The movie's about Mickey 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.

Ruben Fleischer is directing and Dan Lin and Kevin McCormick are producing the movie, which is based on a series of articles by Paul Lieberman. "L.A. Rex" author Will Beall wrote the script.

Deadline first reported the news.
