Immediately before the Bride awakes from her coma, there is a buzzing mosquito that lands and bites the Bride. The sound played is that of a common housefly, whereas in actual fact the beating wings of a mosquito produce a constant, almost perfect F-sharp.
When O-ren Ishii's motorbike guard is in the tunnel, you can hear the pitch rise and drop. The first time this happens, the motorcycle is at a fixed point with respect to the camera. In reality, the sound implies that the source is moving toward and then away from the observer, due to the Doppler effect.
When The Bride is in the back of Buck's Pussy Wagon, she says, "As I lay in the back of Buck's truck, trying to will my limbs out of entropy... ." The term that should have been used would have been atrophy, not entropy. (Some argue that entropy is perfectly acceptable as a term describing disrepair or disorder: actually, by the second principle of thermodynamic, "entropy" is just the tendency of a thermic system - thence a human body - to release heat and energy into outer ambient when not restrained).
In the "Origin of O-Ren Ishii" sequence, during the introduction of the character Sofie Fatale, the voice-over says Sofie is to O-Ren's right, when actually Sofie is to the camera's right, or O-Ren's left.
When we see the death list for the first time, all the people's names are written in red ink, later when we see her drawing a line through O-Ren's name the names are in black. Then when the Bride is seen to be writing the list on the plane, near the end of Volume one, she uses red ink to write all the names.
In Vernita Green's kitchen you see that the Bride is wearing a knife holster around her leg. The camera moves away and them back on the Bride and the holster is gone. The camera moves away and then back to the Bride and the holster is back on her leg.
When the Bride fights with Vernita Green in the kitchen scene, she plunges her dagger through the table, barely missing Vernita. In the next shot, she jumps over the table, chasing Vernita back to the living room. In the 'jumping over table' shot, the handle of the dagger can clearly be seen, still sticking out of the bottom of the table. In the next shot, the living room, the Bride is holding her dagger again, without having it pulled out of the table.
During the second hospital scene, when Buck enters the room, we see the door behind him shut before he stares around the room. When the Bride is pulling him to the doorway to ask questions and slam his head, the door is open.
When The Bride and O-Ren Ishii are fighting in the courtyard in the House of Blue Leaves, The Bride suffers a serious cut to the back and falls to the ground. Even though the close shot of her wound shows heavy blood loss, when The Bride stands back up in the next wide shot, there is no evidence of blood in the snow anywhere in the area.
When the bride fights the Crazy 88s. she unmasks a young kid who gives up. she throws him into several others, who land into a pool of bloody water. After the scene where she fights with the lights off, she narrowly avoids killing the same kid. He is fully dry, and his white dress shirt is stain free. She then chops his sword into pieces, he gives up and she spanks him.
When "The Bride" travels to Okinawa, she finds Honzo behind the bar in a small restaurant. At one point, aggravated at his employees slowness with regards to following his kitchen orders, Honzo takes a large knife from behind the counter and throws it behind him, where it lands perfectly into the knife holder mounted to the wall. At this point the shot changes to one that is further away and at a slightly different elevation. Honzo then reaches behind him to grasp for another knife out of that same rack, but the knife he had just thrown, however, is now lodged at a much different angle than it was just moments before.
In the anime sequence as eleven year old O-Ren sits on top of Matsumoto, he is wearing underwear. However, when the guards rush in and shoot at her and she uses Matsumoto's body as a shield, he is completely nude.
When The Bride enters the restaurant, she only has a T-Shirt on. When they enter the attic in the scene directly after, she suddenly has a jacket on. Also, Hattori is suddenly missing his headband when entering the attic.
The scene in the end of the film in which Budd says "That woman deserves her revenge" is mirror inverted to that exact same scene in Kill Bill: Vol. 2 (2004). In Vol. 1 his face is on the left side of the screen whereas in Vol. 2 it's on the right.
During the animated sequence in which Oren is shooting the foot off the blue-suited henchmen, the scene in which the foot is shot depicts a red suit, identical in color to the henchman who was previously shot.
At The House of Blue Leaves, when O-Ren suspects someone outside her private room, she throws a dart that sticks in a beam narrowly missing The Bride. When Go-Go goes to check things out, the dart is sticking in the beam in a downward angle when in the previous shot it was straight on. Also, considering O-Ren was seated and that the dart flew by the Bride at eye level, it would have been more conceivable for the dart to hit the beam at an upward angle, not downward.
After the kitchen fight Vernita Green fires a round at Bride over her left shoulder punching a hole in the wall between the door and the cabinet. After Bride throws her knife and Green slides down the cabinet to her demise the next shot shows Bride standing in the same spot without the bullet hole in the wall.
The Bride was shot in a chapel in El Paso, Texas. The radio music is from a fictional radio station in Wichita Falls, Texas. Since the two towns are separated by a distance of around 500 miles, it is unlikely that the radio could pick up a Wichita Falls station, unless it were at night, and the station was a high power AM station. Daytime (when the scene takes place) reception would be nearly impossible.
