Jiseul

Jiseul (Korean: 지슬) is a 2012 South Korean war drama film written and directed by Jeju Island native O Muel. The film is shot in black and white with the entire cast composed of local actors speaking their natural dialect. "Jiseul" means "potato" in Jeju dialect. O said he picked it as the title of his film because "potatoes are considered a staple food in many countries, often symbolizing survival and hope." Set during the Jeju Uprising on the island in 1948, O said the film does not focus on the large-scale struggle, but on a forgotten true story about a group of villagers who hid in a cave for 60 days to escape from a military attack. They hid underground for months, cold and numb, far too close for comfort—just like the potatoes to which the title refers.
