<P> Film theory is a set of scholarly approaches within the academic discipline of cinema studies that questions the essentialism of cinema and provides conceptual frameworks for understanding film's relationship to reality, the other arts, individual viewers, and society at large . Film theory is not to be confused with general film criticism, or film history, though these three disciplines interrelate . </P> <P> Although film theory originated from linguistics and literary theory it also overlaps with the philosophy of film . </P> <P> French philosopher Henri Bergson's Matter and Memory (1896) has been cited as anticipating the development of film theory during the birth of cinema . Bergson commented on the need for new ways of thinking about movement, and coined the terms "the movement - image" and "the time - image". However, in his 1906 essay L'illusion cinématographique (in L'évolution créatrice; English: The cinematic illusion in Creative Evolution), he rejects film as an exemplification of what he had in mind . Nonetheless, decades later, in Cinéma I and Cinema II (1983--1985), the philosopher Gilles Deleuze took Matter and Memory as the basis of his philosophy of film and revisited Bergson's concepts, combining them with the semiotics of Charles Sanders Peirce . </P> <P> Early film theory arose in the silent era and was mostly concerned with defining the crucial elements of the medium . It largely evolved from the works of directors like Germaine Dulac, Louis Delluc, Jean Epstein, Sergei Eisenstein, Lev Kuleshov, and Dziga Vertov and film theorists like Rudolf Arnheim, Béla Balázs and Siegfried Kracauer . These individuals emphasized how film differed from reality and how it might be considered a valid art form . In the years after World War II, the French film critic and theorist André Bazin reacted against this approach to the cinema, arguing that film's essence lay in its ability to mechanically reproduce reality, not in its difference from reality . </P>
