SHOWTIME is going back to the ’80s with Leonardo DiCaprio.

    The premium cable network is teaming with DiCaprio and “Ray Donovan” writer Brett Johnson for an untitled drama exploring the mafia, The Hollywood Reporter has learned. The drama traces a decade-long relationship between an unstable mafia captain and a rogue federal agent, each violating the strict codes of their respective organizations. Set in 1980s Brooklyn, the potential series examines the corrosive power the Wall Street era had on both the mafia and the FBI.

    Johnson is set to pen the script and exec-produce alongside DiCaprio and his Appian Way production president Jennifer Davisson Killoran, “Ray Donovan” producers Bryan Zuriff, Charles Pacheco, Jennifer Erwin and Dan Pearson.(SD-Agencies)
