Tony Gilroy enlisted nine composers to give the fictional films within “Behemoth!” their own musical identities, Variety reported. Pedro Pascal plays a cellist returning to Los Angeles, with music connecting the character's present experiences and memories. Gilroy described distributing the scoring work so each film inside the story could have a distinct voice. “Behemoth!” has premiered at the New York Film Festival and is scheduled for a December 4 theatrical release.
