Is Iron Man headed to the small screen? A new report suggests that Robert Downey Jr. is developing a new project for HBO with True Detective mastermind Nic Pizzolatto—and that Downey would star in the potential series.

According to Variety, Pizzolatto is attached to write a drama that would be a version of Downey’s long-gestating Perry Mason remake. Perry Mason, first a literary creation of Erle Stanley Gardner and then a CBS television character, is a criminal defense lawyer made iconic by actor Raymond Burr.

HBO and reps for both Downey and Pizzolatto declined to comment, so no official word yet. However, Downey (who recently brought a courtroom drama to the big screen with The Judge) has reportedly been developing a Perry Mason reboot for years, and the project has been at HBO since May.

For Pizzolatto, the project could represent a fresh start at HBO now that True Detective  seems to have fizzled out. And for Downey, who has become a box office superstar thanks to his Marvel work, the project would represent his first TV work since his Ally McBeal reprising character over a decade ago.
