David Hemmings (Blow-up) stars in this incredibly creepy thriller as an author (and reformed addict) who attempts to investigate the recent murder of his elderly aunt. Unfortunately, given his past, no one is interested in his theories â except, of course, the killer. Directed by Richard C. Sarafian (Vanishing Point) from a script by Academy Award® winner Paul Dehn (1951, Best Writing, Seven Days to Noon), this smart, twist-filled mystery will keep you guessing till the very end. The distinguished international cast includes Gayle Hunnicutt, Wilfrid Hyde-White, Flora Robson, Adolfo Celi, Roland Culver, Daniel Massey, Mona Washbourne and Arthur Lowe; it was photographed by Academy Award® winner Oswald Morris (1971, Best Cinematography, Fiddler on the Roof) and scored by famed jazzman Johnny Harris. Newly remastered.
