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", about a director who makes Hollywood's first big-budget porn film. Baxter claims that Kubrick concluded that 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, but liked the idea. 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 based on the books, but Kubrick was unwilling to produce a film based on a very popular book. Director Peter Jackson has reported that Tolkien was against the involvement of the Beatles.
