Watch full movie online. In the film One Night. One Life, based on the cycle Pierrot Lunaire, Arnold Schönberg’s opus 21, director Oliver Herrmann has created a surreal, at times grotesque dream world set in a modern city, through which Pierrot moves like a spirit. In each new number she passes through different scenes and levels of the world around us: such as an abattoir, a peep-show, a station or a supermarket.
