2. Picnic at Hanging Rock (1975)
Peter Weirs sombre drama of a macabre disappearance is adapted from a novel, however its author Joan Lindsey always played coy as to the validity of the events depicted in her 1967 book, neither confirming nor denying her tale and taking the secret to her grave. Research by different waves of investigators and enthusiasts throughout the years never revealed any trace of school girls having effectively met their doom one fateful afternoon at Hanging Rock, yet audiences assumption of truth continues to heighten the viewing experience with pre-conditioned expectations. In other words, everyone would rather believe it and be spooked.
