Warner Bros. has offered Emma Stone the role of Jean, a woman romantically attached to two men: the gangster Mickey Cohen and the police officer who is chasing him down, TheWrap has confirmed.

Sean Penn is playing Cohen. Ryan Gosling is playing Sgt. Jerry Wooters.

Josh Brolin and Michael Pena also star.

The movie is about Cohen, the Brooklyn-born gangster who was sent to Los Angeles by Meyer Lansky to keep an eye on Bugsy Siegel. Cohen became a mob kingpin himself in the 1940s, and at one point fired rounds from two .45-caliber handguns into the ceiling of the Hotel Roosevelt lobby.

"Gangster Squad" is based on a series of articles by Paul Lieberman. "L.A. Rex" author Will Beall wrote the script.

Ruben Fleischer is directing and Dan Lin and Kevin McCormick are producing.
