Continuity mistake: In the scene when Bill drops off the bride with Pai Mei, and they are talking by the truck, her jacket goes from around her elbows to on her shoulders without her putting it on.
Continuity mistake: When Beatrix is putting Elle's head into the toilet bowl in the fight you can see Elle is holding the toilet basin near the left edge with her left hand very tightly (you can tell its hers by the black sleeve). In the next shot she is bringing her hand up from below the basin around the middle of the left side and grabbing Beatrix's arm. Even if she dropped her hand there was not enough time during the shots for her to drop her hand from the basin and bring it back up. (01:13:20)
Continuity mistake: When Beatrix squishes Elle's eyeball with her foot she is in the threshold of the door. The next shot she is halfway down the hall and picking up the Hanzo sword. We do hear Elle in the background and her screaming is continuous. Beatrix could have never gotten from the threshold of the door to halfway down the hall that quickly. (01:20:10)
Continuity mistake: When Uma Thurman is at the trailer and is shot by Budd, then injected with a drug, there is a close up of her face and hands as she is injected. she clutches some sand in her hands which are under her head and her head drops onto her hand. However in the next shot when Budd is calling Elle on his mobile, if you look at Uma in the background her hands and arms are either side of her head and quite widely spread apart.
Continuity mistake: At the beginning when Uma Thurman is talking to David Carradine, the ring on her finger moves slightly. At first it's worn normally, facing directly towards Carradine, but then in the next shot, it's facing down.
Continuity mistake: After Beatrix plucks out Elle's other eye, Elle begins to kick and flail in the bathroom. A shot of the toilet has magazines and bottles neatly on top of it. The next shot the bottles are tipped over and the magazines are on the toilet seat. Elle never got close enough to the toilet to knock these items over. A few shots later and the magazines that were on the toilet seat are no longer there. (01:19:55)
Continuity mistake: When the Bride finally confronts Bill in his apartment, B.B. "shoots" her in the doorway. The Bride spins from the pretended impact to her left, but in the next shot she's centered in the doorway again.
Continuity mistake: When Daryl Hannah and Michael Madsen are talking in his trailer, as he says "Horsesh*t" he holds drink at his chest. Cut and his arms are both in his lap.
Continuity mistake: During the fight in Budd's trailer, the Bride tries to drown Elle in the toilet. As she's falling to the right, you can see that the magazines (that were previously on top of the tank) have somehow moved to the seat. An instant later, they're gone. (01:16:10 - 01:20:00)
Revealing mistake: When they show a close up of Pai Mei's face, look at his eyebrows. You can see the actor's real brown eyebrows underneath the fake white ones.
Continuity mistake: After Budd is done pouring the two drinks and the little speech to Elle about comparing Hanzo swords, he closes the door of the overhead cabinet with the blender in his right hand, then he puts the blender down, practically throwing it to the counter next to the Margarita Mix bottle. When he walks over to hand Elle the drink, the shot from behind the counter shows the blender is not where it's supposed to be, only the bottle.
Continuity mistake: When The Bride is in the coffin, various aspects of it keep changing. When the lid's being nailed on, one shot shows the wood a bit warped to the left of her head (where a nail's too close to the surface) but in other shots it's fine. The grain also changes in places, most noticeably when she's punching her way out - in different shots there's a knot to the left on the blood stain, above it, or right under it.
Continuity mistake: When Beatrix lies in bed with B.B. she has a doll up against her chin. But in the next shot, the doll has suddenly moved away and her arm is next to her face.
Continuity mistake: In the scene where Beatrix is fighting Elle in Budd's trailer, she removes an aerial from the TV and slashes Elle's face, leaving four large gashes. In the next shot, two of the wounds are gone. (01:14:15)
Continuity mistake: When Uma is talking to the Spanish pimp guy towards the end, his cigarette length changes throughout the scene.
Continuity mistake: When Budd is talking to Bill, 1/4 of the razor blade on his necklace is tucked in his shirt. In the next shot is completely out of his shirt. (00:17:45)
Continuity mistake: At the end of Volume 1 when Budd says "That woman deserves her revenge" the caravan door behind him hinges on the right, yet throughout Volume 2 it hinges on the left.
Continuity mistake: When Bea takes the truth serum shot out she throws it to the ground. When Bill sits down it's on the table in front of Bea. When the shot goes back to Bea and then back to Bill, the dart is facing the opposite direction.
Continuity mistake: When Beatrix arrives at Bill's hacienda, the sword on her back is Budd's (different handle with cotton wrap). She retains Budd's sword until Bill takes it, at which point it is her sword again.
Continuity mistake: After Bill shoots the fruit in the truth serum scene, there is a tented fold in the couch's fabric, to the right of Beatrix's right shoulder as she begins scooping fruit from her chest. Then it's gone. Tented fabric reappears. Then is gone again.
Chosen answer: The way she talks to Budd as he lies dying, seems to indicate that she has disliked and hated him for years, plus the fact that she feels that he was not "worthy" of killing Kiddo (seeing how Kiddo was a fantastic warrior, while Budd is an alcoholic hick). However, it would be difficult for her to get close enough to kill him earlier, as he would not buy any excuse why she just came visiting. But when Budd actually invites her over, she gets a chance to get back at him, and in the same while take the credit for killing the Bride and retrieving her Hanzo sword for Bill. Vengeance and personal gain in one swoop.
