Detective Belli

In 1969, Italian film director Romolo Guerrieri directed "Detective Belli", a gritty crime drama starring Franco Nero as Commissioner Stefano Belli, a rough-around-the-edges investigator tasked with solving the murder of a record producer in Rome. As Belli delves deeper into the case, he's drawn into a complex web of blackmail, deception, and double-cross involving a series of suspects, including a model, pop singer, lawyer, and his beautiful wife. The film is based on the novel "Macchie di belletto" by Ludovico Dentice and was released in Italy to moderate success.
