In his first movies, Eisenstein did not use professional actors. His narratives did not focus on individual characters. Instead, they addressed broad social issues, especially class conflict. He used basic characters, and the roles were filled with untrained people from the matching classes. He avoided using stars. Eisenstein's vision of communism brought him into conflict with officials in the ruling system of Joseph Stalin. Like many Bolshevik artists, Eisenstein pictured a new society which would pay for artists totally. This would free them from bosses and budgets. It would leave them free to create. But budgets and producers were as important to the Soviet movie business as the rest of the world. The isolated, post-revolution, new nation did not have the resources to nationalize its movie business at first. When it did, limited resources — both monetary and equipment — required production controls as big as in the capitalist world.
