Robert K. Elder made a splash a few years ago with his book "The Film That Changed My Life," a collection of interviews with directors about a single film that influenced their career. Now he's back with "The Best Film You've Never Seen," (published by the Independent Publishers Group) in which directors advocate for under-appreciated and critically maligned movies. Roger said of the book, "How necessary this book is! And how well judged and written! Some of the best films ever made, as Robert K. Elder proves, are lamentably all but unknown." Here's Elder's interview with Guillermo Del Toro, who sings the praises of "Arcane Sorceror," which Edgar Wright memorably described as "the 'Barry Lyndon' of horror films."
