Of course the film it reminded me the most of was his Naked Lunch, which also happens to be streaming on Netflix Watch Instantly. They would make an interesting double feature. Both deal with alternate realities which may be induced by drugs or technology (or both), or they may be symptoms of psychosis. Both are also both interesting in how they contrast with typical representations of drugs and technology. There's always a sense of dread connected to what is supposed to be a kind of liberation through the mind alterations that both offer. And both films (in fact, most of Cronenberg's films) emphasize the tactile qualities of the body, so as much as the mind may want to escape the body, there's no running away from the goo.
