Art forgery is the creation and sale of works of art which are falsely credited to other, usually more famous artists. Art forgery can be extremely lucrative, but modern dating and analysis techniques have made the identification of forged artwork much simpler.

F for Fake is a 1973 docudrama film co-written, directed by, and starring Orson Welles who worked on the film alongside François Reichenbach, Oja Kodar, and Gary Graver. 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 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 de Hory, the film also incorporates Welles's companion Oja Kodar, hoax biographer Clifford Irving and Orson Welles as himself. F for Fake is sometimes considered an example of a film essay.
