Rhys will take on a role most famously played by Raymond Burr in the late 1950s and 1960s, and also produce the project.

"Iron Man" star Downey, Jr. was initially attached to star as Mason when the project was initially picked up up at HBO in 2016, but the plans fell apart and the movie star has since stepped down as the lead.
