Continuity mistake: After Mia has recovered from the overdose, Vincent carries her to her house. As they are walking in the small alley, the camera shows Vincent saying, "If Marcellus lives his whole life he doesn't need to know about this incident," and he opens his arms. In the next shot we can see Vincent from the back and he has his arms in a different position. (00:59:10)
Continuity mistake: When Butch is getting dressed in the motel room, Fabienne is sitting on bed telling him what she will order for breakfast. As she tells him, in a front shot of her, her right arm is down and her right hand is resting on her ankles. It then cuts to a behind shot of her and her head is now resting on her right hand. (01:20:45)
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).
Factual error: When Vincent shoots Marvin the bullet goes through Marvin's head and exits out the back of his skull with explosive force - enough to splatter "pieces of brain" all over the back of the car. If it exited with so much force the rear window of the car should have shattered from the bullet, but it doesn't even get chipped.
Continuity mistake: After Butch crashes the car, he stumbles down the sidewalk with Marcellus staggering behind him. When the camera is directly behind Butch, cars are seen traveling down the street in the opposite direction. In the next shot, behind Marcellus and with Butch in the distance, the cars have disappeared.
Continuity mistake: After returning from Jackrabbit Slims, Vincent goes to the toliet and Mia puts on some music, then sits on the couch. In one closeup of Mia, she takes a cigarette and puts it in her mouth, and you can see she isn't wearing Vincent's grey jacket. Then when it cuts to a wider shot of her lighting the cigarette, the jacket has appeared on her. (00:50:25)
Continuity mistake: In the scene at the diner at the end of the movie, Vincent is cutting pancakes with the knife in his right hand, fork in the left. When he begins laughing at the "Arnold on Green Acres" comment, he puts his head down onto the back of his right hand which now has the fork, but he never switched utensils.
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.
Audio problem: The Philip Morris bellboy in Jack Rabbit Slim's does the famous "Call for Philip Morris." while walking away from the camera. When he turns to the side and does the call again, we can see that his mouth movement doesn't match the vocal.
