Felix Bressart, later one of the most delightful members of the Ernst Lubitsch "stock company," plays the title character in the Austrian comedy Hirsekorn Greift Ein (Hirsekorn Does Something About It). It's a typical worm-turns affair, as a mild-mannered provincial actor ends up working as a chauffeur for a scatterbrained female novelist. Slapstick is the order of the day, except in the scenes involving heroine Charlotte Susa. Guiding the actors through their paces was Rudolf Bernauer, a stage actor-manager of vast experience. Critics in 1931 felt that Hirsekorn Greift Ein was too thin to be stretched to 90 minutes.

His subjects are a bunch of intrigants, and his only real friend was the Baroness Windegg (Olga Tschechowa), a kind-hearted, witty, and very attractive woman, who however was not much loved by the Leuchtenstein upper class.
