The article aims at justification and description of transcendence from the object-oriented and conceptual-oriented theorizing in cinema studies resulting in the existing fragmentary theory of the cinema to the special methodological development as a framework of problematization of the existing knowledge-modified representations, for their de-objectivation, rationing and arranging according to the program of the cinema onthology, understood as a main constructive element of the cinema considered as system-of-activities. The author analyzes "turn" from classic to specific methodological work connected with transition from an activity problematization to problematization of object representations concerning cinema, replacement of a reflexive stage - process of a de-objectivation of problematization, and a stage of promotion of methodical provisions - rationing the de-objectivation knowledge. As one of initial conditions of the special methodological activity developed in article the notion of norm is defined in work of the methodologist of cinema ,connected with the fact, that the objectified parts of knowledge of a cinema received by it, have to be in relation to ontology of cinema to the scalable derivative expressed in the logical, structural and conceptual key set by theoretical model of ontology cinema. This condition does the received constructions within the described methodological work functionally jointed with each other without carrying out additional methodological work. Thus, methodology of cinema described in article as a specific form of activity, first, is the effective tool for work with any sort as object representations of a cinema, and, secondly, the subjert independent mechanism forming the objectified film theory. That ushers in essentially new stage in development of cinema studies. Summing up, personality of the new specific subject of cinema studies, that is the methodologist of cinema, intended to carry out this methodological work, is described. The functions of the methodologist in its framework are limited not only by its own strict norms, but also by a number of the ethical principles allowing it, being in an activity cinema system, to abstract from the situation and prevent from becoming a part of the system.
