W.A.S.T.E.

Newman Xeno's W.A.S.T.E. (yet another playfull acronym demanded by the genre) is a reference to Thomas Pynchon's post-modern classic The Crying of Lot 49. In the novel, the protagonist Oedipa Maas discovers an ancient conspiracy involving two rival mail delivery companies: Thurn and Taxis and Tristero. In the novel, Oedipa finds the recurrent acronym W.A.S.T.E. (We Await Silent Tristero's Empire) in a series of forays into the subcultures of 1960's California.
Not unlike Casanova, The Crying of Lot 49 is an excellent example of the literary pastiche which Wikipedia (with help from the OED) defines as something:

"cobbled together in imitation of several original works. As the Oxford English Dictionary puts it, a pastiche in this sense is "a medley of various ingredients; a hotchpotch, farrago, jumble." This meaning accords with etymology: pastiche is the French version of greco-Roman dish pasticcio, which designated a kind of pie made of many different ingredients."

Also:

"the term [may denote] a literary technique employing a generally light-hearted tongue-in-cheek imitation of another's style; although jocular, it is usually respectful."

Specifically pertinent to Casanova's cinematic fixation is the site's argument that:

"Pastiche can also be a cinematic device wherein the creator of the film pays homage to another filmmaker's style and use of cinematography, including camera angles, lighting, and mise en scène. A film's writer may also offer a pastiche based on the works of other writers (this is especially evident in historical films and documentaries but can be found in non-fiction drama, comedy and horror films as well)."
