Sixty-five years after the Joan Crawford film version of the James M. Cain novel Mildred Pierce, Todd Haynes has made what he considers a more faithful adaptation of the melodramatic novel. To do so, he made it as an HBO mini-series, giving him five-and-a-half hours to tell the story (the first two parts air Sunday). A mini-series allows a filmmaker to do justice to a novel's textures, details, and layers that often have to be stripped out in a two-hour feature. Which made us wonder: What other great books that have previously had truncated big-screen adaptations would be better remade this way? Some ground rules: This list only includes books that have already been made into movies, exempting some works that would make a hell of a marathon, like The Confederacy of Dunces and Don DeLillo's Underworld. It also doesn't include films that had crappy movie adaptations, but which still could decently be done in two hours, like Red Badge of Courage, famously butchered by John Huston.
