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.

This collaborative film, banned for more than a decade by French censors as an attack on French colonialism (and now available only in shortened form), is a deeply felt study of African art and the decline it underwent as a result of its contact with Western civilization. Marker’s characteristically witty and thoughtful commentary is combined with images of a stark formal beauty in this passionate outcry against the fate of an art that was once integral to communal life but became debased as it fell victim to the demands of another culture.
