"The bride is back for the final cut."
Kill Bill: Vol. 2 - Easter Eggs & Hidden Details
Easter Eggs
The Lonely Grave of Paula Schultz
The Bride is buried in a grave marked "Paula Schultz." This is widely believed to be a reference to the wife of Dr. King Schultz, the character played by Christoph Waltz in Tarantino's later film, "Django Unchained" (2012), connecting the two films within a shared universe.
Samuel L. Jackson's Cameo
Frequent Tarantino collaborator Samuel L. Jackson has a brief, uncredited cameo as Rufus, the organ player at the wedding rehearsal chapel. Though we only see him in silhouette, his voice is unmistakable.
Blade Runner Reference
When Elle Driver has her remaining eye plucked out by Beatrix, her spastic, flailing reaction on the floor is a direct visual homage to the death scene of Pris, the replicant played by Daryl Hannah herself in the sci-fi classic "Blade Runner" (1982).
The Carrucans of Kurrajong
In Esteban Vihaio's house, a book titled "The Carrucans of Kurrajong" by Jasmine Yeun can be seen. This is an inside joke, as Jasmine Yeun Carrucan was the Second Assistant Camera operator on the film.
Black Mamba vs. Sidewinder
Elle Driver uses a black mamba snake to kill Budd. The Bride's codename is Black Mamba, and Budd's is Sidewinder. This creates a symbolic death where, in a way, "Black Mamba" is responsible for the death of "Sidewinder."
