This is one of the most unusual films I have ever seen. It's an offbeat, sensitively filmed look at Weimar Germany in a sort of parallel-universe version. "Cabaret" it is not! If you ever get a chance to see it, I don't want to spoil the ending for you . . . but when you see it, you'll say to yourself, "Of course! Why didn't I foresee that coming?!?" David Bowie plays a sort of innocent ne'er-do-well discharged from the German army after World War I and drifting through existence; he can't find anything to do with himself except hire himself out as a "gigolo" for rich, proto-Eurotrash war widows in ballrooms where they "dance to forget". Bowie's father is a once-domineering tyrant who has been silenced by a stroke. Bowie tries to break the news to him that he has descended so far as to play the gigolo, a betrayal of his father's macho ideals, but Dad only sits in stony silence -- a disturbing scene. Bowie plays a poor lost soul. As Western civilization decays all around him, a sinister character stalks him and tries to gain control over him; this bloke is vaguely homosexual (only suggested), and one of his lines is a real groaner of a double-entendre: "We will have you in the end!" Marlene Dietrich is the center of romantic gravity in this story; she sadly, sweetly tells Bowie the raison d'etre of forlorn women dancing with gigolos in the ballrooms -- the only way to assuage loss and stave off despair. Then she performs the song "Just a Gigolo", bringing out all the heartbreak from its depths. The end of the film is dark and truly chilling. Go see it if you can!
