Cohen Media Group continues to quietly edge into the production and distribution game, most recently by acquiring the docu “Chasing Madoff,” based on Harry Markopolos’ bestseller “No One Would Listen.”Jeff Prosserman is directing and producing; Jeff Sackman, Randy Manis and Anton Nadler exec produce. “Madoff” tells the true-life tale of Markopolos’ decade-long fight to reveal Bernard Madoff’s widely destructive Ponzi scheme. The Boston-based investigator became increasingly paranoid as he privately delved into Madoff’s doings, tipping off the Securities and Exchange Commission to no avail. Charles Cohen, a commercial real estate magnate with holdings in New York, Florida and Southern California, launched Cohen Media as lead exec producer on the Oscar-nommed “Frozen River.” Company has since wrangled five projects, including “Madoff”; French pics “My Afternoons With Margueritte” and “Outside the Law” (Oscar-nommed for foreign film); “Oranges and Sunshine” (from the producers of “The King’s Speech” and starring Hugo Weaving); and recently optioning WWII drama tome “Operation Mincemeat,” which is still in development. “I saw the opportunity to start a distinctively selective small distribution company dedicated to creating a custom marketing plan,” Cohen told Variety. “Madoff” deal was negotiated by Raquel Liberman on behalf of Dembitzer and Dembitzer and Gary Rubin on behalf of Cohen Media. Film Sales Company prexy Andrew Herwitz negotiated for the producers.
