Russell Crowe has been cast as Roger Ailes in Showtime’s untitled limited series about the late chairman and CEO of Fox News, which the network confirmed it’s picked up for eight episodes. The project is based on New York Magazine reporter Gabriel Sherman’s best-selling book on Ailes, “The Loudest Voice in the Room,” which details Ailes’ own rise to power and how he built Fox News into the cable news behemoth it is today.
