It's Swing Music vs. the Classics in the easy-to-take Warners tunefest Naughty But Nice. Dick Powell dons the obligatory spectacles as a staid music professor Hardwick, who harbors a desire to become a songwriter. With the help of aspiring lyricist Linda McKay (Gale Page), Hardwick pens a little ditty that, through a fluke, becomes a smash hit. Not entirely prepared for show-business success, Hardwick falls into the clutches of predatory vocalist Zelda Manion (Ann Sheridan), leaving poor Linda in the lurch-at least until the last reel. Ronald Reagan breezes through one of his then-typical wiseguy supporting roles, while ZaSu Pitts, Vera Lewis and Elizabeth Dunne are likewise typecast as Hardwick's maiden aunts (conversely, the Professor's other aunt, played by Helen Broderick, is a real hep-cat). Virtually all the Harry Warren/Johnny Mercer songs in Naughty but Nice have been adapted from the works of such past masters as Mozart, Bach and Wagner-and old device, but one which works beautifully here.
