Salangeul chajaseo (사랑을 찾아서) (In Search of Love, or Looking For Love) is a 1929 Korean film written, directed, produced, edited by and starring Na Woon-gyu (1902-1937). The film premiered at the Choseon Theater in April 1929. More than one thousand extras from Na's hometown Hoeryong were employed in the filming of Salangeul chajaseo, making the film into a symbolic epic national exodus as a protest against the Japanese occupation of Korea. Originally entitled Crossing the Duman River (두만강을 건너서), the film was banned and censored by the Japanese occupying authorities after its first showing. Popular demand caused it to be re-released, though in a heavily edited form, and renamed In Search of Love. As with the vast majority of Korean films of this era, Salangeul chajaseo is a lost film.
