However, between World War I and the Russian Revolution, the Russian film industry and the infrastructure needed to support it (e.g., electrical power) had deteriorated to the point of unworkability. The majority of cinemas had been in the corridor between Moscow and Saint Petersburg, and most were out of commission. Additionally, many of the performers, producers, directors and other artists of pre-Soviet Russia had fled the country or were moving ahead of Red Army forces as they pushed further and further south into what remained of the Russian Empire. Furthermore, the new government did not have the funds to spare for an extensive reworking of the system of filmmaking. Thus, they initially opted for project approval and censorship guidelines while leaving what remained of the industry in private hands. As this amounted mostly to cinema houses, the first Soviet films consisted of recycled films of the Russian Empire and its imports, to the extent that these were not determined to be offensive to the new Soviet ideology. Ironically, the first new film released in Soviet Russia did not exactly fit this mold: this was "Father Sergius", a religious film completed during the last weeks of the Russian Empire but not yet exhibited. It appeared on Soviet screens in 1918.
