Turner Classic Movies' Greatest Classic Films Collection: Astaire & Rogerscollects four movies on two double-sided discs, with the bonus features that appeared on the single-disc versions of the movies. The Astaire-Rogers films mix light romantic comedy (usually centered around mistaken identities and ending, inevitably, in blissful wedding promises) with elegant dinner wear and surreal sets intended to transport '30s audiences away from the Depression to such locales as Rio, Paris, and Venice. The two stars are also aided by a recurring stable of RKO players such as Edward Everett Horton (master of the double-take), Eric Blore, and Helen Broderick. And then there's that sensational dancing set to great songs by the likes of Irving Berlin, George and Ira Gershwin, and Jerome Kern, numbers that are not merely entertaining but also innovative for their time in that they reveal character and advance the plot. Add it all up, and you have a recipe for an irrepressible joie de vivre that practically defines the movie musical.The Gay Divorcee(1934) is their best early picture, a loose adaptation of Astaire's stage show, 'The Gay Divorce.' The only song retained for the movie is Cole Porter's smash hit "Night and Day," which is the setting for a sublime pas de deux between Fred and Ginger. The closer is the sprawling 17-minute ensemble number "The Continental."  With a score by Irving Berlin,Top Hat(1935) is most famous for two numbers, Astaire's definitive tuxedo setting "Top Hat, White Tie, and Tails" and the feathery duet "Cheek to Cheek." But other joys include Astaire's "Fancy Free" declaration, "Isn't It a Lovely Day," and the grand finale "The Piccolino." Maybe their most enjoyable picture,Swing Time(1936) features the set-piece "Pick Yourself Up," in which Rogers "teaches" Astaire to dance before they break into a spectacular number; the farewell ode "Never Gonna Dance," and the Oscar-winning "Just the Way You Look Tonight," from the team of Jerome Kern and Dorothy Fields.Shall We Dance(1937) has a complex plot that has Astaire and Rogers actually getting married before the final credits roll, and turns George and Ira Gershwin's brilliant "They Can't Take That Away from Me" into a heartbreaking ode. Other great songs include "Slap That Bass," "They All Laughed," and "Let's Call the Whole Thing Off," unforgettably performed on roller skates. Bonus features include commentaries on the last three films, featurettes, and vintage shorts and cartoons.--David Horiuchi
