A delightful musical, mistily photographed in Technicolor, that was never given its due when it first appeared.

The elfin Audrey Hepburn combined with Fred Astaire, still a Peter Pan of the dance floor at 57, to revitalise an enchanting pre-war Gershwin musical romance about a photographer who takes a thin, bookish girl to Paris and transforms her looks and personality.

If you need to be reminded that Fred was still the best musical comedy dancer in the business, watch his bullfighting routine in Let's Kiss and Make-up, and his timing as he talks his way through the songs, especially the title number.

One unexpected pleasure: the real voice of Miss Hepburn (who didn't sing for herself in My Fair Lady) making a throat-catching vocal dream out of How Long Has this Been Going On?

She also dances divinely, providing Astaire with another gamine partner to follow Leslie Caron from Daddy Long Legs. Slightly dated by its fashion themes, it's still a treat.
