Robert Downey Jr to star on HBO drama

Los Angeles, Aug 16 (PTI) Hollywood star Robert Downey Jr is reportedly teaming up with "True Detective" creator Nic Pizzolatto for a drama on HBO. 

Pizzolatto is on board to pen the script, while the 51-year-old "Iron Man" actor will star in the project, according to The Hollywood Reporter. 

Details about the project are being kept under wraps and it's unclear if there are any official deals as of yet.

Sources say the project may be based on Downey's long-gestating Perry Mason reboot, which rather than a Warner Bros Pictures feature is now being eyed for the small screen.

The actor's wife and producing partner, Susan Downey of Team Downey, will apparently executive produce the drama with him.

HBO declined to comment. For Downey, if the deal is struck, it would mark his return to the small screen following his role on Fox's "Ally McBeal".
