In film theory, the institutional mode of representation (IMR) is the dominant mode of film construction, which developed in the years after the turn of the century, becoming the norm by about 1914. Although virtually all films produced today are made within the IMR, it is not the only possible mode of representation. Other possibilities include the Primitive Mode of Representation, which was dominant before being replaced by the IMR; certain avant-garde films that constitute a “deconstructionist” challenge to the IMR; and various non-western modes, notably pre-war Japanese film, that were possible before the IMR became the worldwide norm.   Classical Hollywood cinema is the dominant style within the IMR, but other styles such as art house, independent, and most (current) foreign styles fall no less under the IMR.
