedly being loaded. The gun he uses is a Star Model B (a 9mm copy of the M1911), which has a hammer, and one SHOULD NEVER drop the hammer on a live round with a 1911 or any hammer fired pistol. Even if done, extreme caution should be exercised, but still shouldn't. He is doing the same when he lets "Ringo" go at the diner.
Corrected entry: Whilst travelling in a car with Samuel, John accidentally shoots the man in the back seat. He and Samuel carry on talking. You just can't fire a high calibre gun in an enclosed space and not have a hearing problem.
Corrected entry: In the scene where Vincent, Jules and Jimmy are having coffee, there's a time interval about two minutes long between the first and the last times we see the wall clock behind Jimmy. Given the type of the clock, you would expect its minute hand to move during the scene, but apparently the clock was stopped during the shooting. If the non-working clock were supposed to be part of the plot, it would be quite a coincidence that it shows the correct time for the scene.
Corrected entry: When Samuel L. Jackson is talking with Tim Roth (who is holding a gun on Jackson) at the restaurant we see a closeup under the table of Jackson taking out his 9mm gun with his right hand. But moments later he takes the briefcase with the same right hand and places it on the table between them. Then seconds later Jackson pulls Roth's gun arm down with his left hand and toward him, pinning it for a moment - while at the same time Jackson suddenly pulls out from under the table *his* 9mm gun. Does he have three arms like the alien from Venus in the famous "Twilight Zone" diner episode? If he had placed it down on the seat to his right, wouldn't HoneyBunny standing over them a few feet away have seen it? If it was on the floor, he didn't reach down nearly enough to retrieve it. If it were in his shorts (as he placed it while walking out of the diner with Travolta a few minutes later) he would have had to reach down while sitting, pull it up and out and by that time, Roth and/or Honeybunny would have had three bullets in his head. It was an obvious director's sleight-of-hand, so to speak - a cheat that didn't make visual/time sense in order to surprise the audience - along with Tim Roth.
Corrected entry: When Jules is explaining what would happen if Bonnie came home to find them dealing with the dead body, the camera follows her from outside to the kitchen. When she walks through the front door of the house, she leaves the front door open. This is obviously so the cameraman can walk through behind her, but it's not logical for her to just lazily leave her front door open. (01:55:45)
Corrected entry: In the very first scene with hunny-bunny and pumpkin when they decide to rob the restaurant, hunny-bunny says "Any of you f**king pricks move and I'll execute every motherf**king last one of you." However, at the end of the movie with Vincent and Jules, when the scene is repeated she says "Any of you f**king pricks move and I'll execute every one of you motherf**kers." Also in the second scene it takes a few seconds longer for her to take out a gun out of her purse.
Corrected entry: Marcellus Wallace is bound and gagged while being sodomized by Zed. Butch makes the save by killing Maynard and holding the sword to Zed. Marcellus then shoots Zed with a shotgun. However it is never revealed how Marcellus becomes untied. His bonds had to have been good and tight in order for Zed to have his way with him.
