'''''Gangster Squad''''' is a 2013 crime drama inspired by the true story of the 'unauthorized' efforts of a special task force formed by the Los Angeles Police Department in 1949 to deal with an influx of organized crime occurring in the city. The so-called "Gangster Squad" had an unusually wide latitude in their authority when dealing with mobsters, many times conducting themselves in manners outside of the law. The unit has been a constant source of fascination for both the movies and television and various fictional representations of the unit have been both the heavies and the good-guys (see ''[[Mulholland Falls]], [[L.A. Confidential]], [[Mob City]]''). Originally scheduled for release in 2012, the film underwent reshoots due to some scenes bearing an uncomfortable resemblance to the Colorado movie theater shooting that occurred in July of that year. The film, which was written by former LAPD detective Will Beall and directed by [[Ruben Fleischer]], was eventually released in January of 2013. | |||

Gangster Squad is a 2013 crime drama inspired by the true story of the 'unauthorized' efforts of a special task force formed by the Los Angeles Police Department in 1949 to deal with an influx of organized crime occurring in the city. The so-called "Gangster Squad" had an unusually wide latitude in their authority when dealing with mobsters, many times conducting themselves in manners outside of the law. The unit has been a constant source of fascination for both the movies and television and various fictional representations of the unit have been both the heavies and the good-guys (see Mulholland Falls, L.A. Confidential, Mob City). Originally scheduled for release in 2012, the film underwent reshoots due to some scenes bearing an uncomfortable resemblance to the Colorado movie theater shooting that occurred in July of that year.
