The tune that Elle Driver is whistling in the hospital is the theme from the movie 'Twisted Nerve' (1968)

The Japanese version of "Kill Bill" is longer and contains even more violence and gore.

Anybody else catch the "square" thing? Uma Thurman did the same thing in Pulp Fiction.

According to Tarantino, Sonny Chiba's character, Hattori Hanzo, is meant to be the most recent descendant of his character(s) from the TV series "Hattori Hanzo: Kage no Gundan" (or "Shadow Warriors", as it's known in the US). The series was done in multiple various installments, and in each installment, Chiba would play the next Hanzo descendant.

The siren you hear when Beatrix's face turns red after seeing her enemies is taken from the movie "Five Fingers of Death" the first kung fu movie available in the US. This is the first of two references made toward martial arts actor Lo Leigh. His name is in the rip portion of the credits.

The whole idea where The Bride (wearing Bruce Lee's yellow track suit) fights a whole gang of Japanese is an homage to Bruce Lee's movie "Fist of Fury/The Chinese Connection."

Shooting through the cereal is a reference to the episode of the Simpsons called "Simpsoncalifragilisticexpiala-D'oh-cious," which features an episode of Itchy and Scratchy called Resevoir Cats (a parody of Resevoir Dogs), guest directed by Quentin Tarantino. In the cartoon, Tarantino turns up and says something like, "What I'm trying to say with this cartoon is that violence is everywhere. It's, like, even in our breakfast cereal, man."

The scene where Go-Go stabs a man in the crotch and asks him if he still wants to "penetrate her" is a homage to Chiaki Kuriyama's infamous scene in another Japanese movie, Battle Royale.

The cereal box Vivica A. Fox shoots out of is "Kaabooom" cereal. A little foreshadowing, no?

The masks that O-Ren's hench men/woman wear are a tribute to the green hornet series, which starred Bruce Lee as a mask wearing martial arts hero.

The real name of Uma Thurman's character (The Bride) is Beatrix according to Vernita Green. It can be surmised that her name is "bleeped out" in respect to nameless hero movies like Clint Eastwood's "Man With No Name" westerns or Robert Rodriguez's El Mariachi movies. The main characters all have nicknames, like The Bride, but their real names are never known.

The Pussy Wagon is actually Quentin Tarantino's car. It was originally destined to be blown up in one of the two chapters cut from Kill Bill: Volume 2, but ultimately Tarantino decided that he was too attached to it.

During the showdown in the snow covered garden, we hear repeated plonking. This is produced by a shishiodoshi (deer frightener), a device supposedly invented by a compassionate Buddhist monk to keep deer from eating temple gardens without harming the deer.

The church scene was shot in the Mojave Desert outside of Lancaster, CA. Keep an eye out during this scene for a cameo by Samuel L. Jackson (Jules in Pulp Fiction, another Tarantino movie) as a dead organ player and actor/director Bo Svenson as the preacher.

All of the members of the Deadly Viper Assassination Squad are named after snakes, however Elle Driver's codename, California Mountain Snake, is the only non-venomous snake of the bunch. This is perhaps a cute Tarantino-esque reason for her inability to poison Black Mamba in her sleep.

When The Bride stands over the remains of the Crazy 88 Killers, Quentin Tarantino, in a mask, is among them.

The radio station that the sheriff is listening to, while driving to the murder scene, is KTRN radio in Wichita Falls, Texas. This radio station was also used in the movie The Last Picture Show. However, that radio station doesn't exist anymore in Wichita Falls.

In the opening credits it mentions the story is by "Q & U", this is Quentin Tarantino and Uma Thurman, the director and lead actress.

One of Tarantino's infamous plug-ins to his movies is The Bride walking when she arrives in Tokyo, there is an ad for Red Apple cigarettes behind her. Red Apples is the cigarette of choice in Pulp Fiction. All cigarettes in that movie are from that brand.

The vengeance music/siren shows up three times in this film: when the Bride shows up at Vernita's door, when the Bride is confronting O Ren, and when the Bride spots Sophie. Strangely, Sophie never injured the Bride during the massacre scene. This sound only shows up once in Volume 2, when the Bride spots Elle and Budd at his trailer.
