According to this principle, Prado invented the "magic disc" in 1832. The "special tray" can make the picture drawn on the zigzag cardboard box move because of the movement, and can also make the generated moving picture visually decompose into various images. The appearance of "special effects CD" indicates that the invention of film has entered the stage of scientific experiment. 1834, Halner, an American, succeeded in the experiment of "Movable Video Disc".

The development of film theory is closely related to every important film creation movement. The exploration of the Soviet school, the pioneering practice of France and Germany, and the new realism of Italy inspired the establishment of montage theory, avant-garde theory and real aesthetics respectively. The French new wave movement and the French film handbook school complement each other and enjoy a world-renowned reputation.
Eisenstein's montage theory and Bazin's long shot theory have deepened our understanding of movies. The film author theory emphasizes the core role of the director and strengthens the guidance of film practice. Hollywood studio system, genre film mode and later new Hollywood independent films are all models of film industrialization.
