Script is amazingly witty, and director holds it all together - gags, music, dancing, romancing - with expertise and musicality, and always with an idea for the unexpected twist and turn. Astaire is unfailingly elegant, especially in his solos and never more so than in the fiery, dynamic rag that he does with the band in the slammer, great scene! Hayworth is divine, no less, sophisticated like no one's business, sexy, piquante. Cliff Nazarro is hilarious as the Swivel Tongue, a private who talks smoothly all the time, yet nobody understands a word he is saying. I wasn't prepared for the greatness of this film that, in the annals, does not stand out as the classic it is.
