Some people consider this the best of the ten musicals Fred Astaire and Ginger Rogers, one of the most famous dancing teams of all time, made together. I like Top Hat better, but this one comes close. The plot doesn't matter: suffice it to say it involves society, show business, and love, all tangled up by a script that's witty and charming and provides the leads with an excuse to engage in verbal banter and fancy footwork.
