La morte risale a ieri sera (1970)
La morte risale a ieri sera is a 1970 giallo film directed by Duccio Tessari. Written by Biagio Proietti, the film is based on the novel I milanesi ammazzano al sabato by Giorgio Scerbanenco. La morte risale a ieri sera stars Raf Vallone and Frank Wolff. The film's score was composed by Gianni Ferrio, whose baroque and psychedelic contributions to the soundtrack were described by one critic as inconsistent with the tone of the film.
