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: 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: Only in Germany is a McDonald's Quarter Pounder known exactly as a "Royale with Cheese" ("Royal mit Käse"). The closest otherwise is the French or Portugese "Royal Cheese" but Jules specifically mentions Amsterdam, and a Quarter Pounder with Cheese in Holland is just a Quarter Pounder with Cheese. Many countries which use the metric system don't bother renaming products that use imperial measures. It's a Quarter Pounder with Cheese in Australia, too. Vincent's observation about "Royale with Cheese" being the name of the quarter-pounder with cheese in Amsterdam applies - albeit to Germany, where this has been the official name of the burger for 40+ years.
Corrected entry: After Butch leaves his apartment and is stopped at a stoplight, Marsellus stops in front of the car and Butch attempts to escape, in the process hitting Marsellus. When Marsellus stirs, his eyes flutter open once and you can see that his eyes are blue. Except, when he stands up and says, "I'll be damned." it is clear that his eyes are a dark brown. (01:34:55)
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.
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.
