Two-time Academy Award-nominated actress Naomi Watts has been cast as former Fox News host Gretchen Carlson in Showtime’s upcoming limited series The Loudest Voice in the Room. Based on Gabriel Sherman’s book of the same title, the series will focus on the late Roger Ailes, who will be played by Russell Crowe. Carlson, a one-time Fox & Friends co-host who later led her own daytime show The Real Story, was the first woman to sue Ailes for sexual harassment, alleging that she was fired by the network because she refused his sexual advances.
