Her Dark Secret

Her Dark Secret German Ihr dunkler Punkt is a 1929 German silent comedy film directed by Johannes Guter and starring Lilian Harvey, Willy Fritsch and Harry Halm. The film reuinted Harvey and Fritsch who had previously appeared together in Chaste Susanne 1926, although this time their characters become a couple at the end of the film. This provided a template for a number of popular films over the following decade such as The Three from the Filling Station.
