Franz and Fiala kick off on a sly note with the most wholesome image of Austrian family togetherness, the Von Trapp children and their stepmother singing a sweet lullaby. The co-directors then jump to a bracing sequence set within the vivid green foliage of a cornfield, where Lukas and Elias (played by brothers Lukas and Elias Schwarz) are in the midst of a vigorous game of tag. The sinister homemade animal mask worn by one of the boys sets up the disturbing recurring motif of hidden faces.
