 Although Soviet filmmakers in the 1920s disagreed about how exactly to view montage, Sergei Eisenstein marked a note of accord in "A Dialectic Approach to Film Form" when he noted that montage is "the nerve of cinema", and that "to determine the nature of montage is to solve the specific problem of cinema".Its influence is far reaching commercially, academically, and politically.Alfred Hitchcock cites editing (and montage indirectly) as the lynchpin of worthwhile filmmaking.
