The Soviet film industry suffered during the period after World War II. On top of dealing with the severe physical and monetary losses of the war, Stalin's regime tightened social control and censorship in order to manage the effects recent exposure to the West had on the people. The postwar period was marked by an end of almost all autonomy in the Soviet Union. The "Catalogue of Soviet Films" recorded remarkably low numbers of films being produced from 1945 to 1953, with as few as nine films produced in 1951 and a maximum of twenty-three produced in 1952. These numbers do not, however, include many of the works which are not generally considered to be "film" in an elitist sense, such as filmed versions of theatrical works and operas, feature-length event documentaries and travelogues, short films for children, and experimental stereoscopic films. But compared to the four hundred to five hundred films produced every year by Hollywood, the Soviet film industry was practically dead.
