Like C. Th. Dreyer's `La Passion de Jeanne d'Arc' (1928), Dziga Vertov's silent movie (1929) had a major impact on cinematographic techniques. While C. Th. Dreyer's movie excels through its camera movements and focal changes of lenses, D. Vertov's film shines through its shooting angles and, most importantly, through its editing with one image shots, split screens and a beautifully flowing movement throughout the whole film, based on inside screen motions, the transitions and the links between the scenes and a splendid timing.
If its techniques didn't influence directly major filmmakers, D. Vertov was at least their predecessor. One thinks immediately of Alain Resnais and Leni Riefenstahl.
Dziga Vertov was perhaps himself inspired by Fritz Lang's Metropolis.
Regarding the content, Dziga Vertov's movie is also groundbreaking. It is not only a movie in a movie, for there is a third level: D. Vertov adds the projection of his own movie in his movie! It is also the first movie which records the birth of a human being.
Moreover, D. Vertov edited his shots with juxtapositions, like wedding/divorce scenes or the change of left/right directions inside the screen.
Michael Nyman's music underlines admirably the image flow in this astonishing movie.
This eternal masterpiece of world cinema is a must see for all movie buffs.
