The majority of production focused on melodrama and thrillers. From 1937 till 1947 because of the world economic conditions and then the involvement in World War Two, the motion picture industry in himeland did not produce a single film, but the flow of foreign film to Iran did not stop. In 1947, Esmail Koushan, with the help of some of his colleagues, established Mitra Films (1997), the first real film company in Tehran.
