Characters growing and then shrinking with power

I love the way the director of this film used the camera to switch power positions by making strong characters grow while weakening characters would shrink. You can see it best when Miss Minchin (TIm Minchin's gamma?) tells Sarah that she is not a princess. At first we are looking down at Sarah and up at Minchin as Minchin tells Sarah that she is not a princess. THen, when Sarah defies her by saying she doesn't believe it, watch how the camera movements make Sarah GROW by falling beneath her, while Minchin shrinks as the camera soars over her, making Sarah look large and strong and Minchin look small and weak. Beautifully done!!
