What is Time? In the monograph "Time in the Cinema" by N.E. Marievskaya this question sounds somewhat different: "How is the time of the film built?" The answer to it can be obtained right now, when all the necessary prerequisites have been created for the creation of the theory of artistic time. The author sees them primarily in the emergence of a language with which science can talk about time, about the concept of "becoming" developed by natural science. The theoretical efforts made by the author of the study are aimed at forming the dynamic poetics of the film, which implies an awareness of the process of creating a film as a movement from an idea to its final editing form. The monograph will be of interest to both theorists and practitioners of cinema and a wider range of interested readers.
