German helmer Doris Doerrie is moving from the light-heartedness of this year’s Berlin fest player “The Hairdresser,” to the darker and seedier side of the city with “Glueck.”

Based on a short story by author and prominent Berlin defense attorney Ferdinand von Schirach, “Glueck” (which translates to either “Happiness” or “Luck”) revolves around a young couple — a war refugee-turned-prostitute and her homeless punk boyfriend. The pair manage to build a life together, until one of the girl’s clients suddenly dies in her flat and things get complicated.

Constantin acquired film rights to “Verbrechen” (Crime), von Schirach’s bestselling book of short stories, this year. It will produce and release the film in Germany.

Oliver Berben is producing “Glueck” for Constantin; Martin Moszkowicz, Constantin’s head of film and TV, will exec produce.

Doerrie will also pen the screenplay for the pic, which is due to shoot in Berlin and Eastern Europe in the spring once a cast has been set.
