Silent film narrator Seo Sang-ho, who had his heyday in the “times of motion pictures” wherein films were just “novel invention and acting photos” as distinguished from “the times of movies,” the incomparable Park Seung-pil who played the roles of theater manager, leader of a troupe, filmmaker, theater owner, and distributor simultaneously, and Lee Gu-yeong, who showed superior talents not only in movie planning and direction but also in public relations -- these are pioneers in the movie world who realized the infinite potential of movies in the early days based on Dansungsa. Their amazing moments of not only screening imported films but also adding performances and finally producing movies firsthand under restrictive conditions wherein Chosun people could not own theaters but were merely assured of the right to performance can be seen in this book, titled < Dansungsa>.？？
