Colin Marshall talks to So Yong Kim, director of In Between Days, winner of the 2006 Sundance Film Festival's Special Jury Prize for Independent Vision, and more recently Treeless Mountain, which is now available on DVD. The story of two very young sisters in Seoul left with their distant aunt while their mother searches for their absent father, the film belongs solidly to the realist tradition while evoking the scale, perspective and feel of childhood. The New York Times' A.O. Scott calls Treeless Mountain one of the "vital, urgent and timely" vanguard members of the new genre of "neo-neorealism."
