Continuity mistake: About 10-15 minutes from the end, Bill and The Bride are talking in a room with a round couch with pillows on it. The Bride goes to sit down on the couch and directly behind her there is a striped pillow. As she sits, you can see that when she leans back, she will lean onto the pillow. However, the shot changes and as she completes leaning back, the pillow is no longer behind her, but to the side so that she leans against the back of the sofa.
Continuity mistake: During the end, when the Bride is talking to Bill, as the camera changes, the position of the Tequila bottle cork changes from lying on its top to its side.
Continuity mistake: A deleted scene in the Kill Bill 2 menu reveals a showdown between Bill and a black man with four henchmen. First henchman goes down then the remaining three attack. Bill slashes at them and they go down. As Bill approaches the black man, the positions of the three recently slaughtered henchmen changes everytime they are in shot.
Continuity mistake: After Budd shoots Beatrix, he walks to his chair, places his "cup" (an empty Jar) on a makeshift table and sits down. As he does so, the jar switches hands in-between shots.
Continuity mistake: There are two shots of Elle driving up to Bud's trailer - in the first she drives straight and skids to a stop in front of his door, and in the second (which we see from the Bride's point of view up on the hill) she turns and pulls in before reaching the trailer.
Continuity mistake: In the scene where Bill is telling what happened to Amelio the fish, the bites in B.B.'s sandwich keep changing.
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 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: 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.
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: When Uma is talking to the Spanish pimp guy towards the end, his cigarette length changes throughout the scene.
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.
