Rudin, one of the most successful and powerful producers, with a heap of Oscars and Tonys to show for it, has long been known for his torturous treatment of an ever-churning parade of assistants. Such behavior has long been engrained — and sometimes even celebrated — in show business. (AP Photo/Kevork Djansezian, File)
