The movie industry was centered in France and United States because of all the advances in image effects. Movies did not have sounds and it was all based on expressions, an advantage because people that spoke different types of languages could understand it. But in those times German Expressionism or Weimar period appeared due to the influence and effects of World War I. During 1910, the German movie industry was not as good as the United States, France or Italy in consequence in 1917 the German military supreme command took control over all the major film studios and consolidated them under the name of UFA. The objective of this was to centralize all the talent and technologies in one place in order to win the war….. but sadly in that time, Germany lost. The good thing was that Germany had grown an incredible movie industry, meanwhile, other countries were totally down with it.
