A confluence of near-misses and eerie coincidences transforms the past into a prophetic conspiracy in Four Flies on Grey Velvet, the final entry in Argento’s “Animal” trilogy of giallo thrillers. Directorial doppelgänger Michael Brandon plays the troubled lead, a prog-rock drummer who is blackmailed by a menacing masked figure for a murder that he may or may not have committed, and enlists the help of a detective (Jean-Pierre Marielle) to identify his blackmailer before it’s too late. Four Flies’s nightmarish set pieces rank among the director’s best, and the movie’s playfully convoluted mystery plot looks forward to Deep Red’s gleeful synthesis of Hitchcockian sadism and Antonioni-inspired alienation. 4K digital restoration by Cineteca di Bologna in collaboration with Surf Film.
