Warwick Thornton is a master maker of images. The first frames of The New Boy – a sweep of dusty ground; a flash of a small boy on a policeman’s back, strangling him; a pre-war telegraph pole, all drenched in the searing white midday light of the desert – create a collage of inland Australia, a world of open spaces. The boy is duly pulled off of the policeman, put in a sack and delivered in the dark to a mission; a nun opens the door to receive the delivery. At that point, the gallery of Thornton’s frame becomes a series of golden brown interiors that could have come from Rembrandt, except that they are peopled with Indigenous boys – Lost Boys, as Sister Eileen (Cate Blanchett) describes them to God – and the trio of adults who look after them.
