Naked Lunch (1991)

David Cronenberg spins this surreal tale beginning in the real and stable world of a modest and honest exterminator. When the powder he uses is discovered to have narcotic qualities, we slip into a drug induced world of spying, literature, sordid sex and murder.

It's hard to measure what a viewer can gather from such a unique film. Certainly, layers of humanity are exposed when drugs are involved, but at a rather high cost. The acting is compelling and you can sense that everything has a hint of reality.
