Maurizio Merli

After a decade of minor film roles, 1974 saw a breakthrough for Merli with his first starring role in a remake of romantic drama Catene, and brought in as lead in the third of a franchise for White Fang to the Rescue, in part due to his resemblance to Franco Nero.^{[citation needed]} However the following year became a true banner one for Merli when he made Violent Rome which was an enormous success, and made him the star of poliziotteschi genre. He went on to make 11 more, two as Commissario Betti, Merli's character in Violent Rome. Betti is a detective who metes out apoplectic violence, and in some way the character was an exploitative imitation of American police thrillers like Dirty Harry and a film of Nero. However, distinctive elements in Violent Rome reflected Italian law enforcement of the era. Similar to Luigi Calabresi, a real life policeman who though morally upright became notorious after being denounced in media for brutality and was assassinated, the character of Betti finds himself a marked man. At the ending of Violent Rome, Betti's now paralyzed in a wheelchair colleague cannot escape the conviction that Betti is fated to have a short future.

Merli appeared in a few international productions and even a comedy, but remained identified with Betti the toughest hero of poliziotteschi. The genre's decline as he moved into middle age meant that his last roles were in lesser productions.

The athletic looking Merli enjoyed participating in sport and was unaware of having any heart trouble, but he died suddenly in 1989 of myocardial infarction after a tennis match.
