This movie is a command by Sandoz, the famous Switzerland's laboratory, who wants something about drug effects : Pollet has the idea to make an adaptation of "Le Horla" by Guy de Maupassant. Indeed, drug equals paranoia. The Laurent Terzieff's performance is constantly remarkable - he's alone in this film - and the point of view of Pollet is dark, worrying, unstable. It's much more than a curiosity : the private hell of a man who's going crazy for no reasons, except himself. Difficult to see because it's hard to find (especially in USA I guess) but essential regarding the density of Pollet's vision.
