Auteur theory holds that a director's film reflects their personal creative vision. It originated in 1950s France with critics arguing that some directors' styles were distinct enough to shine through studio interference and the filmmaking process. In the 1960s, American critic Andrew Sarris popularized auteur theory as a way to analyze films and define serious artistic works through studying respected director's films. However, auteur theory was later criticized for overlooking the collaborative nature of filmmaking.
