NAPOLEON - Per major media reports in Spring 2016, Cary Fukunaga (HBO's True Detective series) is in talks to helm a mini-series based on Kubrick's development/research that started in the late 1960's and continued into the 1970's, bending into Kubrick's acclaimed 18th Century period piece "Barry Lyndon". Steven Spielberg to produce. Per stories in Spring 2013, Steven Spielberg was developing Kubrick's vast research & development. Please see SK News for more related media stories. Related: Taschen's release of a HUGE book on the topic! Update early 2018 - Rumors that a very popular cable-TV channel will host a Kubrick's "Napoleon" miniseries produced by Spielberg.
THE ARYAN PAPERS - There were reports circa 2010 that this former SK project (period piece set against the WWII and Holocaust Era in Nazi Germany, based on the book Wartime Lies) may be in development with a major film industry director. Aryan Papers was almost fully produced by SK in the early 1990's after thorough development - completed script, primary casting, scouted locations, wardrobe fitted, and test reels shot. According to sources, SK may have put off AP due to the wide success of Steven Spielberg's Schindler's List, and/or SK may have become too depressed to actually shoot the film after intense research on the 1940's War/Holocaust which claimed the lives of millions of people including over 6 million Jews (Kubrick was Jewish by birth).
