Stefano Cassetti, who was living in France, red on a newspaper that a director was looking for a beginner, Italian mother tongue but fluent french speaking, to shoot a movie as leading actor; then he decided to go to the casting. He was "obviously" signed on. I suggest that all of you should stare at his almost unbelievable without-expression look. A real perfection! In my opinion the movie shows the natural capabilities of a young actor who proves to be completely at his ease in the complex role of a multi-identity psycho killer who's capable to commit unexplainable crimes but also to act as a nice and sensitive guy. Noteworthy also the dialogs.
