The Lucky Seven(1940)

Bernd Flor, an aging, but still very attractive, actor feels most at home playing the role of the tireless Don Juan in his private life. He's already been married six times and had left all six women, although the marriages were in no way unhappy. On the contrary: he is still on very good terms with all his ex-wives; especially with his first ex-wife, Katharina. Flor also has a grown-up son by her, Lukas, who is becoming increasingly critical of his fathers behavior with every passing year.
