O.K., the first thing that you have to know about this book is that it was first published in 1912 (in French, 1915 in English). Therefore it’s very ethnocentric and thinks that white people are the bee’s knees and everyone else is less evolved.
I’d like to adapt this book into a screenplay set in modern times, where Nana, instead of a crappy singer/actress at the Parisian Varietés, is a crappy pop star in LA. My only problem is how to update her prostitution for the modern era? Maybe she becomes a webcam girl or something. Otherwise, it could work pretty well. Zola’s prescience of Britney Spears’ marriage to Kevin Federline is quite startling. Add some elements of Madonna, Christina Aguilera, Jamie Lynn Spears, most Playboy centerfolds and several other pop stars whose names we have already forgotten, and you get Nana.
