In the technical aspect of film performance, in fact, digital technology has replaced homologous imaging technology, and feature films constructed by computer-produced images have emerged  Computer-produced images are no longer limited to simple special effects, they make up all the montage in the film, and the main characters are all or partly computer-produced 
During the release and projection of the film, the textured film rolls, the noisy sound of the projector, or the image editing table, as well as the metal boxes that flow between cinemas, are disappearing from our sight one by one and become a thing of the past
Digital technology has subverted the whole process of film production and distribution in the past.
