Video: Gangster Squad trailer and poster Colin D Miller October 13, 2012 Latest News and Videos 1068 A new trailer and poster has been released for Gangster Squad. No names, no badges and no mercy, but an impressive ensemble cast featuring Josh Brolin, Sean Penn, Ryan Gosling and Emma Stone it’s hard not to be excited by this one. The official synopsis for the film is: 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. “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. Gangster Squad is due out next year.
