I love to accidentally find an important writer by seeing a film. That happened with "Requiem for a Dream" direct by aranofsky and written in 1968 by Hubert Selby whose tenacity is on the Nietsche level. The film is a few years old but features some incredible acting by Ellen Burstyn and Jennifer Connelly in addition to a dialogue that should be a must for purposes of addiction recovery. Here is the link to a decent review.
