F For Fake (O. Welles, 1975)

F For Fake 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. Loosely a documentary, the film operates in several different genres and has been described as a kind of film essay. 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 as himself.
