The Kuleshov effect is a film editing (montage) effect demonstrated by Soviet film-maker Lev Kuleshov in the 1910s and 1920s. It is a mental phenomenon by which viewers derive more meaning from the interaction of two sequential shots than from a single shot in isolation. Kuleshov edited a short film in which a shot of the expressionless face of Tsarist matinee idol Ivan Mosjoukine was alternated with various other shots (a plate of soup, a girl in a coffin, a woman on a divan). The film was shown to an audience who believed that the expression on Mosjoukine’s face was different each time he appeared, depending on whether he was “looking at” the plate of soup, the girl in the coffin, or the woman on the divan, showing an expression of hunger, grief or desire, respectively. The footage of Mosjoukine was actually the same shot each time. This shows how the editing and the sequence of a shot can have such a big impact on the overall effectiveness of the sequence, and how the order of montage can change the meaning of a piece and create a completely different tone in how the film is shot. The implication is that viewers brought their own emotional reactions to this sequence of images, and then moreover attributed those reactions to the actor, investing his impassive face with their own feelings. Kuleshov believed this, along with montage, had to be the basis of cinema as an independent art form.
