David Fincher made his name in Hollywood as the director of movies that pushed people’s buttons—dark thrillers like “Fight Club,” “The Game,” “Seven,” and “Gone Girl”—but his new film belongs to one of Hollywood’s most esteemed genres: stories about Hollywood. Around thirty years ago, his father, the late Jack Fincher, gave him the draft of a screenplay about Herman J. Mankiewicz, who wrote “Citizen Kane” and other classics. Fincher tells David Remnick that Mankiewicz was a key figure in film—one of that first generation of writers who invented a vibrant language for movies as they came into the sound era.  Nominated for ten Academy Awards (including a Best Director nomination for Fincher), “Mank” is the story of the writer’s conflict with Orson Welles in the making of “Citizen Kane,” and their struggle is one that has bedevilled creators and critics down the decades: Who really authors a film? Plus, the journalist and fiction writer Daniel Alarcón talks about three children’s books he’s been enjoying with his son during the pandemic.
