Wikipedia: "F for Fake (French: Vérités et Mensonges) is the last major film completed by Orson Welles. Initially released in 1974, it focuses on Elmyr de Hory's recounting of his career as a professional art forger; de Hory's story serves as the backdrop for a fast-paced, meandering investigation of the natures of authorship and authenticity, as well as the basis of the value of art. Far from serving as a traditional documentary on Elmyr de Hory, the film also incorporates Welles's companion Oja Kodar, notorious "hoax-biographer" Clifford Irving, and Orson Welles himself, in an autobiographical role."
