The Story of Asya Klyachina. (Un)repeatable

The book "The Story of Asya Klyachina. (Un)repeatable," compiled by film historians Stanislav Dedinsky and Natalia Ryabchikova, uses documents from the archives of the Mosfilm studio, the Russian State Film Fund, the Russian State Archive of Literature and Art, and... materials from Andrei Konchalovsky's personal archive to reveal the history of how this film came into being and why viewers only saw it two decades later. Why was Yuri Klepikova's debut script rewritten several times during the production? How did the director manage to combine the theatrical actress Iya Savvina with ordinary residents of the Volga region in one frame? What is the reason for the changing titles of the film — from "The Year of Calm Sun" to "Asya's Happiness" and "The Story of Asya Klyachina"? For which parts of the film was the most fierce battle with censorship fought? And how exactly was it perceived by audiences and critics in the 1960s, 1980s, and later?
