In their seventh movie, Fred Astaire and Ginger Rogers croon, swoon and sway to a glorious George and Ira Gershwin score. It's time to Slap That Bass when Fred taps to the mechanized rhythms of a luxury liner's sparkling Art Deco engine room. The two lace up roller skates and - in a sequence requiring 150 takes - spin through Let's Call The Whole Thing Off. The title-tune finale, Oscar® nominee They Can't Take That Away From Me, They All Laughed and more great numbers spread the melodic wealth, as ballet star Petrov (Astaire) and musical revue sensation Linda (Rogers) decide to wed and publicly divorce to quash persistant secret marriage rumors. Once tied, however, perhaps they shouldn't call the whole thing off.
