Sometimes a film makes history; it doesn’t just document it. So it is with Granito: How to Nail A Dictator. Part political thriller, part memoir, Granito transports us back in time through a riveting, haunting tale of genocide and returns to the present with a cast of characters joined by destiny and the quest to bring a malevolent dictator to justice, each adding their “granito,” or tiny grain of sand, to the epic tale.
