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. Shooting entirely in and around Los Angeles, including in many of the actual locations featured in the story, “The 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 screenplay is by Will Beall (TV’s “Castle”), based on Paul Lieberman’s series of articles entitled “Tales From the Gangster Squad.” The film is being produced by Dan Lin (“Sherlock Holmes”), Kevin McCormick (upcoming “The Lucky One”) and Michael Tadross (“Arthur”).If you haven’t seen Gangster Squad trailer, check it out now!
