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.
Penn is in talks to play Cohen.
Brolin and Gosling are in negotiations to play police officers who go after Cohen.
The film is based on a series of articles by Paul Lieberman. "L.A. Rex" author Will Beall wrote the script.
Deadline first reported the news.
