EXCLUSIVE– Italian producer Domenico Procacci is going out on a limb with “Diaz — Don’t Clean Up This Blood,” a hot-button pic about the infamous police brutality against anti-globalization protesters at the 2001 G8 summit in Genoa, Italy.

The title refers to a phrase written on the wall of the Diaz School in Genoa after a police raid in which dozens of activists were hurt.

The Diaz incident was described during the subsequent trial by one of the police officers as “a butcher’s shop” and is considered the darkest page in the history of Italy’s police force.

Dozens of officers, many of them senior commanders, were accused of brutality and organizing a cover-up.

Daniele Vicari (“The Past Is a Foreign Land”) will direct the multi-language $10 million pic, with shooting due to start in Bucharest and Genoa in June.

It’s co-produced by Procacci’s Fandango and Gaul’s Le Pacte and Romania’s Mandragora Prods.

The ensemble cast includes German Jennifer Ulrich; Italians Elio Germano, Claudio Santamaria and Pippo Delbono; Romania’s Monica Barladeanu; the U.K.’s Pietro Ragusa and Gaul’s Emilie de Preissac.

“We want to depict what happened that night to try to understand it so that we can avoid that something like that could ever happen again,” Procacci said.

In a spirit of fairness, a copy of the screenplay has been sent to Italian police authorities.

Procacci lamented that due to the current climate in Italy’s Silvio Berlusconi era “nobody wants to get near this movie.” He will put up 60% of the financing and distribute it himself in Italy.
