sentences:  The joint musical love comedy "Waltz of Love" (1930) was such a huge success that its producer Erich Pommer decided to continue making films with the "perfect couple" Harvey/Fritsch.Thereupon, they appeared regularly together in UFA movies like "The Three from the Filling Station" (1930), "Congress Dances" by Erik Charell (1931) or "A Blonde Dream" (1932) but Fritsch was also playing in several movies at the side of Käthe von Nagy (i.e.in Billy Wilder's script debut "Her Grace Commands", 1931 or "I by Day, You by Night", 1932).
