Another director should tackle Naked Lunch
Cronenberg's film really doesn't use very much material from the novel Naked Lunch itself, only a few out of context quotes and characters. It's mostly a fictionalized account of Burroughs' life and creative process.
Cronenberg stated that a direct adaptation of the novel wouldn't work because a. there's no plot, b. the violence and pornography are too over the top, and c. it would be prohibitively expensive.
Now, I could see why a director might shy away from putting "Hassan's Rumpus Room" or "A.J.'s Annual Party" on film. However, it certainly would be feasible to adapt any number of scenes in Naked Lunch on the screen, and in so doing put together a film that gives the viewer a much better idea of the content and spirit of the novel.
As for the lack of plot, I think that the right model for such an adaptation would be Fellin's Satyricon, which in a sense used the picaresque Naked Lunch of ancient Rome as its source material.
Normally I detest remakes, but when it comes to adapting novels and plays as source material, the more attempts we have to get it right the better.
