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.
As has been noted,mother scene outside the trailer where Bill and Budd are talking, either the hinges on the switch or the view of Budd changes from him being shot from the right then in later reprise of the scene, the same scene is left handed. This is either deliberate or an accidental reversal of the negative during editing. The negative reversal was common in "on the cheap" '70s movies where you would apprentice editors on their first solo job. However,it happened in Star Wars Episode 5, where Admiral Viet's rank insignia appeared on his right where it should have been on the left. This is a prime example of negative reversal that some how got through post production without being corrected.
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 Edgar McGraw is in the chapel examining the aftermath of the massacre, he remarks to his father that "the name on the marriage certificate is Arlene Machiavelli". There wouldn't have been any marriage certificate as this was only the wedding rehearsal; Edgar means the name on the marriage license.
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).
The Bride always pronounces O-Ren's name incorrectly. She says Oshee-ee, distinctly pronouncing the letter "i" twice. Oshii in Japanese rhymes with the French word marquee. Each i is pronounced, but there is no stop between them.
When Elle goes to the hospital to kill the Bride, the Bride has long blonde hair. We don't know exactly how long this is after the fight at the church, and all the Bride's wounds appear to have healed, but she would have had her head shaved to treat the wound in her head from the bullet. Her hair would not have grown back so quickly.
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 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.
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.
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.
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 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.
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.
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. In Vol. 1 his face is on the left side of the screen whereas in Vol. 2 it's on the right.
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 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.
The Bride is lying on the back seat in Buck's car and on some moment she is stretching out to reach the truck door to close it. The distance she has to cover with only her upper body in order to reach an open door means she would have to take her legs off the seat. In the next shot, though, it is revealed that she did not move her legs at all.
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.
During the animated sequence in which O-Ren 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 hospital Elle Driver draws a syringe full of medication with the plan to kill The Bride. She places the syringe without a cap onto a tray. In the room as she prepares to give the injection the cap has returned, which she removes with an audible pop.
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.
When the Bride is following Sophie through the highways of Tokyo, Sophie's car is left-hand drive, and obviously driving in the fast lane with exits on the right side (as in the US). In Japan, drive is on the left-hand side of the road and steering is on the right side of the car. This is corrected when the Bride dumps Sophie off at the hospital.
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 is laying comatose in her coma in the hospital ward, we hear the sound of a fly. It is the normal sound of a common house fly. Then we see the fly land on the bride, and it is a mosquito. A mosquito has a very distinctive sound (very high pitched) and is totally different from the sound of a house fly.
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.
After the Bride kills Buck in the hospital, then steals his car keys, then is laying in his car, trying to get her limbs to move, it says 13 hours have passed until she's able to fully move.
After over 13 hours, Bucks dead body would've been discovered by hospital staff, police would've been called and discovered that his car keys were missing. They would've then looked in the parking garage for his car, therefore discovered The Bride in the back seat.
When the Bride pulls up to Sophie Fatal's car at the stop light, the bride sits up on her bike, but the engine is heard continuously being gunned. A person can not reach the throttle on a Cafe style bike sitting straight up.
Texas Ranger Earl McGraw's deputy/son tells him there are 9 people dead in the Church, before they realized the bride was alive. Later, when Beatrix is narrating O'Ren's anime sequence assassinating the man in the limo, she says O'Ren played a part in killing 9 innocent people, including her unborn daughter, but she made one big mistake, she should have killed 10! The deputy should have said that 10 people were dead, or even 11 if he had realized she was pregnant, though it appears it's his dad that notices her pregnancy.
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 is pregnant with B.B. when she is assaulted by the Deadly Vipers. After awakening from her coma she confronts Vernita Green who now is the mother of a little girl. This girl, Nikiya, is at least six years old meaning Vernita would've given birth to her before the Vipers assaulted the Bride. In fact, Nikiya herself says she is only four.
Buck enters the hospital room of the Bride when the 20 minutes are over. It is obvious he is entering rather slowly and looking downwards. Later it is revealed that the Bride is lying down right next to the door. He should have seen her the moment he was going in.
It would have been impossible for The Bride to have a katana (or any weapon for that matter) on the plane or in the airport, as international regulations forbid such weapons from being brought on board or even stowed in luggage.
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.
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.
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 The Bride kills Buck and turns to rest lying her head on his torso, you can see she uses her legs for balance and stability in order to slam the door and reposition herself, yet in the next scene as she goes to the parking garage and gets in the Pussy Wagon she acts like there's utterly no feeling or strength in her legs.
The goof items below may give away important plot points.
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 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!"
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 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.]
