Picnic at Hanging Rock

Saturday, 9.30pm, Talking Pictures TV

“A dream within a dream.” From the sun-dappled imagery and woozy pan pipe soundtrack to its spurious claim to being factbased, Peter Weir’s 1975 Australian drama is a beguiling, intoxicating experience. On Valentine’s Day in 1900, three boarding-school girls and a teacher vanish at a beauty spot in rural Victoria. The mystery of this elemental place bewitches and frustrates those left behind, with the fallout for pupils and staff, particularly Rachel Roberts’s headteacher, increasingly traumatic.
