Unfinished and unrealized projects
Throughout the 1980s and early 1990s, Kubrick collaborated with Brian Aldiss on expanding his short story "Supertoys Last All Summer Long" into a film. It was a futuristic fairy tale about a robot that resembles a child, and his efforts to become a 'real boy' in a manner similar to Pinocchio. Kubrick approached Steven Spielberg in 1995 with the script. Kubrick reportedly held long telephone discussions with Spielberg regarding the film. Following Kubrick's sudden death in 1999, Spielberg took the notes left by Kubrick and his writers and composed a new screenplay based on an earlier 90-page story treatment by Ian Watson written under Kubrick's supervision. In association with what remained of Kubrick's production unit, he directed the film A.I. Artificial Intelligence (2001), produced by Kubrick's longtime producer (and brother-in-law) Jan Harlan. Sets, costumes, and art direction were based on the works of conceptual artist Chris Baker, who had also done much of his work under Kubrick's supervision.
Spielberg said he felt "inhibited to honor" Kubrick, and followed Kubrick's visual schema with as much fidelity as he could. Spielberg, who once referred to Kubrick as "the greatest master I ever served", admitted, "I felt like I was being coached by a ghost." The film contains a posthumous production credit for Kubrick at the beginning and the brief dedication "For Stanley Kubrick" at the end. John Williams's score contains many allusions to pieces heard in other Kubrick films.
Following 2001: A Space Odyssey, Kubrick planned to make a film about Napoleon. Fascinated by the French leader's life and "self-destruction", Kubrick spent a great deal of time planning the film's development and conducted about two years of research into Napoleon's life, reading several hundred books and gaining access to his personal memoirs and commentaries. He tried to see every film about Napoleon and found none of them appealing, including Abel Gance's 1927 film which is generally considered a masterpiece, but for Kubrick, was a "really terrible" movie. LoBrutto states that Napoleon was an ideal subject for Kubrick, embracing Kubrick's "passion for control, power, obsession, strategy, and the military", while Napoleon's psychological intensity and depth, logistical genius and war, sex, and the evil nature of man were all ingredients which deeply appealed to Kubrick.
Kubrick drafted a screenplay in 1961, and envisaged making a "grandiose" epic, with up to 40,000 infantry and 10,000 cavalry. He intended hiring the armed forces of an entire country to make the film, as he considered Napoleonic battles to be "so beautiful, like vast lethal ballets", with an "aesthetic brilliance that doesn't require a military mind to appreciate". He wanted them replicated as authentically as possible on screen. Kubrick sent research teams to scout for locations across Europe, and commissioned screenwriter and director Andrew Birkin to the Isle of Elba, Austerlitz, and Waterloo, taking thousands of pictures. Kubrick approached numerous stars to play leading roles, including Audrey Hepburn for Empress Josephine, a part which she could not accept due to semiretirement.
British actors David Hemmings and Ian Holm were considered for the lead role of Napoleon, before Jack Nicholson was cast. The film was well into preproduction and ready to begin filming in 1969 when MGM canceled the project. Numerous reasons have been cited for the abandonment of the project, including its projected cost, a change of ownership at MGM, and the poor reception that the 1970 Soviet film about Napoleon, Waterloo, received. In 2011, Taschen published the book Stanley Kubrick's Napoleon: The Greatest Movie Never Made, a large volume compilation of literature and source documents from Kubrick. In March 2013, Steven Spielberg, who previously collaborated with Kubrick on A.I. Artificial Intelligence and is a passionate admirer of his work, announced that he would be developing Napoleon as a TV miniseries based on Kubrick's original screenplay.
In the 1950s, Kubrick and Harris developed a sitcom starring Ernie Kovacs and a film adaption of the book I Stole $16,000,000, but nothing came of them. Tony Frewin, an assistant who worked with the director for a long period, revealed in a 2013 Atlantic article: "[Kubrick] was limitlessly interested in anything to do with Nazis and desperately wanted to make a film on the subject." Kubrick had intended to make a film about Dietrich Schulz-Köhn, a Nazi officer who used the pen name "Dr. Jazz" to write reviews of German music scenes during the Nazi era. A screenplay was never completed and Kubrick's adaptation was never initiated. The unfinished Aryan Papers, based on Louis Begley's debut novel Wartime Lies, was a factor in the abandonment of the project. Work on Aryan Papers depressed Kubrick enormously, and he eventually decided that Steven Spielberg's Schindler's List (1993) covered much of the same material.
According to biographer John Baxter, Kubrick had shown an interest in directing a pornographic film based on a satirical novel written by Terry Southern, titled Blue Movie. Baxter claims that Kubrick concluded he did not have the patience or temperament to become involved in the porn industry, and Southern stated that Kubrick was "too ultra conservative" towards sexuality to have gone ahead with it. Kubrick was unable to direct a film of Umberto Eco's Foucault's Pendulum as Eco had given his publisher instructions to never sell the film rights to any of his books after his dissatisfaction with the film version of The Name of the Rose. Also, when the film rights to Tolkien's The Lord of the Rings were sold to United Artists, the Beatles approached Kubrick to direct them in a film adaptation, but Kubrick was unwilling to produce a film based on a very popular book.
