Variety reports today that HBO has optioned Game Change: Obama and the Clintons, McCain and Palin, and the Race of a Lifetime, the forthcoming book on the 2008 presidential election from Mark Halperin and New York’s own John Heilemann. Screenwriter Charles Leavitt (Blood Diamond), who’ll adapt the book, tells Variety: “To me, the primary was one of the greatest title fights of the century … I think it will present itself almost like a stage play, like Frost/Nixon or The Queen,†seemingly implying that the movie might focus mostly on one particular relationship, presumably the one between Obama and Hillary. Heilemann tells us, “There’s been some confusion in some of the coverage, with the book being called a novel. It’s pure non-fiction — scrupulously, rigorously reported and fact-checked nonfiction.†[Variety]
