French film fans noticed after World War 2 that directors often had consistent styles, techniques, and themes across their films. They developed the theory of "auteur theory" which considers directors who exhibit a distinctive and consistent visual or thematic style across multiple films as the authors of those films, similar to how authors are considered the authors of books. Famous directors considered auteurs include Akira Kurosawa, Michael Scorsese, Alfred Hitchcock, Stanley Kubrick, and Steven Spielberg. J.J. Abrams is also considered an auteur for his identifiable and mysterious sci-fi style seen across films like Mission Impossible 3, Star Trek, and Super 8.
