Michael Pena Joining Sean Penn, Ryan Gosling, Josh Brolin in ‘Gangster Squad’

Pena, who starred in “The Lincoln Lawyer,” joins the Warner Bros. gangster film

Michael Pena will appear in "The Gangster Squad," Ruben Fleischer's mob film, TheWrap has confirmed.

He joins Sean Penn, Ryan Gosling and Josh Brolin.

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.

It'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.

Penn is playing Cohen. Brolin and Gosling are playing police officers who go after him.

Pena is repped by CAA and Management 360.
