When news of the CAA-ICM deal broke, I knew there was one person I needed to talk to: James Andrew Miller. Jim literally wrote the book on CAA (Powerhouse, in 2016; his new effort is a history of HBO, Tinderbox, which comes out on Nov. 16). He’s got, in my opinion, the best perspective on the agency world and its place in the larger Hollywood landscape. So yesterday and today, he and I went back and forth on what it means when the home of Tom Cruise and Brad Pitt gobbles up the house of Shonda Rhimes and Ellen DeGeneres in an all-equity deal, and what the future holds for CAA and its rivals in a quickly changing talent landscape.
