André Bazin (French: [bazɛ̃]; 18 April 1918 – 11 November 1958) was a renowned and influential French film critic and film theorist. He started to write about movies in 1943 and was a co-founder of the renowned film magazine Cahiers du cinéma in 1951 alongside Jacques Doniol-Valcroze and Joseph-Marie Lo Duca.
He is notable for arguing that realism is the most important function of cinema. His call for objective reality in film, as understood through the use of deep focus as well as the lack of montage, were linked to his belief that the interpretation of an entire movie or a specific scene should be left to the spectator. This placed him in opposition to prior film theorists, such as many writing during the 1920s and 1930s, who had emphasized how the cinema could manipulate reality. Bazin insisted that movies morally should serve as personalized projects by their directors to the degree that each and every one represents a director's individual vision, which reflected his broader psychological and philosophical beliefs about culture and the arts.
