Better known as One Summer of Happiness, Hon Dansade en Sommar was the most popular and financially successful of Swedish director Arne Mattson's romantic films. Based on the novel by Per Olof Ekstrom, the story revolves around the romance between college graduate Goran (Folke Sundquist) and farmer's daughter Kerstin (Ulla Jacobsson). Their plans to marry are stymied by the opposition of a local clergyman (John Elfstrom). Only after a devastating tragedy occurs does Goran realize the folly of allowing others to make decisions for him. Though Arne Mattson could have spent the rest of his career turning out Bergmanesque exercises like this one, he decided to switch creative gears and concentrate on Hitchcockian thrillers. ~ Hal Erickson, Rovi
