(Der blaue Engel) Marlene Dietrich’s iconic image is born in this raucous foray into Berlin’s cabaret scene, as an uptight professor finds himself pulled in by its magnetic lure. A buttoned-up schoolteacher is driven to insanity by obsessive desire, following a chance encounter with a chanteuse at a local cabaret. Headliner Lola Lola, brought to sparkling life by Dietrich – von Sternberg’s regular on-screen collaborator – soon seduces him from his respectable world and into Berlin’s erotic subterranea. Jannings is pitiful yet sympathetic as a hapless stooge unable to resist Lola’s world, in all its glamour and filth.
