You will know from Saving Mr Banks that author PL Travers had major problems with letting go of this, the first of her Poppins series. And she made life hell for Walt Disney and his super-talented team of songwriters, cartoonists, choreographers and writers. And out of that years-long war came a film fashioned from such magical properties as to defy description. It has killer dialogue (“Never mistake efficiency for a liver complaint”), wonderful performances from children and adults alike (it was Andrews’ debut), a terrific blend of pathos and wonderment courtesy of the combination of live action with animation… And then there are the songs, which I knew long before I ever saw the film. Every home had a copy of this album at one time. They are all brilliantly crafted affairs by Disney’s in-house writers the Sherman brothers. Adapted by Bill Walsh and Don DaGradi and directed by Robert Stevenson. If you don’t have a lump in your throat for Let’s Go Fly a Kite you might well be a robot. Practically perfect in every way.
