Willi Forst

Willi Forst, born Wilhelm Anton Frohs (7 April 1903 – 11 August 1980) was an Austrian actor, screenwriter, film director, film producer and singer. As a debonair actor he was a darling of the German-speaking film audiences, as a director, one of the most significant makers of the Viennese period musical melodramas and comedies of the 1930s known as Wiener Filme. From the mid-1930s he also recorded many records, largely of sentimental Viennese songs, for the Odeon Records label owned by Carl Lindström AG.
