This bizarre and fascinating film essay chronicles how hundreds of silent films from the early 1900s were discovered frozen and buried in Dawson City, Yukon, dug up by a bulldozer in 1978. 350 miles south of the Arctic Circle, Dawson City became a boom town of the Klondike Gold Rush in 1898 when gold was discovered. 100,000 prospectors flocked to the area, and casinos, saloons and theatres sprang up overnight. Legendary theatre owners Sid Grauman and Alex Pantages both got their start there, as did silent film matinee idol William Desmond Taylor. Soon silent films were a popular attraction, and Dawson City was the last stop on the distribution circuit; hundreds of prints of unwanted films ended up being buried under the hockey rink and, over the decades, forgotten. This new documentary by Bill Morrison (Decasia) draws on these rare, permafrost-preserved silent films and newsreels, pairing them with archival footage, interviews, historical photographs, and an enigmatic score by Sigur Rós collaborator and composer Alex Somers to create a poetic portrait of a lost time.
