The aesthetic grounds and methods of screen adaptation of theatrical performances in the context of film and television art in the USSR in the 1970s are investigated in the article as well as the influence of film and television technologies on the theatrical genre, the peculiarities of the adaptation of stage performances to the cinematographic and television environment. Attention is also paid to the revealing the peculiarities of cinematographic art as a synthetic phenomenon and its interaction with the theatrical tradition. These issues are considered in the context of the cultural and political realities of the USSR of that period, highlighting the relationship between aesthetic searches and ideological attitudes of the era. In general, a deep and systematic understanding of the process of film adaptation of theatrical performances within the framework of Soviet cinema and television art of the 1970s is submitted in the article. Since the films of this period become a time of development of existential problems of human life. The typical life of a Soviet person recedes into the background, instead, the basis of the plot becomes the search for peace of the soul, its urges for freedom, which usually unfolds against the background of something insignificant. Unlike the adaptations of literary works, when ”current ideological content” is imposed on classical original sources, adaptations of the best plays of leading Ukrainian theaters have offered perfect art, introduced a wide audience to the achievements of stage masters. But the screen adaptation of the performance is a fixation of one staging, which, of course, is shown unchanged on movie screens. The play cannot remain as it is conceived from the very beginning, and therefore gradually it has started to transform itself according to the requirements of television. However, such transformations are not always successful either. This is the beginning of the creation of a kind of the average genre between cinema and theater, which wished for better, because the aesthetic content of such a specific genre has remained opened.
