Un bigote para dos (1940)
Enriqueto, the proud owner of a splendid mustache, feels his heart divided between the kindly Manolita and the feckless Lilí. (A redubbed version of the Austrian film Immortal Melodies —Unsterbliche Melodien, 1935—, an operetta based on the life of the Austrian composer Johann Strauss, the Waltz King; with a new humorous plot and new music and songs. The original soundtrack was lost around 1949; only a 2014 subtitled version is preserved.)
