This redundant oversight slowed down production and inhibited creativity. Although central planning was supposed to increase the film industry's productivity, production levels declined steadily through the 1930s. The industry was releasing over one-hundred features annually at the end of the NEP period, but that figure fell to seventy by 1932 and to forty-five by 1934. It never again reached triple digits during the remainder of the Stalin era. Veteran directors experienced precipitous career declines under this system of control; whereas Eisenstein was able to make four features between 1924 and 1929, he completed only one film, "Alexander Nevsky" (1938) during the entire decade of the 1930s. His planned adaptation of the Ivan Turgenev story "Bezhin Meadow" (1935–37) was halted during production in 1937 and officially banned, one of many promising film projects that fell victim to an exacting censorship system.
