Dance number for dance number, this may be Fred and Ginger’s finest hour. The pair rarely performed with such ebullience as in the “Pick Yourself Up” tap polka; with such virtuosity as in the “Waltz in Swing Time”; and with such tenderness as in the “Never Gonna Dance” closer. Director George Stevens keeps the story — in which gambling man Fred goes to New York seeking fortune and instead finds “a fine romance” with working girl Ginger — sailing along elegantly. Add to that Astaire crooning “The Way You Look Tonight” and a Big White Set to rule them all, and you have one of the screen’s most perfect partnerships’ highest peaks.
