Query: Decent doc about the Great Lost American Novel

To me, this wasn't just about him tracking down Dow, but every writer who wrote their one story, then vanished, but so did the book! The doc also sparks interest in many other "lost" books. Salinger isn't around to discuss what his life was like for the past 40 years, John Kennedy Toole isn't around to discuss "Confederacy of Dunces", but Mark captured Dow on film, and even if people have their issue with the documentary, it succeeded in what Moskowitz set out to do. Just a book he remembered from childhood that he didn't get at the time, revisited it and blew him away, and began his journey into what happened.The bonuses cover what happened after the film was released.
