Naked Lunch by Cronenberg
This movie is based on the weird book of William S. Burroughs. Our hero, William Lee(alterego for Burroughs) goes to InterZone, after being addicted to the bug killer yellow powder substance, and killing his wife. The place he is now looks like Morocco. He believed to be a secret agent and had to write some reports on the bug shaped typewriter who talks to him. This movie is a weird hallucination, where we should decide which is true and which is only in his mind. It is a weird travel through addiction with a slowly developing story. It is quite a cult movie, so a must have
