As Soviet cinema made the transition to sound and central planning in the early 1930s, it was also put under a mandate to adopt a uniform film style, commonly identified as "socialist realism". In 1932 the party leadership ordered the literary community to abandon the avant-garde practices of the 1920s and to embrace socialist realism, a literary style that, in practice, was actually close to 19th-century realism. The other arts, including cinema, were subsequently instructed to develop the aesthetic equivalent. For cinema, this meant adopting a film style that would be legible to a broad audience, thus avoiding a possible split between the avant-garde and mainstream cinema that was evident in the late 1920s. The director of Soyuzkino and chief policy officer for the film industry, Boris Shumyatsky (1886–1938), who served from 1931 to 1938, was a harsh critic of the montage aesthetic. He championed a "cinema for the millions", which would use clear, linear narration. Although American movies were no longer being imported in the 1930s, the Hollywood model of continuity editing was readily available, and it had a successful track record with Soviet movie audiences. Soviet socialist realism was built on this style, which assured tidy storytelling. Various guidelines were then added to the doctrine: positive heroes to act as role models for viewers; lessons in good citizenship for spectators to embrace; and support for reigning policy decisions of the Communist Party.
