World-renowned Austrian actor-singer Leo Slezak (Walter's dad) stars in this typical Viennese operetta. Slezak is cast as cab driver Leopold Weinzierl, a hidebound traditionalist who resists all forms of progress. When his daughter's sweetheart offers to buy the Weinzierl home as a potential auto-factory site, Leopold demands that the girl break off her romance, promising her hand to another suitor. To protect his property, Leopold mortgages the place to the man he's chosen as a son-in-law. But when this man proves to be a no-good rat, it is the other boyfriend who saves the day. The now-contrite Leopold celebrates his change of heart in song, just as he's celebrated every other momentous occasion in his life. The film's musical score was penned by Robert Stolz, whose previous successes included
Two Hearts in Waltz Time (incidentally, the English-language title for Liebe in 3/4 Takt was Love in Waltz Time, indicating that Stolz knew a good thing when he saw it). ~ Hal Erickson, All Movie Guide
