"The Carioca" is a 1933 popular song with music by Vincent Youmans and lyrics by Edward Eliscu and Gus Kahn, as well as the name of the dance choreographed to it for the 1933 film Flying Down to Rio.
The number was sung in the film by Alice Gentle, Movita Castaneda and Etta Moten and danced by Fred Astaire and Ginger Rogers as part of an extended production dance introducing it.
Though billed fourth and fifth, many felt they stole the film, which became a big hit for RKO.
The song was nominated for the Academy Award for Best Original Song at the 7th Academy Awards, but lost to an even bigger Astaire and Rogers production number, "The Continental" from The Gay Divorcee (1934), their next film together and their first starring vehicle.
25 years later, in May 2019, the Carioca scene of the movie was celebrated in Cannes with a flashmob dance and by the actors themselves who danced again the mythic scene included in "La Cité de la Peur".
