In Hermann Hesse's Nobel prize winning book, the Magister
Ludi was the supreme master of the Glass Bead Game. The modern masters
of the game are the creators of plays and films. Everything in the work
is relevant, nothing is extraneous. If a gun is on the mantel in act
one, it better go off by act three! The good guys are accompanied by
white hats, upscale music, clear skies, and cute animals or children.
The bad guys are evoked with black hats, ominous music, dark scudding
clouds, and scurrying rodents. Every item is metaphorically related to
every other item, and to the theme of the film.
An amusingly forced example is from the film Coming Home.
The returning crippled vet and the cheating wife are having an affair,
and are shopping in the Lucky grocery store together. Her uptight
military husband, who had been planning to kill them, cannot handle the
situation, is walking into the surf to kill himself. As the couple are
leaving, the sign on the door reads, "Lucky Out".
