How Tarantino uses intertexuality in Kill Bill.

Quentin Tarantino is famous for using brilliant intertexual references in all of his films.

These may vary from obvious references like naming characters after influential artists (In Inglourious Basterds, the alias name Sgt. Donny Donowitz uses is named after cult Italian director "Antonio Margheriti". Also, the surname of the character Omar Ulmer is a reference to German Expressionist filmmaker Edgar G. Ulmer) or the use of music from spaghetti westerns and 1950s noir thrillers, to very subtle references like the Calabash Meerschaum pipe, which the detective character Hans Landa smokes in Inglourious Basterds, being the exact same pipe that detective Sherlock Holmes is know to use.

Also, almost all of Tarantino's films display the copyright info in small roman numbers directly under the title of the film in the opening credits. This is an homage to many films produced in the 1960s and 70s, which Tarantino greatly admires.

Tarantino's use of the Ennio Morricone composed soundtrack in Kill Bill Vol. 2 when the bride escapes from being buried alive is a reference to the famous confrontational threeway shootout scene in "The Good, the Bad and the Ugly", a 1966 spaghetti western directed by Sergio Leone (who also directed the crime thriller Once Upon A Time In America).  The location is another homage to this scene, as the Kill Bill Vol.2 scene also takes place in a graveyard.

These intertexual references serve as an homage to Sergio Leone and the spaghetti western genre. The soundtrack and location choice also hint towards the similarity of the three main characters in both films representing the good, the bad and the ugly. 

In the1966 film, the character named Blondie is 'the good', Sentenza "Angel Eyes" is 'the bad' and the bandit Tuco is 'the ugly'.

In Kill Bill Vol.2 these three types of characters are refered to by the blonde Bride taking Blondie's place as 'the Good', Bill being 'the Bad' and Bud serving as 'the Ugly'. 

In the original 1966 film, Blondie 'the Good' ends up killing 'the Bad' and leaving 'the Ugly' in a very awkward situation.

The purpose of this reference also foreshadows the final ending of the Kill Bill story.

It gives the Bride iconic status and foreshadows that she, like Blondie, is going to win over the Bad and the Ugly, like Blondie does in the1966 western.

"The Good, the Bad and the Ugly" is also referred to in the opening scene of Kill Bill Vol.1, when the Bride "the Good" is lying on the floor when Bill "the Bad" shooting her, similar to the western scene in which Blondie "the Good" is lying on the floor near to death from dehydration when Tuco "the Ugly" points a gun at him.
