Picnic at Hanging Rock

Peter Weir's 1975 adaptation of Joan Lindsay's equivocally "true" novel is a trip, and not just because it's a mystery with no resolution. Sure it's success was based almost entirely on people thinking the story was real, but there's also a reason it won the BAFTA and Saturn awards for it's cinematography. It's a lovely movie, even if the answer to its central mystery remains unsolved and the answer Joan Lindsay came up with involves some sort of magic portal. It's probably best that Weir left that part out.
