On Thursday, minutes after news broke that Disney entertainment chief Peter Rice had been abruptly and unceremoniously fired, setting off an earthquake across Hollywood and igniting rampant speculation about the mysterious and irregular circumstances of his ouster, Disney C.E.O. Bob Chapek summoned Rice’s direct reports onto a phone call. When the headlines first hit the wire, most Disney executives had no idea what had just happened, or why. Many of them had been in meetings with Chapek and Rice in recent days, and had no reason to believe that anything was amiss. And indeed, as they would later learn, even Rice was shocked when he was invited to Chapek’s office earlier this week and told, in a meeting that lasted less than ten minutes, that he was being forced out of a company that some believed he might one day run.
