In 1967, the Australian author Joan Lindsay released her deeply mysterious novel, “Picnic At Hanging Rock”. In 1975 the story was turned into a film directed by Peter Weir, and it went on to win many awards, including a BAFTA. The film is now regarded as one of the most iconic pieces of Australian cinema ever created. It manages to draw viewers in with its enigmatic plot: Students living at a prestigious girls’ boarding school in rural Australia visit the rock formation on Valentine’s Day, 1900. Several of the girls and a teacher disappear amongst the silent and creepy stones. They are never seen again.
