Fred Astaire

Context: In 1939, Astaire left RKO to freelance and pursue new film opportunities, with mixed though generally successful outcomes. Throughout this period, Astaire continued to value the input of choreographic collaborators and, unlike the 1930s when he worked almost exclusively with Hermes Pan, he tapped the talents of other choreographers in an effort to continually innovate. His first post-Ginger dance partner was the redoubtable Eleanor Powell--considered the finest female tap-dancer of her generation--in Broadway Melody of 1940, in which they performed a celebrated extended dance routine to Cole Porter's "Begin the Beguine." In his autobiography Steps in Time, Astaire remarked, "She 'put 'em down like a man,' no ricky-ticky-sissy stuff with Ellie. She really knocked out a tap dance in a class by herself."  He played alongside Bing Crosby in Holiday Inn (1942) and later Blue Skies (1946) but, in spite of the enormous financial success of both, was reportedly dissatisfied with roles where he lost the girl to Crosby. The former film is particularly remembered for his virtuoso solo dance to "Let's Say it with Firecrackers" while the latter film featured an innovative song and dance routine to a song indelibly associated with him: "Puttin' On the Ritz." Other partners during this period included Paulette Goddard in Second Chorus (1940), in which he dance-conducted the Artie Shaw orchestra.  He made two pictures with Rita Hayworth, the daughter of his former vaudeville dance idols, the Cansinos. The first, You'll Never Get Rich (1941), catapulted Hayworth to stardom and provided Astaire his third on-screen opportunity to integrate Latin American dance idioms into his style (the first being with Ginger Rogers in "The Carioca" number from Flying Down to Rio (1933) and the second, again with Rogers, was the "Dengozo" dance from The Story of Vernon and Irene Castle (1939)), taking advantage of Hayworth's professional Latin dance pedigree. His second film with Hayworth, You Were Never Lovelier (1942), was equally successful and featured a duet to Kern's "I'm Old Fashioned," which became the centerpiece of Jerome Robbins's 1983 New York City Ballet tribute to Astaire. He next appeared opposite the seventeen-year-old Joan Leslie in the wartime drama The Sky's the Limit (1943), in which he introduced Arlen and Mercer's "One for My Baby" while dancing on a bar counter in a dark and troubled routine. This film, which was choreographed by Astaire alone and achieved modest box office success, represented an important departure for Astaire from his usual charming happy-go-lucky screen persona, and confused contemporary critics.  His next partner, Lucille Bremer, was featured in two lavish vehicles, both directed by Vincente Minnelli: the fantasy Yolanda and the Thief, which featured an avant-garde surrealistic ballet, and the musical revue Ziegfeld Follies (1946), which featured a memorable teaming of Astaire with Gene Kelly to "The Babbit and the Bromide," a Gershwin song Astaire had introduced with his sister Adele back in 1927. While Follies was a hit, Yolanda bombed at the box office, and Astaire, ever insecure and believing his career was beginning to falter, surprised his audiences by announcing his retirement during the production of Blue Skies (1946), nominating "Puttin' on the Ritz" as his farewell dance.  After announcing his retirement in 1946, Astaire concentrated on his horse-racing interests and in 1947 founded the Fred Astaire Dance Studios, which he subsequently sold in 1966. CANNOTANSWER
