The 1975 Australian film Picnic at Hanging Rock unfurls an atmospheric, unsettling little story of mysterious forces disturbing the titular outing, enjoyed by students at a Victoria, Australia, girls’ school circa 1900. In the movie, director Peter Weir keeps the proceedings eerie and foreboding as some of the girls on the picnic just vanish, leaving their classmates and the school personnel baffled and devastated. A well-deserved international success, Picnic at Hanging Rock grips the viewer even as not a lot happens: the film is all mood. The emotions are strong, but nothing about it screams, “I need to be sung.”
