The trio join the previously cast Oscar Isaac (Inside Llewyn Davis) and Catherine Keener (The 40-Year-Old Virgin) in The Wire creator's six-hour project titled Show Me a Hero. Based on the nonfiction book of the same name, it follows the youngest big-city mayor in the nation (Isaac) who is thrust into the center of a racial controversy when a federal court orders him to build low-income housing units in the white neighborhoods of his town, Yonkers, N.Y. His attempts to follows orders tears the community apart and leads to his political downfall.
Ryder will play the mayor's confidante and Yonkers councilwoman who loses her seat after the housing vote but makes a comeback four years later. Molina will portray a tough talking NYPD detective-turned-councilman who comes to represent the project's opponents. Bernthal will play a Harvard lawyer who represents the NAACP when it joins the government's anti-segregation case against Yonkers.
The project marks a reunion for HBO and Molina, who is nominated for an Emmy for his work in the network's film adaptation of The Normal Heart.
Ryder most recently starred in the 2013 thriller Homefront. Bernthal most recently starred in TNT's short-lived Mob City.
