Gangster Squad is a 2013 American action crime film directed by Ruben Fleischer, written by Will Beall and starring Josh Brolin, Ryan Gosling, Nick Nolte, Emma Stone, Anthony Mackie, Giovanni Ribisi, Robert Patrick, Michael Peña and Sean Penn. Set in 1949, the plot is a fictionalized account of the LAPD officers and detectives, called the 'Gangster Squad', who attempt to keep Los Angeles safe from Mickey Cohen and his gang.
After the script spent several years on the Black List, production of the film began in September 2011 around Los Angeles, lasting through December. The film was originally set to be theatrically released September 7, 2012, but in the wake of the 2012 Aurora, Colorado shooting, the film was pushed back to a January 11, 2013 release date by Warner Bros. to accommodate re-shoots, which took place in August 2012.
Gangster Squad received mixed reviews from critics, who praised the cast and production values but criticized the thinly-written characters.
