Nonagenarian artist Kim Tschang-Yeul, one of the most recognized Korean artists of his generation, has built his singular body of work around the representation of a single, fascinating motif—the water drop. This collaboration between an inscrutable artist and his filmmaker son speaks volumes, despite documenting a man of very few words, whose practice embraces meditative silence. \"He who knows, does not speak; he who speaks, does not know.\" The Man Who Paints Water Drops discovers non-verbal ways of expressing and understanding Kim's obsession with painting water drops and its origin, rooted in Korea's history. This portrait of a career and also communication—between father and son, artist and audience, artist and self—is driven by intimate access and serene skill at reducing and expanding moments and meaning. How well can we ever know the people closest to us, their dreams, ambitions and traumas, without ever voicing them, or sharing them in common? See: the water drop.
