The geographical dead center of North America and the beloved birthplace of Guy Maddin, Winnipeg is the frosty and mysterious star of Maddin’s “docu-fantasia.” A work of memory and imagination, the film burrows into what the director calls “the heart of the heart” of the continent, conjuring a city as delightful as it is fearsome, populated by sleepwalkers and hockey aficionados. Take part in Winnipeg’s epic annual scavenger hunt! Pay your respects to the racehorses forever frozen in the river! Help judge the yearly Golden Boy pageant! What is real and what is fantasy is left up to the viewer to sort out in Maddin’s hypnotic, expertly conceived paean to that wonderful and terrifying place known as My Hometown.
