You Were Never Lovelier (1942)

An American dancer (Fred Astaire), who finds himself penniless in Argentina because of gambling, reluctantly agrees to woo the daughter (Rita Hayworth) of a Buenos Aires businessman (Adolphe Menjou) then dump her in exchange for an engagement at the father's nightclub. But fate plays funny tricks. Directed by William A. Seiter (ONE TOUCH OF VENUS). This sliver of a musical benefits greatly by the chemistry between Astaire and Hayworth, who dance superbly together. The songs by Jerome Kern (music) and Johnny Mercer (lyrics) are lovely and include two winners, the Oscar nominated Dearly Beloved and I'm Old Fashioned (whose duet by Astaire and Hayworth is the film's musical highlight). The screenplay (Delmer Daves was one of the co-scripters) is amusing enough to engage us and there are some clever comedic performances particularly Menjou as the acid tongued papa and Gus Schilling providing comic relief as Menjou's put upon secretary. With Isobel Elsom, Adele Mara, Leslie Brooks, Mary Field, Lina Romay and the bandleader Xavier Cugat playing himself and very well, too.
