Leonardo DiCaprio has been producing several exciting projects recently. Now comes word that the actor/filmmaker will be teaming up with Ray Donovan writer Brett Johnson to develop a 1980’s-era mafia drama series for Showtime.

According to Variety, the series, set in Brooklyn, will follow “a decade-long relationship between an unstable mafia captain and a rogue federal agent, each violating the strict codes of their respective organizations. The drama examines the power the Wall Street era had on the mafia and the FBI.”

DiCaprio will produce the hour-long series via his Appian Way banner. Johnson is set to write and executive produce the show. Before his current gig on Ray Donovan, Johnson worked on the hugely successful AMC show Mad Men.

If it is picked up, the mafia drama will join other exciting Showtime programs, including Homeland and the upcoming Paul Giamatti political drama Billions, set to premiere Jan. 17.

This isn’t the only small screen project DiCaprio is working on. He also has a documentary deal with Netflix. As an actor, DiCaprio will follow his impressive Wolf of Wall Street performance by playing frontiersman Hugh Glass in the feature film western The Revenant, out in January 2016.
