The most widely seen movie produced by a Hollywood studio, The Sound of Music grows fresher with each viewing. Though it was planned meticulously in pre-production (save for the scene where Maria and the children take a dipping in an Austrian lake that nearly cost a life), on each viewing one is struck anew by the spontaneous almost improvisatory air of the acting, notably of Julie Andrews under Robert Wise's direction.

There are also the little human touches he brings to, for instance, the scene where Maria leads the children to the hills, over bridges and along tow paths where the smallest boy trips up and momentarily gets left behind: it creates a feeling that most of us have encountered.

From the opening pre-credit sequence of muted excitement as the camera roves over the Austrian Alps (photographed in magnificent colour), where little phrases from the wind instruments on the soundtrack are flung as if on the breeze, foreshadowing the title song to follow, the production never puts a foot wrong.
