Detective, Un (1969, ITA) C-90m. ** D: Romolo Guerrieri. Starring Franco Nero, Florinda Bolkan, Adolfo Celi, Delia Boccardo, Laura Antonelli. Nero plays a Mike Hammer-style investigator, who uses his fists more than his wits to find out who murdered a kinky gigolo. Several characters complicate the proceedings, but unless you dig the period flavor, you will be bored. Based on the novel Macchie di Belletto (The Make-Up Stain) by Ludovico Dentice. Original version may run 103m. English titles: RING OF DEATH, DETECTIVE BELLI.
