Los Angeles, 1949. Ruthless, Brooklyn-born mob king Mickey Cohen (Sean Penn) runs the show in this town, reaping the ill-gotten gains from the drugs, the guns, the prostitutes and—if he has his way—every wire bet placed west of Chicago. And he does it all with the protection of not only his own paid goons, but also the police and the politicians who are under his control. It’s enough to intimidate even the bravest, street-hardened cop…except, perhaps, for the small, secret crew of LAPD outsiders led by Sgt. John O’Mara (Josh Brolin) and Jerry Wooters (Ryan Gosling), who come together to try to tear Cohen’s world apart.

Under the direction of Ruben Fleischer (“Zombieland”), “Gangster Squad” is a colorful retelling of events surrounding the LAPD’s efforts to take back their nascent city from one of the most dangerous mafia bosses of all time. The film stars Oscar® nominees Josh Brolin (“Milk,” “True Grit”) and Ryan Gosling (“Half Nelson,” “Drive”) as the LAPD’s Sgt. John O’Mara and Jerry Wooters, and Academy Award® winner Sean Penn (“Milk,” “Mystic River”) as real-life mobster Mickey Cohen. The film also stars Oscar® nominee Nick Nolte (“Warrior,” “Affliction”) as LAPD Chief “Whiskey Bill” Parker, and Emma Stone as Grace Faraday, Cohen’s moll and the object of Wooters’ attention.

The movie also stars Anthony Mackie (“The Adjustment Bureau”) as Coleman Harris, a switchblade-wielding cop who proudly patrols one of the most crime-ridden areas of the city; Giovanni Ribisi (“Avatar”) as the force’s Conwell Keeler, an electronics expert who takes as much pleasure in fixing his son’s bike as he does tinkering with experimental, military-grade equipment; Robert Patrick (“Flags of Our Fathers”) as Officer Max Kennard, a deadly cop who patrols the Olvera Street beat; Michael Peña (“Battle Los Angeles”) as Kennard’s over-eager sidekick, Navidad Ramirez; and Mireille Enos as O’Mara’s wife, Connie.
