In his preface the author states: “The cinema is now one of the main objects on which efforts should be concentrated in order to conduct the revolution in art and literature. The cinema occupies an important place in the overall development of art and literature. As such it is a powerful ideological weapon for the revolution and construction. Therefore, concentrating efforts on the cinema, making breakthroughs and following up success in all areas of art and literature is the basic principle that we must adhere to in revolutionizing art and literature.” Kim Jong Il (1942- ) is leader of North Korea (1994- ). Kim Jong Il succeeded his father, Kim Il Sung, who had ruled North Korea since 1948.
