This document discusses the auteur theory, which holds that a director's film reflects their personal creative vision. It originated with French film critics in the 1950s who argued films should reflect a director's style. Key figures who developed it include François Truffaut, who coined the term "la politique des Auteurs" and emphasized the director's role. The theory was later adopted by directors of the French New Wave and influenced film criticism. It justifies analyzing a director's body of work and recognizing their personal stamp on films. The document provides background on the theory's origin and development and its emphasis on identifying directors as "auteurs" through their distinctive style.
