"Kuleshov's insights gave voice to a temporal recombinatory practice that is older than the film medium, evident for example in nineteenth-century programming of magiclantern exhibitions, where showmen learned to build – and to rework – stories from the slides that they happened to have. But these early practices, particularly as they appeared through film's first decade or so, actually made use of recombinatory logic in a double sense. First, in the hands of film-makers such as Edwin S. Porter and D. W. Griffith, the sequence of shots was manipulated to construct overall textual meaning (just as Kuleshov would later theorise and experimentally demonstrate). Second, the positioning of the films of Porter, Griffiths and others into full programmes (complete with lantern slides, actualités and other narratives) could itself radically transform the meanings of individual films. Here, the programmer (usually the projectionist) could, through simple manipulation of film sequence, comment upon or build different frameworks of coherence for a particular film. This metalevel of recombination was not discussed by Kuleshov and, indeed, largely took residual form in exhibition practice. But it was seized upon by television (and radio), where programmatic recombination would emerge as the economic lifeblood of the industry in the form of the rerun. And it provides one of the keys to television's distinctive deployment of ephemeral programme elements. Television's programming logics turn on a triad of organisational principles when it comes to texts, ephemeral and not: sequence, interpenetration and repetition."

 Derek Kompare (2005) offers an excellent overview of this practice.

"Montage––juxtaposing images by editing––is unique to film (and now video). During the 1920s, the pioneering Russian film directors and theorists Sergei Eisenstein and Dziga Vertov demonstrated the technical, aesthetic, and ideological potentials of montage. The 'new media' theorist Lev Manovich has pointed out how much these experiments of the 1920s underlie the aesthetics of contemporary video.
Eisenstein believed that film montage could create ideas or have an impact beyond the individual images. Two or more images edited together create a 'tertium quid' (third thing) that makes the whole greater than the sum of its individual parts.
Eisenstein's greatest demonstration of the power of montage comes in the 'Odessa Steps' sequence of his 1925 film Battleship Potemkin. On the simplest level, montage allows Eisenstein to manipulate the audience's perception of time by stretching out the crowd's flight down the steps for seven minutes, several times longer than it would take in real time"
"Technique which demonstrates the inherent power of montage as a primary tool in the manipulation of the viewer's perception. According to Kuleshov, cinema consists of fragments and it is their combination rather than their content that is essential in evoking and triggering different emotions. His original experiment consists of using the same shot of the character's face, frozen in a neutral emotion while editing it next to different objects he appears to be glancing at: a girl in a coffin, a bowl of soup, and a woman. The audience interpreted the three situations as expressions of sadness, hunger and lust."
"for over 40 years, Pablo has been putting his stamp on the moving image through works such as the opening of Stanley Kubrick's Dr. Strangelove and the revolutionary split–screen montage of 1963's The Thomas Crown Affair. He has also created the opening titles for Hal Ashby's Being There (1979) and Gus Van Sant's To Die For (1995)."
