Gangster Squad (film)

Gangster Squad is a 2013 American crime action-thriller film directed by Ruben Fleischer and written by Will Beall, loosely based on a non-fiction book by Paul Lieberman. The film stars Josh Brolin, Ryan Gosling, Nick Nolte, Emma Stone, Anthony Mackie, Giovanni Ribisi, Robert Patrick, Michael Peña, and Sean Penn. Set in 1949, a group of real-life LAPD officers and detectives called the Gangster Squad are assigned to bring down crime kingpin Mickey Cohen.

After the script spent several years on the Black List, production began in September 2011 around Los Angeles, lasting through December. Despite the film originally scheduled to be released in theaters on September 7, 2012, the movie theater shooting in Aurora, which occurred seven weeks prior, led Warner Bros to delay the film's theatrical release until January 11, 2013, allowing the production team to perform re-shoots to overwrite the old sequence from which the gangsters open fire at the Grauman's Chinese Theatre.

Gangster Squad received mixed reviews from critics and grossed $105 million worldwide.
