In this essay, the author synthesizes his views on the policy of authors (la politique des auteurs), and at the same time advocates the 'auteur' theory. The author, who draws on the views of André Bazin, Richard Roud and François Truffaut and gives an account of its complexity and of the people (connected to the Cahiers du Cinéma) involved in the theory, tries to formulate what may be regarded as the definition of 'auteur'. He states in his essay that there are three premises to 'auteur' theory: the technical competence of the director, the director's distinguishable personality and interior meaning. He says that three concentric circles can represent the three premises, of which the outer one represents technique, the middle one - individual style and the inner one - interior meaning. The director's interrelated roles can be designated as the roles of the technician, stylist (metteur en scene) and the 'auteur' respectively. In his concluding remarks, the author says that the 'auteur' theory alone is a theory model under constant evolution, and that it is unlikely to ever come into force.
