Imagination is the major raw material of creativity. All kinds of art, from poetry to photography, would have never discovered their means of expression without a plunge into the vast and mysterious fantasy sphere.
It is supposed that fantasy reaches its apogee during childhood and later in life grows dim, in opposition to awakening and maturity. However, the artistic impulse is there, defining all the stages of life, as a deep and inescapable need. Imagination is not really dissipating during growth; it just changes forms according to the trend of mental evolution. A child's imagination is colorful, pure and shiny.
Quite so, all of the following films capture the essence of Lloyd Alexander's words: "Fantasy is hardly an escape from reality. It's a way of understanding it."
