if direction is a look,montage is a heartbeat.To foresee is the characteristic of both : but what one seeks to foresee in space, the other seeks in time. Suppose you notice a young girl in the street who attracts you.You hesitate to follow her. A quarter of a second.How to convey this hesitation? Mise en scène will answer the question 'How shall I approach her?' But in order to render explicit the other question,'Am I going to love her?',you are forced to bestow importance on the quarter of a second during which the two questions are born.
....When montage effects surpass those of mise en scènein effacacity,the beauty of the latter is doubled,the unforseen unveiling secrets by its charm in an operation analogous to using unknown quantities in mathematics.
