Based on a novel by Rosamond Marshall, Kitty ~ played by the pert and very pretty Paulette Goddard ~ is an 18th century guttersnipe (i.e. wanton, poverty-stricken petty thief in this case) who tries to steal from famed English painter Thomas Gainsborough (Gainsborough's celebrated works are the figures Pinky and The Blue Boy). When she is caught, the artist is struck by her good looks under the dirt and rags she wears. Instead of casting her into prison, he hires her to pose for him (in a better set of clothes of course) and when the portrait is exhibited, all of London is enthralled with the mysterious beauty. In on the charade is the attractive but penniless and mercenary fop, Sir Hugh Marcy (Ray Milland), who takes Kitty in as a servant for the household he shares with his aunt, Lady Susan Dowitt (Constance Collier). Seeking revenge on the Duke of Malmunster (Reginald Owen, in rare form), who is fascinated with Kitty's portrait, Sir Hugh tries to pass his ward off as a lady to the Duke, with both humorous and sinister bumps along the way.The costumes are quite magnificent, much more authentic than the recent film The Duchess. The dialog is quite witty especially with such an array of characters, representative of all walks of life. Kitty is a fun and funny film, not without poignancy, both innocent and romantic, the like of which is no longer made.
