according to french film critics in the 1950s who is the single author or auteur of a film
Auteur The definition of an auteur has been debated since the 1940s. AndrÃ© Bazin and Roger Leenhardt presented the theory that it is the director that brings the film to life and uses the film to express their thoughts and feelings about the subject matter as well as a worldview as an auteur. An auteur can use lighting, camerawork, staging and editing to add to their vision.[5]
