Warner Bros. have released the first trailer for their new movie, Gangster Squad which see Sean Penn, Ryan Gosling, Nick Nolte, Emma Stone and Josh Brolin all come together to unite with Zombieland director Ruben Fleischer in what looks like a fabulous new movie about Gangsters and corrupt establishment.

Check out the trailer below and let us know what you think. It looks fabulous!

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”), “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 film stars Oscar® nominees Josh Brolin (“Milk,” “True Grit”) and Ryan Gosling (“Half Nelson,” “Blue Valentine”) as the LAPD’s Sgt. John O’Mara and Jerry Wooters; Academy Award® winner Sean Penn (“Milk,” “Mystic River”) as real-life mobster Mickey Cohen; and Emma Stone as Grace Faraday, Cohen’s moll and the object of Wooters’ attention.
