Time Out saysCompared to even 'sophisticated' juvenile fodder, the sheer exuberance of Disney's adaptation of PL Travers' children's classic should tickle the most jaded fancy. Indeed, the film can hardly contain itself with its catalogue of memorable songs, battery of dance routines, and strong supporting cast. As for the leads, Julie Andrews, after beating off other pretenders to the role (in part because Walt liked the way she whistled), produced an Academy Award-winning portrayal of the Edwardian nanny whose mad magic seethes beneath a patina of respectability that is, as Mary Poppins' references state, 'practically perfect in every way'. But oh, Dick Van Dyke's Cockney accent! You can hardly understand him with his mouth open - but you probably wouldn't recognise him with his mouth closed.
