You'll Never Get Rich was the first of two films made by Fred Astaire at Columbia, and also the first in which he was paired with his favorite female dancing partner--not Ginger Rogers or Cyd Charisse, but Rita Hayworth. Fred and Rita play a team of Broadway dancers whose partnership is abruptly rent asunder when Fred is drafted into the Army. Unable to adapt to military routine, Astaire frequently ends up in the guardhouse; during one of these visits, he and the Delta Rhythm Boys collaborate on the lively song-and-dance number "The A-starable Rag." Back to the plot: Rita shows up on the army base as the girl friend of captain John Hubbard. This leads to more fancy footwork, and, of course, a happy ending for our stars. Though the Cole Porter score yielded no hits, one of the songs, "Since I Kissed My Baby Goodbye", was nominated for an Academy Award. Robert Benchley provides comic relief, as he would in the subsequent Astaire vehicle
The Sky's the Limit. You'll Never Get Rich was followed by the even better Astaire-Hayworth pairing
