It’s being reported that Sean Penn, Josh Brolin, and Ryan Gosling have all entered into negotiations to star in Warner Brothers’ upcoming crime drama, Gangster Squad.

Penn would play Mickey Cohen, a former boxer who became a top mobster in 1930s-1940s Los Angeles. Gosling and Brolin would play two police officers out to find and stop Cohen after a string on innocent people are harmed and killed by the hands of the mobster.
