Due to the Aurora, Colorado tragedy, Warner Bros. has decided to move Gangster Squad release date from September 7 to January 11, 2013. The rescheduling will allow the film outfit to accommodate reshoots of some scenes in the completed film that include a shoot-out at Grauman’s Chinese Theater. The climactic scene could be a teaser for the movie which was pulled out from circulation. An alternate murder spree scene will be shot that would not take place in a movie theater.

The film is based on L.A. mob storyline during 40s and 50s era wherein the LAPD tries to take down the East Coast mafia led by Mickey Cohen out of their turf.

Gangster Squad is directed by Ruben Fleischer written by Will Beall and starred by Ryan Gosling, Sean Penn, Josh Brolin and Emma Stone.