The airplane the Bride is flying into Tokyo is a Boeing 747, an airplane with 4 engines. However the shot of the cockpit is from an airplane with only 2 engines. There are only 2 power levers on the throttle quadrant, and the instruments only show data for 2 engines.
The details of Bill shooting The Bride are very detailed: hammer hitting primer, powder exploding in the cartridge, bullet exiting the rifled barrel of the pistol. But the bullet isn't spinning as one would do when exiting a rifled barrel.
When the Bride boards the airplane she has the samurai sword with her in the cabin. Obviously, this wouldn't happen in reality. This is a stylistic choice for this film. The couple sitting directly behind The Bride have a sword as well, and a third sword can be seen.
When The Bride is questioning Buck, her lips appear to have lipstick on them. It is possible that Buck put the lipstick on her due to the fact he was 'selling' her to his customers and wanted to keep her looking good.
Elle Driver uses her mobile phone while standing next to The Bride's life-support machine. Mobile phones interfere with hospital equipment. - Cell phones disrupt some hospital equipment, but not all. More likely it would affect the readings of a heart monitor than a "life-support machine". A conversation of a few seconds might have no effect on the machine whatsoever. In any case, Elle would not have been concerned about this.
The bride spends 13 hours in Buck's car in the hospital parking garage. After the vanishing of a 4 year coma patient and the brutal murder of two people in a hospital, the garage and a victim's car are very likely to be subject of the authorities' interest and investigation within this period of time.
At The House of Blue Leaves, when O'Ren sticks her dagger into the banister just before the Crazy 88 arrive, you can see that the banister is actually two separate pieces of wood, allowing for easy insertion of the blade.
When Hatori Honzo writes "Bill" on the fogged window and The Bride erases it shortly after, you can see fogged-over smudged wipe marks as well as part of the letter 'B' where the scene had been done over numerous times.
During the fight scene between the Bride and Vernita Green when Vernita tries to impale the kitchen knife into the Bride on the dining table, you can see the rubber blade roll upwards as it strikes the tabletop.
When O-Ren slings blood off of her blade after beheading Boss Tanaka, the blood splatters on a Yakuza boss to O-Ren's right. The very next slide shows no sign of this blood splatter on the Yakuza boss.
When O-Ren beheads Boss Tanaka, she stands on the table and gives her speech in English. All this time, her hands are empty and moving with her words. Without bending down, she suddenly has Boss Tanaka's head in her hand when saying "Just like this f-cker here!"
Near the end of the film, The Bride lifts Sofie Fatale from the trunk of a car and throws her down a snow-covered hill in front of Tokyo General Hospital's emergency entrance. During the fall, we can clearly see that Sofie is missing only one arm, her left, and that her right arm and hand are intact and appear to be in a black glove. However a bit later in the film (but earlier chronologically), in the "trunk interrogation" scene, The Bride warns that she will cut off parts of Sofie's body if she refuses to answer questions. The Bride yells, "Give me your other arm!". We only hear this (and Sofie's cries) in the US cut, but in the Japanese cut we see The Bride actually cut off Sophie's right arm at the forearm.
When The Bride kills Miki after lifting him up in the air with the sword pieced through his stomach, she throws him into the pool. In the top angle shot in which he is thrown into the pool, there is not a single drop of blood on his shirt.
When the Bride has Sophie in the trunk of her car (a blue Nissan 300zx), the shape of the trunk is inconsistent. The 300zx is a coupe with a flat trunk perimeter. In one of the scenes, we can see the front of the trunk protrude down like that of a sedan. The trunk is not the shape of the car Sophie is supposed to be in.
The many continuity lapses and other apparent technical errors are a matter of deliberate stylistic choice in this pastiche of 1970s "B" action movies. [Specifically: - When Vernita Green attempts to shoot The Bride and discharges the firearm in the cereal box at her, the bullet makes a hole in the wall behind her to her left, in the adjacent room. In the next shot after the Bride has thrown her knife, the hole in the wall is to the Bride's right. - When Hatori Hanzo throw his knife to the magnetic knife holder behind him, it ends up pointing to the ceiling. But in subsequent shots it is pointing left or right. - When the Bride is walking in the airport in Tokyo, just before her fight with O-Ren Ishii, her hair is short, about shoulder length, but in all the following scenes it is obviously a different hair style and longer. - In the "Origin of O-Ren Ishii" sequence, after she (O-Ren Ishii) kills Matsumoto and one of the bodyguards, as she shoots the other guard, the color of his suit changes from blue, to brown, and back to blue again. - In the House of Blue Leaves, just before the Bride fights Gogo, the Bride kills members of the Crazy 88 gang; however, when she is then confronted by the entire Crazy 88 gang after her fight with Gogo, the same actors/actresses in the previous fight are used again. - When O-Ren throws a dart at the bride it makes a hole in the door, but when she lowers herself down again, it is gone. - When Vernita Green is getting the towel to hand to The Bride, the towel jumps from one hand to the other between shots. - When Elle Driver changed into her nurse's outfit and prepares the fatal shot for the Bride, she removes the needle cover and places the syringe on a napkin on a tray. When she enters the Bride's room, however, she again uncaps the syringe before inserting it into her IV.]
