“A fascinating experiment adapting TV techniques - direct recording, multiple cameras, long takes, thorough pre-rehearsal - to the cinema. The Jekyll and Hyde story transposed to a modern setting affords an excuse for an homage to Renoir's beloved actors, and Jean-Louis Barrault is extraordinary as the evil genius, prancing and twitching like some nightmarish faun on an orgy of destruction. Most of the exteriors were shot on location in the streets of Paris, and the intrusion of this creature lends them a bizarre air of menace.”
