Marc Guggenheim (upcoming “Arrow,” Green Lantern) is negotiating to write the script for Warner Bros.’ Perry Mason, which is a potential starring vehicle for Robert Downey Jr., says The Hollywood Reporter.

Downey also is producing with his wife and partner Susan Downey and their banner Team Downey, along with Robert Cort. Guggenheim is writing a script based off an original story by Downey and Team Downey president David Gambino.

Based on the original Erle Stanley Gardner books, Perry Mason will be set in the 1930s and feature characters such as Mason’s secretary, Della Street, private investigator Paul Drake, and Mason’s longtime courtroom nemesis, Hamilton Burger.

The books were turned into a popular TV series starring Raymond Burr that ran from 1957 to 1966.

Guggenheim was an attorney before his writing career. He has worked on such shows as “Eli Stone,” “The Practice” and “Law & Order.”
