Five new character posters for director Ruben Fleischer’s (Zombieland) period crime drama Gangster Squad have landed online.  The movie is set in 1940s Los Angeles and stars Sean Penn as real-life gangster Mickey Cohen, who became the target of special task force known as the “Gangster Squad”.  The pic is undergoing a bit of a marketing reboot after being pushed from its fall release date to January in the wake of the tragic theater shootings this summer.  We saw a new trailer yesterday, and these new posters do a fine job of highlighting Fleischer’s stylish take on the period setting (reminiscent of this previously released banner).  The only issue is that they still carry the old September release date.Hit the jump to check out the posters.  The film also stars Josh Brolin, Ryan Gosling, Emma Stone, Nick Nolte, Michael Peña, Anthony Mackie, and Giovanni Ribisi. Gangster Squad opens on January 11th.Posters via IMP Awards.

Here’s the official synopsis for Gangster Squad:

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.
