“As members of the motion-picture industry, we must face and accept an especial responsibility. Motion pictures are inescapably one of the world’s greatest forces for influencing public thought and opinion, both at home and abroad. In this fact lies solemn obligation. We refuse to permit the effort of Communist, Fascist, and other totalitarian-minded groups to pervert this powerful medium into an instrument for the dissemination of un-American ideas and beliefs. We pledge ourselves to fight, with every means at our organized command, any effort of any group or individual, to divert the loyalty of the screen from the free America that give it birth. And to dedicate our work, in the fullest possible measure, to the presentation of the American scene, its standards and its freedoms, its beliefs and its ideals, as we know them and believe in them.”

– The 1944 Statement of Principles of the Motion Picture Alliance for the Preservation of American Ideals, which disbanded in 1975.
