Three Minutes: A Lengthening presents a home movie shot by David Kurtz in 1938 in a Jewish town in Poland and tries to postpone its ending. The film is a haunting essay about history and memory. As long as we are watching, history is not over yet. The three minutes of footage, mostly in color, are the only moving images left of the Jewish inhabitants of Nasielsk before the Holocaust. Those precious minutes are examined moment by moment to unravel the human stories hidden in the celluloid. Different voices enhance the images: Glenn Kurtz, grandson of David Kurtz, and Maurice Chandler, who appears in the footage as a young boy. Actress Helena Bonham Carter narrates the film.
