A critical hit at this year’s Berlinale, Michael Koch’s second feature A Piece of Sky is a sober relationship drama with a difference: It takes place in a picturesque Alpine idyll, with its sections interspersed by a folk choir that acts as an unorthodox Greek chorus. Speaking at Deadline’s Contenders International award-season event Saturday, Koch explained: “It’s a story about a couple in a remote mountain village who meet and then are put to the test due to a brain cancer that the man has. The film is about how she deals with it, how the couple deal with it, and how strong love can be.”
