Desc: Dieter Not Unhappy: Directed by Christian Schäfer. With Christoph M. Ohrt, Leslie Malton, François Goeske, Alice Gruia. Artists, vernissages, TV interviews - Dieter, a printer and publisher with universal acclaim, is a workaholic jetting through the world. Loneliness, unrequited love, a half-empty double bed - that's where photographer Marge points her lens.
