The song was written by Arthur Freed and Nacio Herb Brown and first published in 1929, but it became iconic through the 1952 MGM musical Singin' in the Rain. Gene Kelly, who co-directed the film with Stanley Donen, performed it in a rain-soaked street scene that is now one of cinema's most imitated dance sequences. The short clip circulates online as a shorthand for optimism in bad weather, and creators reuse it for parodies, tributes and cheerful edits where a character refuses to let rain spoil the moment.
