For the first time, Warner Bros.' Toby Emmerich, Paramount's Jim Gianopulos, Disney's Alan Horn, Universal's Donna Langley, Sony's Tom Rothman, Amazon's Jennifer Salke and Netflix's Scott Stuber gather to debate streaming service ratings, movie star value, China censorship, onscreen violence and the future of a fraught movie business.

None of the "amateurish" challengers to the Murdochs' cash-cow TV channel has the resources to compete, leaving a door open for a well-funded conglomerate (say, ViacomCBS) to roll the dice.
