The iconoclast has been doing just that over the past six decades with provocative and perverse films like “Pink Flamingos,” “Hairspray,” and “Female Trouble.” Now enshrined as the king of transgressive cinema, Waters is taking on new challenges with his talents. In this episode, he breaks down the creative process behind his first novel, “Liarmouth: A Feel-Bad Romance.”   Watch and listen to more from American Masters.
