Border Line is a 2002 drama film, and the feature film debut of Korean-Japanese film director Sang-il Lee. It observes the lives of three un-related characters, a son, a father and a mother, each of whom has a troubled family background. The film is largely a character study, structured in a style of a Robert Altman movie, showing a number of different sub-plots unfold over the course of a few days. The shooting-style adopted is often similar to that of Yasujirō Ozu.
