Bongsu: in Malaysia, this is the name given to the youngest child in the family. For the Austrian film maker Gregor Grkinic, Bongsu is his younger brother, Boris. In 2012, he accompanied him on his trip to Malaysia and Thailand, where he participated in the World Championship of Pencak Silat, an old southeast Asian martial art. What resulted was an intimate portrait: one that conveys the experience of reaching physical and mental limitations in daily training sessions in a Malayan village, as well as documents the extraordinary friendship between Boris and his master, Aziwahija bin Yeop, that stretches across cultures and continents.—Gregor Grkinic
