Los Angeles: Hollywood superstar Leonardo DiCaprio is heading to the small screen for a big project with Showtime.
The movie star is attached as an exec producer to an untitled 1980's drama exploring the mafia along with "Ray Donovan" writer Brett Johnson, who will exec produce and pen the series, reported Variety.
The Brooklyn-set potential series follows a decade-long relationship between an unstable mafia captain and a rogue federal agent, each violating the strict codes of their respective organisations.
The drama examines the power the Wall Street era had on the mafia and the FBI. Johnson and DiCaprio will exec produce along with Appian Way's Jennifer Davisson, Charles Pacheco, Jennifer Erwin, Dan Pearson and another "Ray Donovan" member Bryan Zuriff.
