I very comprehensively studied Irving Thalberg and his biographies. He's who [Scott]Fitzgerald roughly modeled the character after. He worked for him, as a writer, when he was at MGM. And, of course, I revisited the novel and the politics of MGM and the studio system at the time and familiarized myself with the world. There was a great deal of physical and literary work that went into it.
