 The bulk of influence, beginning from the October 1917 Revolution until the late 1950s (oftentimes referred to as the Stalin era), brought a cinematic language to the fore and provided the groundwork for contemporary editing and documentary techniques, as well as providing a starting point for more advanced theories.Montage theory, in its rudimentary form, asserts that a series of connected images allows for complex ideas to be extracted from a sequence and, when strung together, constitute the entirety of a film's ideological and intellectual power.In other words, the editing of shots rather than the content of the shot alone constitutes the force of a film.
