Alfred Molina will star as the movie’s director, Robert Aldrich; Stanley Tucci steps in as studio head Jack Warner; Judy Davis plays gossip columnist Hedda Hopper; and Dominic Burgess plays actor Victor Buono.
Filming for the eight-episode series will begin this fall. The first installment of the series is expected to air in 2017.
