Warner Bros. has just released the international trailer for the upcoming Gangster Squad. Inspired by Paul Lieberman's nonfiction novel, this thriller focuses on the bloody conflict that erupted on the streets of 1950's Los Angeles between mobster Mickey Cohen (Sean Penn, Mystic River) and an elite team of police detectives.
According to both the film and the book, Cohen had Los Angeles in a strangehold, using his East Coast Mafia connections - in the drug, prostitution, and racketeering fields - to gain power and influence that exceeded even that of the law. Faced with dwindling resources and massive internal corruption, Chief of Police Bill Parker (Nick Nolte, Warrior) gave maverick Sergeant John O'Mara (Josh Brolin, Men in Black III) an off-the-books task: alongside a squadron of rogue LAPD officers, O'Mara was to disrupt Cohen's criminal enterprises - by any means necessary.
